Description

The invention relates to a climbing device with at least one climbing rail for adjusting and/or climbing scaffolding and/or formwork and/or a platform according to the preamble of claim 1 and a corresponding climbing system.

State of the art

When building or producing walls, storey ceilings, suspended ceilings or roofs, etc., ie especially in the formwork and scaffolding area, climbing devices such as climbing scaffolds, transfer platforms, climbing formwork are preferably those that are usually used on a building or structure to be erected out of concrete Buildings, especially high-rise buildings, wind turbines, storage silos, bridge pillars or power plant and cooling towers, etc., are arranged and are components of a so-called climbing system or climbing formwork the concreting of a section of a building wall (without external help) is lifted by one section higher, ie autonomously or "autonomously climbs up" so that another section of the wall can be concreted there.

The essence of such a transfer platform is that it does not have/needs a direct connection to the ground when climbing and is only attached to the already concreted section below the section to be concreted using climbing or so-called "support shoes". For each formwork panel, two supporting rails arranged next to one another at a distance are usually provided. In principle, however, an embodiment with only one mounting rail in the middle of a formwork panel is also possible.

In principle, these climbing devices can also be used for the horizontal or diagonal upward shifting/climbing of tunnel formwork carriages, reinforcement carriages, mobile wall formwork, e.g. for retaining walls or the like.

The climbing systems already in use have to be synchronized with neighboring climbing devices or climbing rails due to the large concreting and thus formwork widths, whereby this often cannot be maintained by constant observations and corrections.

Such self-climbing devices (cf. e.g DE 10 2005 030 336 A1 or DE 10 2005 030 335 A1 ) have at least one linear drive or one hydraulic drive/cylinder, which generates a relative movement between at least one sliding bracket and at least one support/climbing rail running in the direction of displacement, with the connection between the linear drive and the support rail being made by spaced-apart climbing shoes or so-called climbing heads, which usually have a pivotable locking member or the like and with locking cams cooperating with the locking member in the path of the locking member on the supporting rail traversed during a relative movement between the support rail and the climbing head/climbing shoe, with the locking member during the relative movement in one direction over the blocking cam is lifted away, but runs onto the blocking cam in the other direction of movement, so that one climbing head/shoe is positively connected to the support rail, blocking this relative movement, while the other climbing head/shoe is on e the locking cam overcoming relative movement takes place.

When climbing, the scaffolding section has no direct connection to the ground, and no crane is required if a linear drive, e.g. a hydraulic drive, is provided on the scaffolding, which in one work step drives the scaffolding section to the support rail and in the other workstep the support rail relative to the scaffolding section lifts.

However, the disadvantage of the previous climbing devices is that the hydraulic hoses are several meters long must be coupled and uncoupled between the hydraulic cylinders or support rails for each section or floor. On the one hand, this results in leaks/losses, as a result of which the tank/reservoir of hydraulic fluid is emptied after a certain time and has to be refilled.

On the other hand, the harsh, dirty conditions on the construction site can result in contamination of the hydraulic connections and damage to the hydraulic pressure hoses lying around meters long on the scaffolding or climbing device, which impairs or damages the hydraulic system and even a (temporary) stoppage of operation and repair or replacement the pressure hoses can cause.

In addition, there are power losses in the hoses, which are many meters long, which the central hydraulic pump has to compensate for or there is a pressure drop on the individual cylinders and thus reduces the climbing/lifting power. At the same time, the smallest hydraulic differences/tolerances of the components used mean that a complex calibration of the (several) hydraulic cylinders is necessary in order to ensure the most precise possible synchronization of these several cylinders or scaffolding modules/formworks.

For safety reasons, ie due to the fact that some people are also lifted with the climbing device, the hydraulic components, especially meter-long pressure hoses, must meet the highest requirements, which both means high maintenance and service/replacement costs.

Object and advantages of the invention

In contrast, the object of the invention is to propose a climbing device with at least one climbing rail for adjusting and/or climbing scaffolding and/or formwork and/or a platform, which at least partially avoids or at least reduces the disadvantages of the prior art.

Starting from a climbing device with at least one climbing rail for adjusting and/or climbing scaffolding and/or formwork and/or a platform of the type mentioned above, this object is achieved by the characterizing features of claim 1 . Advantageous embodiments and developments of the invention are possible as a result of the measures mentioned in the subclaims.

Accordingly, a climbing device according to the invention is characterized in that the hydraulic cylinder is designed as a hydraulic unit, the hydraulic unit having at least one hydraulic tank for storing hydraulic fluid, an electric motor and a hydraulic pump driven by the electric motor for pressurizing the hydraulic fluid.

