Definitions
- the invention relates to a device for bracing a superlift device of a telescopic crane, in particular a mobile crane, according to the preamble of patent claim 1.
- a telescopic crane is usually equipped with a main boom that can be raised and lowered on the superstructure or the like and has at least two telescopic shots.
- a telescopic crane is usually equipped with a main boom that can be raised and lowered on the superstructure or the like and has at least two telescopic shots.
- a guy stand is arranged on the base box of the main boom, with a deflection roller attached to its free end.
- the guying is usually carried out in the form of guy ropes for the superlift device via this pulley.
- the free end of the guying is preferably on the main boom
- Headpiece of the innermost shot or attached to the penultimate shot (DE 196 06 109 A1). This known type of fastening leads to unfavorable force and torque relationships in the system of the main boom extension and superlift device and thus reduces the lifting capacities.
- the object of the invention is to provide a device for bracing a superlift device of a telescopic crane, in particular a mobile crane, with which higher loads can be achieved with otherwise the same dimensions.
- connection point between two elements of the jib is located.
- the auxiliary boom has a plurality of lattice mast elements that can be connected to one another. The desired effect of relieving the load on the main boom is only achieved if the distance between the start of the rigid auxiliary boom and the attachment point for the guying is at most half
- the length of the rigid jib is.
- Intermediate link consisting of at least one tie rod, the pivot point of the unwinding being formed by the direct connection of the lattice tip to the head piece of the auxiliary boom.
- Figure 1 is a schematic diagram of a first embodiment
- FIG 1 a device according to the invention for bracing a superlift device of a telescope crane that is already fully telescoped is shown as a basic diagram. This has a main boom 1, a basic box 2 and in this example four telescopic sections 3-6. At the head 7 of the innermost shot 6 is rigid
- the auxiliary boom 8 is composed of a plurality of lattice mast elements 9-14.
- a head roller 15 is provided, over which the hoisting rope 16 is guided.
- a guy stand 17 is arranged on the base box 2, at the free end of which a deflection roller 18 is attached.
- the guying which preferably consists of two or more guy ropes 19 (only one can be seen here), is guided over this deflection roller 18.
- the upper free end of the guying 19 is not attached to the main boom 1, but to the auxiliary boom 8.
- the attachment point 20 is preferably located at the connection point between two lattice mast elements 9, 10. The connection point results in stiffening, so that the forces can be introduced into the bracing 19 without problems.
- FIGS. 2 and 3 show a variant of the exemplary embodiment in FIG. 1, the same reference numerals being chosen for the same parts.
- an angle formation is provided on the head piece of the auxiliary boom 8
