EP3339535B1 - Climbing device with a climbing rail - Google Patents

Description

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

State of the art

In the construction or production of walls, floors, ceilings or roofs, etc., dhva in the formwork and scaffolding, it is in climbing devices such as climbing frames, moving platforms, climbing formwork preferably those that are usually on a building to be built from concrete or Buildings, esp. High-rise building, wind turbine, storage silo, bridge piers or power stations and cooling towers, etc., are arranged and components of a so-called climbing system or a climbing formwork are, according to the concreting of a section of a building wall (unassisted) is raised by one section, ie autonomously or "autonomously climbs up", so that there another section of the wall can be concreted.

The essence of such a transfer stage is that it has no direct connection to the ground when climbing and / or is attached only at the below the concrete section to be concreted and already finished concreted by climbing or so-called. "Support shoes". For each formwork panel usually two juxtaposed spaced support rails are provided. In principle, however, a design with only one support rail in the middle of a formwork panel is possible.

Basically, these climbing devices are also for horizontal or obliquely upward displacement / climbing of tunnel formwork carriage, rebar, mobile wall formwork, e.g. suitable for retaining walls or the like.

Due to the large concrete and thus shuttering widths, the climbing systems already in use must be synchronized with neighboring climbing devices or climbing rails, and this can often not be maintained by constant observation and correction.

Such self-climbing devices (cf., eg DE 10 2005 030 335 A1 such as DE 38 42 094 A1 ) have at least one linear drive or a hydraulic drive / cylinder, which generates a relative movement between at least one sliding console and at least one extending in the direction of support / climbing rail, wherein the connection between the linear drive and the mounting rail by spaced apart climbing shoes or so-called climbing heads is made, which usually have a pivotable locking member or the like and cooperating with in the case of a relative movement between the mounting rail and climbing / climbing shoe trajectory of the locking member on the support rail with the locking member cooperating locking cam, wherein the locking member in the relative movement in one direction the locking cam is lifted, but runs in the other direction of movement on the locking cam, so that a climbing head / shoe locking this relative movement is positively connected to the support rail, while at the other climbing head / -sch uh a locking cam overcoming relative movement takes place.

DE 10 2005 030 335 A1 discloses a climbing apparatus according to the preamble of claim 1.

The scaffolding section has no direct connection to the ground during climbing, nor is a crane required if a linear drive, e.g. a hydraulic drive is provided which raises the support rail relative to the frame section in one step, the framework section on the support rail and in the other step.

A disadvantage of the previous climbing equipment, however, is that over several meters long hydraulic hoses between the hydraulic cylinders or DIN rails must be disconnected and disconnected at each section or floor. As a result, on the one hand leaks / losses, which after a certain time the tank / memory of the hydraulic fluid is drained and must be refilled.

On the other hand, in harsh, dirty construction site conditions, contamination of the hydraulic connections and damage to the hydraulic hoses, meter long on the scaffolding or the climbing device may occur, which impairs or damages the hydraulic system and even a (short-term) shutdown and repair or replacement which can cause pressure hoses.

In addition, there are power losses in the many meters long hoses, which must compensate for the central hydraulic pump or a pressure drop occurs at the individual cylinders and thus reduces the climbing / lifting force. 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 exact possible synchronization of these multiple cylinders or scaffold modules / formworks.

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

Purpose and advantages of the invention

The object of the invention is in contrast a climbing device with at least one climbing rail for adjusting and / or climbing a scaffolding and / or a formwork and / or a platform to propose that realizes a particularly high reliability, especially in conjunction with other, similar climbing equipment.

This object is achieved on the basis of a climbing device with at least one climbing rail for adjusting and / or climbing a scaffolding and / or a formwork and / or a platform of the aforementioned type, by the characterizing features of claim 1. The measures mentioned in the dependent claims advantageous embodiments and developments of the invention are possible.

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

With the help of this measure it is achieved that the hydraulic unit is advantageously designed as a separately manageable hydraulic unit. This or each hydraulic unit / unit is assigned to a climbing rail. For example, 20 or 30 hydraulic units / units are used in a relatively large structural formwork with 20 or 30 climbing rails according to the invention, so that not only 20 or 30 hydraulic cylinders, but also according to the invention also 20 or 30 hydraulic tanks, 20 or 30 electric motors and 20 or 30 hydraulic pumps available. This means that as complete as possible or hydraulically fully functional / self-contained hydraulic unit / unit is realized, which is (immediately) arranged on a climbing rail or in each case with an associated climbing rail in operative connection to the relative adjustment between the building / building and the climbing device / -system / scaffolding or climbing / lifting the climbing device according to the invention to realize.