According to the invention, at least a first hydraulic unit and a second hydraulic unit are provided, in particular numerous hydraulic units or hydraulic structural units, with at least one electrical connecting line between the first and the second hydraulic unit or between all hydraulic units or hydraulic structural units (each) for the electrical and / or electronic connection and / or for electrical power supply and / or for electronic data or information transmission is arranged.

With the help of these measures , it is achieved that the hydraulic unit is designed in an advantageous manner as a hydraulic unit that can be handled separately. This or each hydraulic unit/assembly is assigned to a climbing rail. For example, in a relatively large building formwork with 20 or 30 climbing rails, 20 or 30 hydraulic units/assemblies are used according to the invention, so that not only 20 or 30 hydraulic cylinders are used, but also, according to the invention, 20 or 30 hydraulic tanks, 20 or 30 electric motors and 20 or 30 hydraulic pumps available. This means that a hydraulic unit/assembly that is as complete or hydraulically fully functional/autonomous as possible can be implemented, which is (directly) arranged on a climbing rail or is operatively connected to an associated climbing rail in order to adjust the relative displacement between structure/building and the climbing device /-system/-scaffolding or climbing/lifting the climbing device according to the to realize invention.

In this way, according to the invention, meter-long hydraulic hoses, among other things, can be avoided or they no longer have to be used. Accordingly, the particularly trouble-prone pressure hoses or flexible/elastic hydraulic lines, which previously lay around several dozen meters long on a scaffolding or a climbing device according to the prior art or had to be inserted between the individual hydraulic cylinders or climbing rails, can be completely removed omitted. By not using long, flexible, hydraulic pressure hoses between the different hydraulic cylinders or rails according to the invention, a clear improvement in operational safety and the avoidance of contamination of the hydraulic system or circuit is already achieved. For example, so-called plug-in couplings or the like on/between the individual hydraulic cylinders can be completely avoided.

The hydraulic unit/assembly advantageously includes rigid and/or permanently fixed hydraulic lines, especially metal pipes with screw connections, pinch connections or the like, preferably between the hydraulic cylinder and the hydraulic pump and/or between the hydraulic pump and hydraulic tank/hydraulic accumulator. It is essential here that these hydraulic lines are not detached and then reconnected/coupled/screwed on during operation or before and after a climbing operation phase. Rather, these hydraulic connections/connections are made during the assembly/manufacture of the hydraulic unit/assembly generated/made, e.g. firmly screwed on or squeezed, and only in the case of a repair or an exchange of the hydraulic cylinder and/or the hydraulic pump and/or the hydraulic tank/hydraulic accumulator these are to be loosened.

Accordingly, a so-called “lifetime filling” of the hydraulic tank/hydraulic accumulator or hydraulic circuit can be implemented. This means that during the production

Assembly of the hydraulic unit/assembly the hydraulic fluid is introduced/filled in and if possible lasts the entire service life of the hydraulic unit/assembly or does not need to be refilled.

In an advantageous variant of the invention, each of the first and second hydraulic units or hydraulic structural units has a housing jacket and/or a housing frame, with at least the cylinder housing of the hydraulic cylinder, the hydraulic tank, the electric motor and the hydraulic pump being at least partially within the housing jacket and/or housing frame are arranged or fixed. This improves the (separate) manageability of the hydraulic unit or hydraulic structural unit. In addition, the hydraulic unit or hydraulic structural unit is also protected against impairments or damage (from the outside) by means of the housing shell and/or housing frame.

This is a great advantage, especially in the rough, dirty conditions on the construction site. For example, a toppling/falling (heavy) element/tool is advantageously prevented from reaching an "inner part" or to damage an internally arranged component, in particular a pressurized element/pipe and/or an electronic/electrical element such as a circuit board, an electronic unit etc. This additionally increases the operational safety of the climbing device according to the invention.

The housing jacket can preferably be designed to be almost completely closed, i.e. have an almost closed jacket/enveloping surface. For example, a plastic and/or metal housing is used as the housing jacket for each of the first and second

Hydraulic units or hydraulic units provided.

However, within the meaning of the invention, the housing shell can also have openings, recesses or passages or the like. If necessary, only a rigid frame or the like is designed as the housing frame within the meaning of the invention, which holds the corresponding elements/components of the hydraulic unit or hydraulic assembly according to the invention together, in particular with or without the above-mentioned housing jacket, so that the hydraulic unit can advantageously be used as a is designed separately manageable unit or as a one-piece unit.

