DYNAMIC LIFT-OFF CONTROL DEVICE, AND CRANE

摘要

A dynamic lift-off control device that is mounted on a crane having a boom and a winch for winding a wire rope and that controls dynamic lift-off of a suspended load, wherein: the dynamic lift-off control device comprises a load detection unit that detects a load acting on the boom, and a control unit that controls a winding action of the winch and a hoisting action of the boom; and the control unit controls the hoisting of the boom by using a control signal, which is generated on the basis of the change over time in the value detected by the load detection unit and to which is applied a filter for dampening a frequency component in a prescribed range, to suppress swaying of the suspended load.