Hereby, according to the invention, inter alia meter long hydraulic hoses can be avoided or they no longer have to be used. Accordingly, the particularly prone to failure pressure hoses or flexible / elastic hydraulic lines, which were previously about a few tens of meters long on a scaffolding or a climbing device according to the prior art around or had to be used between the individual hydraulic cylinders or climbing rails, completely omitted. Through this Non-use of long, flexible, hydraulic pressure hoses according to the invention between the different hydraulic cylinders or rails is already realized a significant improvement in the reliability and avoiding contamination of the hydraulic system or cycle. For example, so-called plug-in couplings or the like on / between the individual hydraulic cylinders can be completely avoided.

Advantageously, the hydraulic unit / unit comprises rigid and / or fixed hydraulic lines, esp. Metal tubes with screw terminals, squeeze ports 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 released during operation or before and after a climbing operation phase and reconnected / coupled / screwed on. Rather, these hydraulic connections / connections are generated / made during assembly / manufacture of the hydraulic unit / assembly, e.g. screwed or crushed, and only in case of repair or replacement of the hydraulic cylinder and / or the hydraulic pump and / or the hydraulic tank / hydraulic accumulator they are to be solved.

Accordingly, a so-called "lifetime filling" of the hydraulic tank / hydraulic accumulator or hydraulic circuit can be realized. This means that in the production or assembly of the hydraulic unit / assembly, the hydraulic fluid is introduced / filled and as possible the entire life of Hydraulic unit / unit survives or does not need to be refilled.

According to the invention, the hydraulic unit or hydraulic unit on a housing shell and / or a housing frame, wherein at least the cylinder housing of the hydraulic cylinder, the hydraulic tank, the electric motor and the hydraulic pump are at least partially disposed within the housing shell and / or housing frame or fixed. This improves the (separate) manageability of the hydraulic unit or hydraulic unit. In addition, the hydraulic unit or hydraulic unit is protected by means of the housing shell and / or housing rack against impairments or damage (from the outside). This is a great advantage, especially in the rough, dirty construction site conditions. For example, a falling / falling (heavier) element / tool with the help of the housing shell and / or housing rack in front of an "inner part" or an internally arranged component, esp. A pressurized element / tube and / or an electronic / electrical element such as a circuit board, an electronic unit, etc., damage. This additionally increases the reliability of the climbing device according to the invention.

Preferably, the housing shell can be formed almost completely closed, ie have a nearly closed shell / envelope surface. For example, a plastic and / or metal housing as housing shell of Hydraulic unit or hydraulic unit provided. Allerding can in the sense of the invention, the housing shell also openings, recesses or passages or the like. Optionally, only a rigid frame or the like is designed as the housing rack in the sense of the invention, which holds the corresponding elements / components of the hydraulic unit or hydraulic unit according to the invention, esp. With or without an above-mentioned housing shell, so that the hydraulic unit in an advantageous manner separately manageable unit or is designed as a one-piece unit.

In a particular embodiment of the invention, hydraulic lines / pipes for hydraulic connection of the hydraulic pump to the hydraulic cylinder and / or between hydraulic pump and hydraulic tank / hydraulic accumulator are provided within the housing jacket and / or housing rack (and / or the hydraulic unit or Hydraulic unit comprises a closed hydraulic circuit. Hereby, an advantageous hydraulic Autarkie or independence of the hydraulic unit or hydraulic unit according to the invention can be realized. Thus, the hydraulic unit or hydraulic unit can be used very flexible / positioned and operated.

In principle, it is conceivable that, for example, the hydraulic unit or hydraulic unit is designed and / or arranged so that the climbing device according to the invention can not only be raised, but that additionally the hydraulic unit or hydraulic unit raises itself or (self-) climbs. The latter means that not as hitherto necessary, fixed at one end fixed to the building, etc. Hydraulic cylinder after climbing or usually several climbing steps comprehensive climbing phase, ie lifting phase, dismantled or dismantled and carried to the next or above floor / floor must but that the entire / inventive hydraulic unit or hydraulic unit after a climbing step or after the climbing / lifting phase itself lifts or even realizes a climbing step. Here, for example, a two-sided or double-acting hydraulic cylinder is advantageous, so that the extended piston rod at fixed (upper) end raises the lower end and / or the cylinder or the cylinder housing or the hydraulic unit pulls itself up. Accordingly, it is conceivable that always alternately one end of the hydraulic unit is firmly fixed and the other end of the hydraulic unit is adjusted or raised. Thus, the disassembly on a lower floor and the subsequent transporting or carrying by a person and the subsequent installation of the hydraulic system or the hydraulic unit to / on an upper floor would be dispensable.

