Definitions

  • the present invention relates to a guying system for guying a mobile crane telescopic boom according to the preamble of claim 1, a mobile crane with such a guying system, an assembly device for such a guying system and a method for self-assembly of the guy supports of such a guying system.
  • V-shaped guy supports which are pivotably mounted on the articulation section of the telescopic boom (so-called Y guying), in order to increase the load capacity and lateral stability.
  • the guy supports also referred to as TY frames
  • TY frames are typically pivotable about two axes, so that they can be pivoted from an assembly position resting against the telescopic boom into their V-shaped operating position.
  • the guy supports In order to comply with the prescribed axle loads, the guy supports usually have to be moved separately for transport on public roads and mounted on the boom at the place of use.
  • the guy supports can be lifted, for example, by means of an auxiliary crane and placed in a mounting position on the telescopic boom.
  • this method is relatively complex and time-consuming, since several strokes and individual steps are necessary.
  • the present invention is therefore based on the object of simplifying the assembly and disassembly of such a telescopic boom guying. This should be able to be carried out by the mobile crane itself and in as few steps as possible.
  • a guying system for guying a telescopic boom of a mobile crane which comprises two guying supports that can be mounted individually on the telescopic boom.
  • the guy supports are therefore not attached or mounted together as a unit, but each individually via appropriate connecting means on the telescopic boom. This results in a lower weight than with solutions in which the guy supports are mounted on the telescopic boom as a unit connected, for example, via a mounting frame.
  • the guying system also includes an assembly device for self-assembly of the guy supports on the telescopic boom and for storing the guy supports during transport.
  • the assembly device comprises two frame parts, on each of which a guy support can be placed or stored and can be fixed in a detachable manner.
  • the mounting device can optionally also have an adjustment unit include, by means of which the frame parts and thus the guy supports fixed on the frame parts are movable relative to each other.
  • the assembly device fulfills a dual function. On the one hand, it represents a transport device for the secure transport of the guy supports on an external transport vehicle. On the other hand, it enables easy self-assembly of the guy supports, since they can be positioned on the mobile crane in a single lift together with the assembly device, rather than in several individual strokes. For this purpose, the guy supports do not have to be moved relative to the assembly device or removed from it, but they can remain in a fixed position on the assembly device. The transport and assembly device are therefore integrated in one unit.
  • the optional division of the assembly device according to the invention into mutually movable frame parts also makes it possible to position the two guy supports relative to one another and thus to change the overall width of the assembly device.
  • the two guy supports for mounting on the telescopic boom must be at a certain distance from each other so that the telescopic boom can be lowered between the guy supports from above.
  • the resulting overall width of the assembly device may exceed the maximum width permitted for public road transport.
  • the frame parts can now be moved relative to one another by means of the adjusting unit in such a way that the assembly device achieves a smaller transport width suitable for public road transport.
  • the mounting device can be designed as a frame or as a mounting frame.
  • the assembly device is preferably constructed symmetrically, with the frame parts being able to be moved perpendicularly to the axis of symmetry by means of the adjusting unit.
  • the mounting device cannot be mounted on the telescopic boom. So there are no fasteners provided, via which the mounting device can be attached to the telescopic boom.
  • the assembly device is used exclusively for correct positioning relative to the telescopic boom and for providing storage areas for the guy supports.
  • the guy supports are mounted individually and directly on the telescopic boom and then the connection between the guy supports and the assembly device is released.
  • the assembly device does not contribute to the total weight of the guyed telescopic boom, which increases the maximum load capacity.
  • the assembly device can then be removed from the mobile crane or remain on the mobile crane while the crane is in operation.
  • the assembly device can be moved from an assembly position into a transport position and vice versa by means of the adjusting unit.
  • the telescopic boom In the assembly position, the telescopic boom can be retracted or lowered from above between the spaced-apart frame parts, so that it is aligned essentially parallel to the guy supports placed on the frame parts.
  • the area between the frame parts thus represents, as it were, an upwardly open receiving area for the telescopic boom.
