Abstract

A storage stores at least one piece of registered correction data including a plurality of registered values associated with a plurality of section angle ranges. A controller executes parallel winch control of causing a derricking winch and a hoisting winch to operate. The controller specifies a reference target value corresponding to a derricking angle, from the plurality of registered values. In a correction period corresponding to a point of time at which a correction operation is detected, the controller corrects the reference target value used for deriving an operation speed of the hoisting winch in the parallel winch control, in accordance with a specified value specified by the correction operation. The controller updates data of the reference target value corresponding to the correction period to data corrected with the specified value.