For example, a power supply device of the hydraulic unit has at least one electrical connection element for supplying electrical energy. Preferably, only an electrical power supply and no hydraulic power supply is provided as a power supply of the hydraulic unit or hydraulic unit. Thus, only electrical cables / connections between two or more hydraulic units or hydraulic Building units are provided. This is a much more flexible power supply climbing or lifting the climbing device or a complex / larger climbing system with numerous climbing devices and / or hydraulic units or hydraulic units realized. The effort for the energy supply is hereby decisively reduced / improved.

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

The hydraulic unit or hydraulic unit advantageously has an electrical energy store, in particular a rechargeable battery such as a lithium-ion rechargeable battery, etc., and / or an electrical energy source or an electrical generator such as, for example, a solar cell or photovoltaic unit. Hereby, a complete (energetic) autarky or independence of the individual hydraulic unit or hydraulic units can be realized. For example, a solar energy use can be used together with an electrical energy storage, wherein the energy storage is loaded with solar energy or a photovoltaic unit, which is used for pressure generation and / or electrical control / regulation. This is especially in climbing devices according to the invention of great advantage, since the climbing phase is relatively short, eg about 20 to 50 minutes and then a relatively long construction / concreting phase is present, for example, about 2 to 5 hours or even a day or longer, ie a rest phase of the hydraulic unit or hydraulic unit, which corresponds to an operating phase without climbing or without climbing energy consumption.

Accordingly, a relatively small-sized photovoltaic unit or the like, esp. In sunny places / countries, load the electrical energy storage or store comparatively much electrical energy and then subsequently the electric motor or the pressure generation and thus the climbing / lifting the climbing device according to provide the invention in the relatively short climbing phase.

Preferably, the hydraulic unit has at least one electrical and / or electronic control unit for controlling at least the hydraulic cylinder and / or the electric motor. This makes it possible to ensure that an advantageous electrical / electronic balancing or synchronization of the hydraulic cylinders is ensured / realized especially when using at least two or more hydraulic units or hydraulic units. Thus, a climbing system or a composite with, for example, about 11 to 50 hydraulic cylinders / units or hydraulic units can be electronically / electrically controlled or controlled in order to realize a uniform climbing of the climbing device. An elaborate hydraulic balancing or calibration as in the prior art is eliminated.

Advantageously, at least one first hydraulic unit and one second hydraulic unit are provided, in particular numerous hydraulic units or hydraulic units, wherein between the first and the second hydraulic unit or between all hydraulic units or hydraulic units (respectively) at least one electrical connection line to the electrical and / or electronic connection and / or for electrical power supply and / or for electronic data or information transmission is arranged.

Preferably, at least one electrical and / or electronic central unit is provided for controlling at least the first and the second hydraulic unit and / or all hydraulic units or hydraulic 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 formed as a separate component / unit of the climbing device according to the invention, which is electrically and / or electronically or wired and / or wireless or by remote data / radio transmission with the / connected hydraulic units. For example, the central processing unit may be formed as a computer, notebook, laptop, PDA, smartphone or the like. Advantageously, the connection between hydraulic units or hydraulic units and / or between hydraulic units and the central unit comprises at least one transmitter and / or receiver for wireless information or data transmission between at least two hydraulic units or hydraulic units and / or between the control unit and / or central unit and / or the hydraulic units, etc. With the aid of such a radio link between two hydraulic units or hydraulic units or the control and / or central unit a particularly flexible data connection or control / monitoring of the climbing device according to the invention is possible. This reduces the cost of laying cables such as between corresponding units or between the sometimes several (dozens) meters spaced hydraulic units or hydraulic units.

In a particular embodiment of the invention, the electrical and / or electronic control unit or the addressable control unit is designed as a control unit for controlling the operating state of the hydraulic units or hydraulic units. The control unit preferably comprises an addressable interface to a digital data transmission unit. By this measure it is achieved that the hydraulic unit or hydraulic unit can be controlled or monitored / monitored when the digital data transmission unit addressed data or data with appropriate address of the hydraulic unit or hydraulic unit transmits to the addressable interface. Accordingly, the interface switches or connects the electrical energy / information of the hydraulic units or hydraulic units in an advantageous manner with a correspondingly transmitted or correct address. Preferably, a data / information transmission separate from the power supply takes place. In this case, two energy conductor elements or electrical supply cables / lines for supplying energy to the hydraulic units or hydraulic units are sufficient.