In a particular development of the invention, (rigid and/or permanently connected) hydraulic lines/pipes for the hydraulic connection of the hydraulic pump to the hydraulic cylinder and/or between the hydraulic pump and the hydraulic tank/hydraulic accumulator are provided within the housing shell and/or housing frame and/or each of the first and second hydraulic units or hydraulic structural units comprises a closed hydraulic circuit. This becomes one advantageous hydraulic self-sufficiency or independence of the hydraulic unit or hydraulic assembly according to the invention can be realized. In this way, each of the first and second hydraulic units or hydraulic structural units can be used/positioned and operated in a particularly flexible manner.

In principle, it is conceivable that, for example, each of the first and second hydraulic units or hydraulic structural units is designed and/or arranged so that the climbing device according to the invention can not only be raised, but also that each of the first and second hydraulic units or hydraulic structural units lifts or climbs (with) itself. The latter means that the hydraulic cylinders fixed at one end to the building etc. after climbing or the climbing phase, ie lifting phase, which usually includes several climbing steps, are not, as was previously necessary, dismantled or dismantled and carried to the next floor or floor above must be, but that each of the first and second hydraulic units or hydraulic structural units raises itself after a climbing step or after the climbing / lifting phase or even realizes a climbing step. Here, for example, a double-sided or double-acting hydraulic cylinder is advantageous, so that the extended piston rod with a fixed (upper) End raises the lower end and/or the cylinder or the cylinder housing or each of the first and second hydraulic units pulls itself up. Accordingly, it is conceivable that one end of each of the first and second hydraulic units is always fixed in place and the other end of each of the first and second hydraulic units is adjusted or raised in alternation.

This would mean dismantling on a lower floor and the subsequent transport or carrying by one person and the subsequent assembly of the hydraulic system or each of the first and second hydraulic units to / on an upper floor is unnecessary.

For example, an energy supply device of each of the first and second hydraulic units has at least one electrical connection element for supplying electrical energy. Preferably, only an electrical energy supply and no hydraulic energy supply is provided as the energy supply for each of the first and second hydraulic units or hydraulic structural units. Thus, only electrical cables/connections between two or more hydraulic units or hydraulic structural units can/must be provided. With this, a significantly more flexible energy supply for climbing or lifting the climbing device or a complex/larger climbing system with numerous climbing devices and/or hydraulic units or hydraulic structural units can be implemented. The effort for the energy supply is hereby decisively reduced/improved.

In addition, energy losses are avoided as with the previous hydraulic energy supply systems or meter-long hydraulic hoses. This increases the efficiency of energy use.

Advantageously, each of the first and second hydraulic units or hydraulic units on an electrical energy store, esp. Accumulator such as lithium-ion battery etc., and / or an electrical energy source or electric generator such as a solar cell or photovoltaic unit. This enables complete (energetic) self-sufficiency or

Independence of the individual hydraulic unit or hydraulic units can be realized. For example, solar energy can be used together with an electrical energy store, with the energy store being charged with solar energy or a photovoltaic unit, which is used for pressure generation and/or electrical monitoring/control/regulation. This is of great advantage, especially with climbing devices according to the invention, since the climbing phase is comparatively short, e.g. approx. 20 to 50 minutes, and then there is a relatively long construction/concreting phase, e.g. approx. 2 to 5 hours or even a day or longer, i.e. a rest phase of each of the first and second hydraulic units or hydraulic structural units, which corresponds to an operating phase without climbing or without climbing energy consumption. Accordingly, a comparatively small photovoltaic unit or the like, especially in sunny locations/countries, can advantageously charge the electrical energy store or store a comparatively large amount of electrical energy and then subsequently the electric motor or the pressure generation and thus the climbing/lifting of the climbing device of the invention in the relatively short climbing phase.

Each of the first and second hydraulic units preferably has at least one electrical and/or electronic control unit for controlling at least the hydraulic cylinder and/or electric motor. It can hereby be achieved that, especially when using at least two or more hydraulic units or hydraulic structural units advantageous electrical/electronic adjustment or synchronization of the hydraulic cylinders is guaranteed/implemented. A climbing system or a combination with, for example, approx. 11 to 50 hydraulic cylinders/units or hydraulic structural units can be electronically/electrically monitored or controlled in order to achieve uniform climbing of the climbing device. Complex hydraulic balancing or calibration as in the prior art is no longer necessary.

