The invention relates to a construction machine, in particular a drilling device, comprising a mast along which a tool is movably mounted, the tool being suspended on a rope which can be actuated by means of a rope winch for raising and lowering the tool, the rope winch is driven in a drive mode by an electric motor as a winch drive, the electric motor being designed to operate in a recovery mode in which the electric motor generates electrical energy preferably when the tool is lowered and outputs the electrical energy to an energy store; and a control unit which is designed to actuate the electric motor as a function of a setpoint value that can be specified in such a way that the cable is tensioned both in a drive mode of the electric motor and in a take-up mode of the electric motor.
本发明涉及一种工程机械、尤其是钻孔设备,其带有:桅杆,工具沿着所述桅杆可运动地支承,其中,所述工具悬挂在绳索处,所述绳索能够借助绳索卷扬机操纵以用于工具的升高和下降,绳索卷扬机由作为卷扬机驱动器的电动马达在驱动模式下驱动,其中,所述电动马达构造成用于在回收模式下运行,在该回收模式下,所述电动马达优选在所述工具下降时产生电能并输出到能量蓄存器处;以及控制器,所述控制器构造成用于根据可预设的理论值如此操控所述电动马达,使得所述绳索不仅在所述电动马达的驱动模式下而且在所述电动马达的回收模式下都张紧。
