Embodiment Construction

[0047] 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.

[0048] 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 work machine comprising: a mast having a mast head; a support cable guided along the mast over the mast head; a cable winch including a rotatably mounted winding drum, the support cable being attached to the reel a winding drum for winding up and unwinding; a working 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 unwinding mode for rewinding from The winding drum unwinds the support cable, in which unwinding mode the working element is lowered on the support cable up to the substrate surface. According to the invention there is provided a cable contact pressure device comprising at least one contact pressure element which can be adjusted by a control unit by means of an actuating member into a contact pressure position in order to counteract cable vibrations of the supporting cable when the substrate surface is impacted , in said contact pressure position, the contact pressure element is resting on the support cable with a contact pressure.

Description

technical field [0001] The invention relates to a work machine, in particular a construction machine, comprising: a mast with a mast head; a support cable guided along the mast via the mast head; a cable winch comprising a rotatably mounted winding drum, the support cable being attached to said winding drum for winding up and unwinding; a working element, which is arranged on the support cable for the purpose of vertical movement; and a control unit, by means of which the cable winch can Operating in an unwinding mode for unwinding the support cable from the winding drum, in which unwind mode the working element is lowered on the support cable up to the substrate surface. [0002] The invention also relates to a method for operating such a work machine. 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 are guided over the mast head on the mast in order to raise an...