At least one electrical and/or electronic central unit is preferably provided for controlling at least the first and the second hydraulic unit and/or all hydraulic units or hydraulic structural units. For example, the central unit is integrated in the first hydraulic unit, so that the first hydraulic unit is designed as a master hydraulic unit and the second hydraulic unit and/or further hydraulic units are designed as slave hydraulic units.

Alternatively or in combination with this, the central unit can also be designed as a separate component/unit of the climbing device according to the invention, which is connected to the hydraulic unit(s) electrically and/or electronically or by cable and/or wirelessly or by data transmission/radio transmission. For example, the central unit can be designed as a computer, notebook, laptop, PDA, smartphone or the like. The connection between hydraulic units or hydraulic structural units and/or between hydraulic units and the central unit advantageously includes at least one transmitter and/or receiver for wireless information or data transmission between at least two hydraulic units or hydraulic structural units and/or between the control unit and/or central unit and/or the hydraulic units etc. With the help of such a radio connection between two hydraulic units or hydraulic structural units or the control and/or central unit, a particularly flexible data connection or control/control/monitoring of the climbing device according to the invention is possible. This reduces the cost of laying the cables, for example between corresponding units or between the hydraulic units or hydraulic structural units that are sometimes several (dozen) meters apart.

In a particular development of the invention, the electrical and/or electronic control unit or the addressable control unit is designed as a control unit for checking the operating state of the hydraulic units or hydraulic structural units. The control unit preferably includes an addressable interface to a digital data transmission unit. This measure ensures that the hydraulic unit or hydraulic structural unit can be controlled or controlled/monitored if the digital data transmission unit receives addressed data or data with the corresponding address of the hydraulic unit or hydraulic unit transmits to the addressable interface. Accordingly, the interface advantageously switches or connects the electrical energy/information of the hydraulic units or hydraulic structural units if the address is correspondingly transmitted or correct. Data/information is preferably transmitted separately from the power supply. In this case, two energy conductor elements or electrical supply cables/lines are now sufficient for supplying energy to the hydraulic units or hydraulic structural units.

Advantageously, a plurality of hydraulic units or hydraulic structural units are connected in series with respect to the energy supply, or a single circuit is provided for a plurality of hydraulic units or hydraulic structural units. The control or the adjustment/synchronism is advantageously implemented by the addressing. This means that, for example, in the case of several, e.g. 20 to 40, hydraulic units or hydraulic structural units, a specific hydraulic unit or hydraulic structural unit is controlled/controlled if the associated address, which is transmitted to the addressable interface by means of the digital data transmission unit, and with an advantageously Way fixed address of the specific interface or hydraulic unit or hydraulic assembly matches. Accordingly, the interface switches or connects the respective hydraulic unit or the respective electric motor of the hydraulic pump to the power supply in order to adjust/extend the piston or adjust the Checking/regulating the adjustment of all hydraulic cylinders.

If the address transmitted by means of the data transmission unit does not match the specified address of the hydraulic unit, the interface of the corresponding hydraulic unit or hydraulic structural units does not switch or the electric motor is operated or supplied with energy unchanged. This means that there is no change or adjustment/correction of the extension speed of the piston.

In a special development of the invention, essentially each of the hydraulic units or hydraulic structural units is assigned at least one address and/or a code. With the help of such addressing or coding of the individual hydraulic units or hydraulic structural units, an unambiguous or advantageous assignment can be implemented. This is of particular advantage in the case of wireless data transmission between the hydraulic units or hydraulic structural units.

In an advantageous variant of the invention, at least one electrical data memory is provided for storing the operating states of at least one of the hydraulic units or hydraulic structural units and/or hydraulic cylinders. With the help of such an advantageous data memory, for example, statistical evaluations, among other things, can advantageously be carried out for a specific operating period, such as for an operation or a construction site or, for example, a month or a year will be realized. For example, errors, impairments, etc. of the hydraulic units or hydraulic structural units can be stored or determined accordingly.

At least one display unit is preferably provided for the visual display of the operating states of at least one of the hydraulic units or hydraulic structural units and/or the hydraulic cylinder. In particular, the display unit is designed as a screen. With the help of such an advantageous visual display, there are completely new possibilities for central monitoring or remote monitoring of a number of hydraulic units or climbing devices according to the invention.

In addition, the visual representations of the stored operating states or statistically evaluated operating states and/or actual states during the climbing phase can also be realized with the display unit.