  • the assembly device In the transport position, the assembly device has a smaller overall width than in the assembly position. As a result, the overall width of the assembly device for road transport can be reduced so that the permissible maximum width is not exceeded and special transport is therefore not required.
  • the extension of the frame parts i.e. the movement of the assembly device from the transport to the assembly position and vice versa, can take place on the transport vehicle or in a state in which the assembly device is attached to the mobile crane.
  • the frame parts can be moved linearly, ie in a translatory manner.
  • the frame parts are preferably included movable along a direction which is perpendicular to the longitudinal axes of the guy supports when they are mounted or fixed on the frame parts.
  • the frame parts can thus be moved towards one another and away from one another by means of the adjustment unit, in particular within a common horizontal plane.
  • the frame parts move along sweeping curves or arches or that they can be moved linearly obliquely up/down (ie not within a common plane). In this case, it merely has to be ensured that the overall width of the mounting device is less in the transport position than in the mounting position.
  • the assembly device comprises at least one guide means, which is in particular a guide rail or guide rod, along which the frame parts can be displaced.
  • the guide means preferably runs perpendicularly to the longitudinal axes of the guy supports when they are mounted or fixed on the frame parts.
  • One or more guide means can be provided per frame part.
  • the end positions of the frame parts during their movements along the guide means i.e. the assembly and transport positions
  • the at least one guide means can have a correspondingly non-linear (e.g. curved or curved) shape.
  • the frame parts can be guided along such a path by means of a corresponding mechanism, for example using a link guide.
  • a linear movement of the frame parts is preferred, since this allows a particularly simple construction to be implemented.
  • the adjustment unit has at least one hydraulically, electrically or mechanically actuatable actuator includes, by means of which the frame parts are mutually displaceable.
  • the actuator can be a linear or radial drive, for example.
  • the actuator can preferably be connected to an energy supply system of the mobile crane.
  • a hydraulically actuable actuator eg a hydraulic cylinder
  • the hydraulic actuator can be adjusted manually by means of a hand pump or in some other way.
  • An electrically actuable actuator can be connected to the mobile crane via appropriate cables.
  • the at least one actuator can be a hydraulic cylinder. This can be arranged parallel to the direction of movement of the frame parts. Alternatively, the at least one hydraulic cylinder can be arranged perpendicularly to the direction of movement of the frame parts and move them via an adjustment mechanism, for example a linkage. Other arrangements of the at least one hydraulic cylinder are also conceivable here.
  • the maximum stroke of the at least one hydraulic cylinder can form the end stop at which the mounting device is in the mounting position.
  • the adjustment unit can comprise a gear or rack and pinion drive and/or a cable pull mechanism.
  • the mounting device has fastening means for detachable fastening to the mobile crane, in particular to an undercarriage of the mobile crane.
  • the undercarriage can have a mounting surface with appropriate fastening means. This can be located in the area of the driver's cab.
  • the assembly device is lifted to the assembly surface on the mobile crane and fastened there via the fastening means, in particular bolted.
  • the fastening means are preferably located in the lower area of the assembly device.
  • positioning aids can be provided on the mobile crane and/or on the assembly device, which facilitate the assembly or alignment of the assembly device on the mobile crane.
  • the assembly device can now either be removed from the mobile crane again or remain on the mobile crane while the crane is in use. It is advantageous for the mounting device to remain on the mobile crane during use, since it can then be used to store the guy supports mounted on the telescopic boom when the mobile crane travels to a construction site. There is no need for additional transport safety devices because the guy supports on both sides of the telescopic boom then lie on the frame parts and are supported on them during the journey. This prevents the connections between the telescopic boom and guy supports from being overloaded due to impacts when the mobile crane is being moved.
  • the guy supports attached to the telescopic boom can be temporarily fixed to the frame parts for a trip to the construction site.
  • the frame parts have supports on which the guy supports can be placed or stowed and releasably fixed, the supports being designed such that the longitudinal axes of the guy supports are aligned parallel to one another in the stored or fixed state.
  • the supports can be designed in such a way that the guy supports remain in position or do not slip due to their weight.