Advantageously, a plurality of hydraulic units or hydraulic units according to the invention with respect to the power supply connected in series or a single circuit for a plurality of hydraulic units or hydraulic units provided. The control or the adjustment / synchronization is realized in an advantageous manner by the addressing. This means that, for example, when several, eg 20 to 40 hydraulic units or hydraulic units a certain hydraulic unit or hydraulic unit is controlled / controlled, if the associated address, which is transmitted by means of the digital data transmission unit to the addressable interface and with an advantageous Assigned address of the specific interface or hydraulic unit or hydraulic unit matches. Accordingly, the interface switches or connects the respective hydraulic unit or the respective electric motor of the hydraulic pump with the power supply to the adjustment / extension of the piston or the vote of the To control / regulate all hydraulic cylinders.

In the event that the address transmitted by means of the data transmission unit does not coincide with the specified address of the hydraulic unit, the interface of the corresponding hydraulic unit or hydraulic units does not switch or the electric motor is operated unchanged or supplied with energy. That is, no change or adjustment / correction of the extension speed of the piston is made.

In a particular embodiment of the invention, essentially each of the hydraulic units or hydraulic units is assigned at least one address and / or one code. With the help of such addressing or codification of the individual hydraulic units or hydraulic units, a unique or advantageous assignment can be implemented. This is particularly advantageous in the case of wireless data transmission between the hydraulic units or hydraulic units.

In an advantageous variant of the invention, at least one electrical data memory for storing the operating states of at least one of the hydraulic units or hydraulic units and / or hydraulic cylinders is provided. With the aid of such an advantageous data memory, for example, statistical evaluations, inter alia, for a specific operating period such as for a mission or a construction site or, for example, a month or a year, in an advantageous manner will be realized. For example, errors, impairments, etc. of the hydraulic units or hydraulic units can be stored or determined accordingly.

Preferably, at least one display unit is provided for visually displaying the operating states of at least one of the hydraulic units or hydraulic units and / or the hydraulic cylinders. In particular, the display unit is designed as a screen. With the help of such an advantageous visual presentation, there are completely new possibilities of central monitoring or remote monitoring of several 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.

Preferably, the display unit is designed to display all hydraulic units or hydraulic units and / or data connections. Hereby advantageously an overall monitoring of all involved components or hydraulic units or hydraulic units is possible. This is particularly advantageous for a site manager, master, manager or the like, for example, the individual hydraulic units or hydraulic units and thus the individual hydraulic cylinders or the like, centrally or jointly to collect, if necessary, with the help of advantageous storage time-shifted to look at or control and / or carry out statistical calculations and present in an advantageous manner. Hereby, an optimization of the operation of the climbing phase or climbing device to be monitored according to the invention can be realized in a novel manner.

For display and / or storage and calculation of statistical evaluations or the like, in particular a computer, preferably a notebook, a so-called PDA, but also a mobile phone or other portable electronic media are of particular advantage.

Especially when using computers, notebooks, PDAs or the like, the entire operation of the climbing device or of the climbing system according to the invention advantageously comprises. For example, such electronic devices are integrated or integrated via advantageous or commercially available interfaces into the hydraulic unit or hydraulic unit. In this case, for example, so-called bus systems can be used such as USB, RS232, Ethernet, etc., but also wireless communication systems such as Bluetooth etc. According to the invention may be a complex network with several hydraulic units or hydraulic units and possibly computers, cell phones, PDA or the like be realized, which allow the display of the operating conditions of different hydraulic units or hydraulic units.

In general, a hydraulic unit or hydraulic unit may also comprise further units, such as e.g. acoustic signaling, other sensors for condition detection, etc. include. Their operating states or signals can be treated in an advantageous manner according to the above-described embodiments such as the operating states of the hydraulic units or hydraulic units or transmitted to the control unit or the central unit and possibly displayed. Hereby, further functions or controls of the hydraulic units or hydraulic units can be realized in an advantageous manner.

