Abstract: A crane hook assembly having a hook weight arrangement serves for applying a tension load to a rope (2). The rope can be wound onto or off a rope drum on a crane and lifts or lowers the crane hook (4). The hook weight arrangement (1*) includes a hook weight body (3) connected to the rope (2) and an additional weight (26) which is attachable thereto. The rope (2) is guided through an opening (10, 6) in the hook weight body (3, 3*), and the crane hook (4) is attached on the bottom end (20) of the hook weight body (3, 3*).

Abstract: A control device for operating a machine has a control unit with at least one actuating unit to which actuators and sensors are connected for operating the machine. The control unit has a bus line for transmitting control commands from an operating part to the actuating device. A plug connection between the operating part and the control unit is provided. A monitoring unit monitors an operating signal of the operating part. The monitoring unit triggers a safety function when the operating signal that is a heartbeat of the operating part is absent. Operating states of the operating part are monitored by the monitoring unit. An output signal of the monitoring unit is evaluated in that, when the operating part is switched on, the heartbeat is processed and, when the operating part is switched off, the absence of the heartbeat is ignored.

Abstract: A rope winch has at least one bearing support and a rope drum supported on the at least one bearing support so as to be rotatable about a drive axis. A drive motor and a gear connected to the drive motor are provided, wherein the drive motor drives the rope drum about the drive axis through the gear. At least one sensor that senses a load acting on the rope drum is provided. An exchangeably secured component that is exchangeable without dismounting the at least one bearing support is provided. The at least one sensor is arranged on the exchangeably secured component.

Abstract: In a method for configuring at least one mobile operating unit of at least one control, wherein the at least one operating unit is detachably connectable to the at least one control, wherein the at least one operating unit has a display, a memory, and an input device, the configuration information, required for configuring the at least one operating unit, is transmitted from the at least one control to the at least one operating unit at the time of connecting the at least one operating unit to the at least one control. The configuration information is then utilized in the at least one operating unit. The configuration information saved in the memory can be overwritten by new configuration information received from the control.

Abstract: A rope guide for a rope of a winch of a motor vehicle has a fairlead for guiding the rope and a fastening part for securing the rope guide to the motor vehicle. The fairlead and the fastening part are combined to a mountable module. The mountable module is configured to be exchangeably secured on a mount attached to the motor vehicle. The mount is a towing device having least one towing hook. The fastening part is configured to cover the mount.

Abstract: A cable drum, having a substantially cylindrical drum body with drum walls arranged at its axial ends and a groove arrangement arranged on the drum body, enables winding of a cable in a rotational direction clockwise as well as counter-clockwise thereto. The groove arrangement has parallel areas in which the grooves are parallel to the circumferential direction and incline areas in which the grooves are slanted at an angle relative to the circumferential direction of the drum body. All grooves in the parallel areas have identical groove width. The grooves in the incline areas cross one another.