  • positioning aids can be provided which enable or facilitate correct positioning or placement of the guy supports on the supports.
  • the assembly device comprises fixing means, by means of which the guy supports can be detachably fixed to the frame parts.
  • the fixing means can be lashing means that enable quick and easy fixing or lashing of the guy supports.
  • the guy supports can be bolted to the frame parts.
  • the fixing means can be arranged on the frame parts.
  • the assembly device preferably has a plurality of stop elements for connection to a stop or load-carrying means of the mobile crane, via which the assembly device can be lifted.
  • the stop elements are preferably arranged in such a way that the mounting device aligns itself horizontally both with and without guy supports attached to it during the lift.
  • the mounting device can have fastening means for fastening or fixing to a transport vehicle. This can also be a matter of lashings, which enable the assembly device to be quickly attached/detached to/from the transport vehicle.
  • the invention further relates to an assembly device for the guying system according to the invention for self-assembly of the guying supports on the telescopic boom and for storing the guying supports during transport.
  • the mounting device can include fixing means for attaching or fixing the guy supports to the frame parts.
  • fastening means for fastening or fixing the assembly device on a transport vehicle can be part of the assembly device.
  • the present invention relates to a mobile crane with a guying system according to the invention.
  • the mobile crane also includes a mobile undercarriage, an uppercarriage rotatably mounted on the undercarriage, and a telescopic boom mounted on the uppercarriage in a pivotable or luffing manner.
  • the telescopic boom comprises a linkage section which is articulated on the upper carriage so that it can pivot in particular about a horizontal axis and one or more telescopic sections which are mounted displaceably therein.
  • the undercarriage preferably includes a wheeled chassis so that it can be moved on public roads.
  • the anchoring system according to the invention or the assembly device according to the invention can also be used in a mobile crane with a crawler chassis.
  • the mobile crane can also have a support device with preferably a plurality of extendable and/or pivotable supports. To lift the assembly device from the transport vehicle to the assembly area on the mobile crane, it may be necessary to support the mobile crane using the support device.
  • the mobile crane also preferably has an upper carriage ballast.
  • the guy supports can preferably be pivotably mounted, in particular bolted, on a collar of the pivot section.
  • the guy supports are also preferably each pivotable about two axes, in particular by means of a hydraulic cylinder.
  • the undercarriage has fastening means, via which the mounting device can be fastened to it. These are preferably arranged in such a way that the fastening elements on the collar of the pivot section are in the region of corresponding fastening elements on the guy supports after the telescopic boom has been lowered between the frame parts of the assembly device in the assembly position.
  • the mounting device can preferably be mounted on the mobile crane via the fastening means in such a way that it can remain on the mobile crane during crane operation and the telescopic boom can be placed or supported on the mounting device via the installed guy supports.
  • the transport vehicle can be a tractor with a semi-trailer with a corresponding transport surface on which the assembly device can be fixed.
  • the transport vehicle can be a tractor with a semi-trailer with a corresponding transport surface on which the assembly device can be fixed.
  • the dismantling of the guy supports of the guying system according to the invention from the telescopic boom is essentially carried out by performing the aforementioned steps in reverse order, i.e. luffing the telescopic boom between the frame parts with the guy supports attached to the side so that the guy supports rest on corresponding supports of the frame parts (the assembly device for this is in the assembly position), fixing the guy supports on the frame parts, loosening the connection, in particular the bolting, of the guy supports with the telescopic boom, luffing up the telescopic boom, loosening the fastening of the assembly device on the mobile crane, lifting the assembly device by the mobile crane and placing the assembly device on a transport vehicle, where it can then be fixed.
  • the assembly device is moved by means of the adjustment unit from a transport position with a reduced overall width to an assembly position in which the telescopic boom can be retracted between the frame parts from above by rocking, with the telescopic boom preferably being in the Is aligned substantially parallel to the guy supports mounted or fixed on the assembly device.
  • the assembly device is transferred from the assembly position to the transport position, so that the maximum permissible overall width is maintained during transport.
