COUNTERWEIGHT TRUCK CONTROLLING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve work efficiency of a crane by suppressing an increase of a turning radius of a wheel in turning and travelling a counterweight truck.

SOLUTION: The counterweight truck controlling device 1 includes a steering actuator 50 which controls a steering angle θ of the wheel 40, and a control means 80 which controls the steering actuator 50. The control means 80 includes a turning direction input means 81 in which a signal for determining a turning direction of an upper body 20 is input. The control means 80 controls the steering actuator 50 so that the wheel 40 (a front side in a longitudinal direction) turns inside from a tangent L1 of a turning orbit C of the wheel 40 in a position of the wheel 40 in plane view.