The display unit is preferably designed to display all hydraulic units or hydraulic structural units and/or data connections. Overall monitoring of all the components or hydraulic units or hydraulic assemblies involved is advantageously possible in this way. This is particularly advantageous for a site manager, master craftsman, managing director or the like, for example in order to have the individual hydraulic units or hydraulic structural units and thus the individual hydraulic cylinders or the like centrally located or to record them together, if necessary to view or check them with a time delay with the aid of the advantageous storage and/or to carry out statistical calculations and display them in an advantageous manner. This allows an optimization of the operation of the climbing phase or climbing device to be monitored according to the invention to be implemented in a new way.

In order to display and/or store and calculate statistical evaluations or the like, a computer, preferably a notebook, a so-called PDA, but also a mobile phone or other portable electronic media are of particular advantage.

Particularly when using computers, notebooks, PDAs or the like, this advantageously includes the entire operation of the climbing device or the climbing system according to the invention. For example, electronic devices of this type are linked or integrated into the hydraulic unit or hydraulic structural unit via advantageous or commercially available interfaces. For example, so-called bus systems can be used here, such as USB, RS232, Ethernet, etc., but also wireless communication systems such as Bluetooth, etc. According to the invention, a complex network with several hydraulic units or hydraulic structural units and, if necessary, computers, mobile phones, PDAs or the like be realized, which allow the display of the operating states of different hydraulic units or hydraulic assemblies.

In general, a hydraulic unit or hydraulic structural unit can also include other units such as e.g. acoustic signaling, other sensors for status detection, etc. Their operating states or signals can advantageously be treated like the operating states of the hydraulic units or hydraulic structural units or transmitted to the control unit or the central unit and possibly displayed in accordance with the explanations presented above. In this way, further functions or controls of the hydraulic units or hydraulic structural units can be implemented in an advantageous manner.

In principle, it is also conceivable that an integration for the operation of the climbing device according to the invention or new functionalities of corresponding (mobile) telecommunications devices can be implemented without great effort by means of advantageous programming, for example by means of so-called app programming or the like. For example, the manufacturer of a climbing device according to the invention provides corresponding software or "apps" for the customer or user of the climbing device according to the invention. This can be implemented, for example, by long-distance data transmission or the Internet or the like, so that the user can use his mobile telecommunications device (with an Internet connection) such as a smartphone, tablet or the like, which is already available for private reasons, then also to configure or change the Settings and / or display or monitoring / control climbing devices according to the invention can use. This will create a additional functionality of the climbing device realized according to the invention. For example, the outlay for monitoring and/or displaying the climbing device or a relatively complex/larger climbing system is reduced to a considerable extent.

A high degree of operational reliability is achieved in the climbing device by appropriate codification or modulation and/or encryption of the wireless setting information. For example, a display/monitoring/control with a mobile telecommunications device can also be secured against unwanted manipulation using a password or corresponding access code.

In principle, the customer/user can carry out or receive the information for the configuration or setting of the operating parameters and/or operation via the Internet and/or via "App" or the like and save it on appropriate telecommunications devices and then transfer the information or settings or advantageously wirelessly transmit the configurations to the climbing device according to the invention. Also, for example, an advantageous simulation of selected operating parameters or the "envisaged" operating parameters can be simulated and varied on a website, an "app" or with the help of the (mobile) telecommunications device on the screen. For example, pressure forces, piston speeds, soft start and / or soft stop or so-called Signal tones, esp. Their volume, frequency or pulsating, falling etc. and/or tone sequences or melodies or the like can be viewed or listened to and/or set or uploaded using the advantageous telecommunications device and, according to the invention, to the climbing device be transmitted wirelessly and thereby configured according to the invention or their operating parameters are set accordingly.

At least one piston sensor is preferably provided for detecting the position/adjustment of the drive piston of the hydraulic cylinder, in particular a volume measurement sensor or a cable sensor or the like. With this, the actual position of the drive piston and preferably of all drive pistons of all hydraulic cylinders can be determined. An adjustment or a separate control/control of the individual hydraulic cylinders or (separately) all hydraulic units or hydraulic structural units can thus advantageously be implemented with the control unit in order to achieve a largely exact synchronization of the climbing process or the climbing device according to the invention to guarantee.

In principle, any number of hydraulic units or hydraulic structural units can be combined with one another according to the invention, especially all existing/required and/or an even or an odd number of hydraulic units or hydraulic structural units. In contrast, so-called flow dividers were used in the prior art in order to hydraulically operate two cylinders with a common pump in synchronism, which means that only allowed an even number of hydraulic cylinders to be used. The electrical/electronic adjustment or synchronism according to the invention is thus significantly more flexible and can be used in almost unlimited ways.

schematically shows a topology or interconnection of several hydraulic units and a separate central unit of a climbing device according to the invention.

