REMOTE-CONTROLLED CRANE

摘要

The present disclosure concerns a crane, in particular a tower crane, telescopic boom crane, harbour crane and the like, with a load hook that can be raised or lowered via movable crane elements, and moved within a crane working area by operating drive units associated with the crane elements. The crane is provided with a control unit with input means to control the drive units. According to the present disclosure, the crane uses a mobile portable target signal transmitter that can be variably positioned in the crane working area, and positioning means for automatically determining the current position of the target signal transmitter relative to the load hook and/or a crane element, and target control means for automatically controlling the drive units in response to a signal from the positioning means, such that the load hook is automatically moved to the mobile target signal transmitter.

主权项

1. A crane, comprising:
a load hook; movable crane elements for raising or lowering the crane within a crane working area via operating of associated drive units; and a control unit with an input device, a mobile portable target signal transmitter, a positioning device, and a target controller, the control unit including computer-readable instructions stored on non-transitory memory for: controlling the drive units based on operator input received at the input device; variably positioning the mobile portable target signal transmitter within the crane working area; determining, via the positioning device, a current position of the target signal transmitter relative to the load hook and/or one of the moveable crane elements; and automatically controlling the drive units via the target controller in response to a signal from the positioning device such that the load hook is automatically moved to the mobile target signal transmitter.
