DYNAMIC LIFT-OFF CONTROL DEVICE, AND CRANE

摘要

The present invention provides a dynamic lift-off control device and a crane with which it is possible to quickly perform dynamic lift-off of a suspended load while suppressing vibration of the load. This dynamic lift-off control device D comprises: a boom (14); a winch (13); a load weight measurement means (22); and a controller (40) serving as a control unit, the controller (40) controlling operations of the boom (14) and the winch (13), deriving, when performing dynamic lift-off of the suspended load by hoisting the winch (13), an amount of change in a derricking angle of the boom (14) on the basis of the time change in the measured load weight, and raising the boom (14) so as to compensate for the amount of change.