In figure 1 a hydraulic unit 1 of a climbing device for adjusting and/or climbing a scaffolding and/or formwork and/or platform, not shown in detail, is shown schematically according to the invention. The hydraulic unit 1 includes a hydraulic cylinder 2, an electric motor 3, a hydraulic pump 4 and a hydraulic tank 5 for storing hydraulic fluid/oil. In addition, the electric motor-driven pump 4 has a control block 6.

In addition, the hydraulic unit 1 includes an electronics unit 7 or control unit, in particular for controlling/controlling/regulating and monitoring the electric motor 3 and/or a sensor 11 and/or an indicator/signal light 9. The sensor 11 is preferably designed as a displacement sensor 11 and arranged in the hydraulic cylinder 2 or in the cylinder housing 12 in order to detect an adjustment or an extension/retraction of a piston 10 and to transmit signals/data to the electronics 7, among other things.

The hydraulic unit 1 also has a housing 13 in which the components mentioned above are arranged and protected. In the present case, it is an embodiment as a closed housing shell, so that the components/elements arranged/integrated in it are protected from dirt and/or damage etc. The hydraulic unit 1 can thus be carried by one person as a one-piece structural unit, preferably by means of two carrying handles 17 .

However, comparatively large/heavy hydraulic units 1 according to the invention can also be realized/used as a one-piece assembly that can be too heavy for one person, so that these large/heavy hydraulic units 1 are preferably equipped with a lifting device such as an elevator, lifting platform, crane or the like is to be transported, especially between the construction sections, floors of the building, platforms of the scaffolding, etc..

The hydraulic unit 1 thus includes hydraulic components on the one hand and electrical/electronic components/actuators/sensors on the other hand, so that the hydraulic unit 1 can also be referred to as a “hybrid cylinder” here. This means that two technologies are combined with one another in the hydraulic unit 1 according to the invention, namely the hydraulics and the electrics/electronics in the present case.

The hydraulic unit 1 also has several electrical Plug 8 or connector 8, so that the electrical power supply to the hydraulic unit 1 is guaranteed. For example, several plugs 8 are provided, on the one hand to supply energy to the electric motor 3 and/or the electronics 7 and on the other hand to transmit energy to a second hydraulic unit 1 (cf. figure 4 ).

Furthermore, separate electrical plugs or the like can also be provided in order to implement an electrical/electronic network or a digital bus system/network. This networking of several hydraulic units 1 can accordingly be carried out as in figure 4 shown schematically include any number of hydraulic units 1. In this case, the hydraulic units 1 can be connected to one another/to one another and/or to a separate, central control unit 19 by means of electrical connecting cables 20 for energy supply and/or for data/information transmission. The data/information transmission in particular can also be implemented wirelessly or by means of a transmitter and receiver.

Climbing scaffolds or rail climbing systems have been in use for a long time, so that a comprehensive representation and description of the climbing device according to the invention with all components and their mode of action or cooperation/work processes is largely omitted, since these are known in principle to the person skilled in the art.

In the present case, only the hydraulic unit 1 according to the invention and its arrangement in figure 3 a bit closer to be discribed. In figure 3 two climbing shoes 15, 16 are shown, which are coupled to a climbing rail 14 in a known manner. The climbing shoes 15, 16 can be adjusted/moved along the climbing rail 14 so that the hydraulic unit 1 is guided on/with the climbing rail 14. The climbing shoe 15, 16 has a locking system known to those skilled in the art, with which its direction of movement is predefined. A process/adjustment in the opposite direction is not possible without influencing the climbing shoes 15, 16.

A support shoe 17 couples an unspecified scaffolding/platform or the like to the climbing rail 14. The climbing operation is compared between the two Figures 3a) and 3b ) clear. In Figure 3a ) a rod side of a cylinder 2 is supplied with hydraulic fluid/oil or pressurized via the hydraulic unit 1. Climbing shoe 15 prevents downward movement, so climbing shoe 16 moves in the direction of cylinder 2.

In Figure 3b ) a bottom side of the cylinder 2 is supplied with oil via the hydraulic unit 1. The climbing shoe 16 prevents downward movement, so the climbing shoe 15 and the support shoe 17 are moved by the cylinder stroke. A climbing step is thus completed. The operating states according to Figure 3a) and 3b ) are repeated until the desired position of the platform or the like, not shown in detail, is reached.
