Claim 0:
1. A crane comprising:
a operable functional unit;
an actuator for driving the operable functional unit;
a generation unit that, in control of causing the operable functional unit to automatically stop, generates a first control signal including a first deceleration signal section including a control signal for decelerating a speed of the operable functional unit from a first speed to a second speed and a first constant-speed signal section including a control signal for maintaining the speed of the operable functional unit at the second speed;
a filter unit for filtering at least the first deceleration signal section in the first control signal to generate a second control signal; and
a control unit that controls the actuator so as to decelerate the operable functional unit on the basis of the second control signal, then controls the actuator so as to maintain the speed of the operable functional unit at the second speed, and controls the actuator so as to zero the speed of the operable functional unit in a case where it is determined that a load suspended from the crane moves to a location satisfying a prescribed condition.