In principle, it is also conceivable that by means of advantageous programming, for example by means of a so-called app programming or the like, an integration for the operation of the climbing device according to the invention or new functionalities of corresponding (mobile) telecommunication devices can be realized without much effort. 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 realized, for example, by remote data transmission or Internet or the like, so that the user already existing for private reasons, for example, mobile telecommunications device (with Internet access) such as a smartphone, tablet or the like, then in addition to configure or change the Settings and / or display or monitoring / control can use inventive climbing equipment. This will be a additional functionality of the climbing device realized according to the invention. For example, the effort to monitor and / or display the climbing device or a relatively complex / larger climbing system is significantly reduced.

By a corresponding codification or modulation and / or encryption of the wireless setting information high reliability in the climbing device is realized. For example, a display / monitoring / control with a mobile telecommunication device can also be secured against unauthorized manipulation by using a password or corresponding access code.

Basically, the customer / user can make or receive the information for the configuration or adjustment of the operating parameters and / or the operation via the Internet and / or by "App" or the like and save on appropriate telecommunications equipment and then the information or settings or Advantageously, wirelessly transmits 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 aid of the (mobile) telecommunication device on the screen. For example, pressure forces, piston speeds, soft start and / or soft-stop or so-called "ramps", pause intervals or operating times and operating pauses as well as warning signals or signal lights or Beeps, esp. Whose volume, frequency or pulsating, decaying etc. and / or sound sequences or tunes or the like with the help of the advantageous telecommunications device viewed or listened to and / or set or be played and according to the invention to the climbing device be wirelessly transmitted and thus configured according to the invention or their operating parameters are set accordingly.

Preferably, at least one piston sensor is provided for detecting the position / displacement of the drive piston of the hydraulic cylinder, in particular a volume-measuring sensor or pull-wire sensor or the like. Hereby, the IstPosition of the drive piston and preferably all drive piston of all hydraulic cylinders can be determined. So can be realized in an advantageous manner with the control unit, a balance or a separate control / control of / each hydraulic cylinder or (separately) all hydraulic units or hydraulic units to a largely exact synchronization of the climbing process or the climbing device according to the invention to ensure.

Basically, any number of hydraulic units or hydraulic units can be combined with each other according to the invention, esp. All existing / required and / or even or an odd number of hydraulic units or hydraulic units. In contrast, in the prior art so-called flow divider were commonly used to operate hydraulically two cylinders with a common pump in synchronism, which thus allowed only an even use of hydraulic cylinders. The electrical / electronic balance or synchronization according to the invention is thus decisively more flexible and almost unlimited use.

In FIG. 1 is schematically shown 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 according to the invention. The hydraulic unit 1 comprises 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 comprises an electronic unit 7 or control unit esp. For control / control / regulation and monitoring of the electric motor 3 and / or a sensor 11 and / or a display / signal light 9. Preferably, the sensor 11 is formed as Wegmesssensor 11 and in the hydraulic cylinder 2 or in the cylinder housing 12, in order to detect an adjustment or extension / retraction of a piston 10 and to transmit signals / data to the electronics 7, among others.

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

However, relatively large / heavy dimensioned hydraulic units 1 can be realized / used according to the invention as a one-piece unit that may be too heavy for a person, so that these large / heavy hydraulic units 1 preferably with a lifting device such as a lift, lift, crane or the like is to be transported, esp. Between the construction sections, floors of the building, platforms of the scaffold, etc ..

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

The hydraulic unit 1 also has several electrical Plug 8 or connector 8, whereby the electrical power supply of the hydraulic unit 1 is ensured. For example, a plurality of plugs 8 are provided, on the one hand for the power supply of the electric motor 3 and / or the electronics 7 and on the other hand for the energy transfer to a second hydraulic unit 1 (see. FIG. 4 ).

Furthermore, separate electrical plugs or the like can also be provided in order to realize an electrical / electronic network or a digital bus system / network. This networking of several hydraulic units 1 can accordingly as in FIG. 4 schematically include any number of hydraulic units 1 include. The hydraulic units 1 can be connected to each other by means of electrical connection cables 20 for power supply and / or for data / information transmission / with each other and / or with a separate, central control unit 19. Especially the data / information transmission can also be realized wirelessly or by means of transmitter and receiver.

Climbing frames or rail climbing systems have long been in use, so that a comprehensive presentation and description of the climbing device according to the invention with all components and their mode of action or cooperation / workflows is largely dispensed with, since these are known in principle to those skilled.

In the present case, only the hydraulic unit 1 according to the invention and their arrangement in FIG. 3 a bit closer to be discribed. In FIG. 3 are two climbing shoes 15, 16 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 known to those skilled locking system, whereby its direction of movement is predefined. A method / adjustment in the opposite direction is not possible without influencing the climbing shoes 15, 16.

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

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