  • the assembly device remains on the undercarriage after the assembly of the guy supports during crane operation, so that the telescopic boom can be placed or supported on the assembly device via the guy supports attached to it in order to move the mobile crane at the place of use.
  • the Figures 1a and 1b show the mounting device 10 of the guying system according to the invention according to a preferred embodiment in perspective views, the mounting device 10 in FIG Figure 1a in the transport position and in the Figure 1b shown in the assembled position.

  • the hydraulic cylinder 24 is on a central position along the fixture
  • the extension and retraction movement of the hydraulic cylinder 24 is transmitted via a linkage mechanism to a synchronized movement of the frame parts 12, 13 running transversely thereto.
  • the linkage mechanism comprises two rods 26 pivotally attached to each of the frame parts 12, 13, which are also pivotally connected to the piston rod of the hydraulic cylinder 24 at different axial positions.
  • the two frame parts 12, 13 are at a minimum distance from one another and are in the transport position (cf. Figure 1a ).
  • the frame parts 12, 13 are at their maximum distance from one another, so that the assembly device 10 is in the assembly position (cf. Figure 1b ).

  • the mounting device 10 is in the transport position, in which the frame parts 12, 13 and thus the guy supports 40 are at a minimum distance (or at least a smaller distance than in the mounting position) from one another.
  • the assembly device 10 and the guy supports 40 fastened to it do not protrude laterally beyond the semi-trailer, so that the maximum permissible transport width (eg 2.5 m) for public road traffic is observed.
  • FIG. 5-8 1 shows an exemplary embodiment of a mobile crane 1 with the guying system according to the invention in different positions or during different steps of the assembly method according to the invention, each in a side view.
  • the mobile crane 1 comprises an undercarriage 2 with a wheeled chassis, a driver's cab 5 and a support device 7, an uppercarriage 3 mounted on the undercarriage 2 so that it can rotate about a vertical axis, and an uppercarriage on the uppercarriage that can be pivoted or luffed about a horizontal axis by means of one or more luffing cylinders 8 3 mounted telescopic boom 4.

  • the mounting device 10 can now be moved from the transport position to the mounting position by means of the adjustment unit 20 by the frame parts 12, 13 being moved apart together with the guy supports 40.
  • this step can already take place on the transport vehicle 60 after arrival at the place of use and before the hub. This is necessary because the distance between the guy supports 40 in the transport position is too small for the telescopic boom 4 to be able to be lowered between the frame parts 12, 13 or guy supports 40.

  • the guy supports 40 are in their guyed position aligned essentially perpendicularly to the longitudinal axis of the telescopic boom 4 and—which cannot be seen in this view—are spread out in a V-shape (Y guying).
  • the guy supports 40 are connected to the superstructure 3 via first guying means (usually guy rods), while the boom head 4c is connected to the guy supports 40 via second guying means 44 in the form of guy ropes, which are guided over deflection rollers at the ends of the guy supports 40.
  • the mounting device 10 remains on the undercarriage 2 while the crane is being used and can serve as a support device when the mobile crane 1 is moved on the construction site.
  • the guy supports 40 are placed or folded back onto the telescopic boom 4 and the telescopic boom 4 is luffed so that the guy supports 40 rest on the supports 14 , 15 of the frame parts 12 , 13 .
  • the boom 4 is thus supported on the assembly device 10 . This protects the connections between the guy supports 40 and the pivot section 4a from being overloaded during the process.
  • the telescopic boom 4 When dismantling, the telescopic boom 4 automatically repositions the guy supports 40 in the correct position and setting on the supports 14, 15 of the frame parts 12, 13, so that the fixing with the assembly device 10 can be easily restored. These positions of the guy supports 40 remain unchangeable via the fixing means 18 even during renewed transport secured, so that the guy supports 40 have the correct position for the assembly on the frame parts 12, 13 during the next assembly. The bolting between guy supports 40 and pivot section 4a can therefore be easily restored.
  • the assembly device 10 is generally not attached to the mobile crane 1 while it is being moved on public roads. This can only be kept in countries with higher permissible axle loads on the mobile crane 1 on public roads.
