Abstract

PURPOSE:To enable control of an elevator to changeover from a controller to the second control circuit constituted so as to be controllable only by manual operation and prevent the vertical movement of a working machine by operation other than the manual control if the ground height of the working machine is higher than the set changeover height. CONSTITUTION:If sensed values of an elevation sensor for sensing the ground height of a working machine (B) interlocked with lift arms is higher than the set changeover height, a controller is automatically changed over from a controller to the second controlling circuit. Thereby the controller is changed over to a state in which the elevator 19 is directly controlled by manual operation without passing through the controller.
