Embodiment Construction

[0037] from figure 1 The work machine 10 according to the invention is designed as a crawler crane, which includes a mobile carrier 12 . The vehicle 12 includes a tracked undercarriage 14 on which a superstructure 15 is rotatably mounted. A mast 16 (also referred to as a boom) is mounted on the superstructure 15 so as to be pivotable about a horizontal pivot axis. For pivoting the mast 16 , a holding bracket 26 , a support bracket 28 and a cable positioning mechanism 27 are provided on the superstructure 15 in a manner known in principle.

[0038] At least one support cable 20 is guided from the superstructure 15 over the mast head 18 of the mast 16, on which cable is suspended a working element 30, which in the illustrated embodiment is designed for soil compaction The impact weight 32. In the described embodiment, the support cables 20 are adjustably driven in the superstructure 15 by means of a double winch arrangement, as is known in principle from the prior art. In or...

Abstract

The invention relates to a working machine, comprising a mast having a mast head, a support cable which is guided along the mast, over the mast head, a cable winch comprising a rotatably mounted winding drum to which the support cable is attached for winding up and unwinding, a work element which is arranged on the support cable for vertical movement, and a control unit, by means of which the cable winch can be operated in an unwinding mode, for unwinding the support cable from the winding drum, in which mode the work element is lowered, on the support cable, as far as a base surface. According to the invention, a cable contact pressure means comprising at least one contact pressure element is provided, which element can be adjusted into a contact pressure position by the control unit, bymeans of an actuating member, in order to counteract a cable oscillation of the support cable when the base surface is struck, in which contact pressure position the contact pressure element rests onthe support cable at a contact pressure force.

Description

technical field [0001] The invention relates to a work machine, in particular a construction machine, according to the preamble of claim 1, comprising: a mast with a mast head; a support cable guided along the mast via the mast head; a cable winch comprising a rotatable A mounted winding drum to which a support cable is attached for winding up and unwinding; a working element arranged on the support cable for the purpose of vertical movement; and a control unit, by means of In the control unit, the cable winch can be operated in an unwinding mode for unwinding the supporting cable from the winding drum, in which unwinding mode the working element is lowered on the supporting cable up to the substrate surface. [0002] The invention also relates to a method for operating such a work machine according to claim 12 . Background technique [0003] A work machine of the type in question is obtained, for example, from European patent 3144260 B1. In this case, the support cables a...
