Abstract

PURPOSE: To realize safe, convenient, and easy loading and unloading operation by outputting a control signal corresponding to the operation of a loading and unloading operation means when a seating signal or a signal from an auxiliary switch is continuously input for a predetermined period of time. CONSTITUTION: When a seating signal from a seat switch 19 or an auxiliary operation signal from an auxiliary switch 20 making it operable even in a non-seated condition is continuously input for a predetermined period of time, a controller 18 outputs a control signal corresponding to the operation of a loading and unloading operation lever 17 to electromagnetic opening and closing valves 14A, 14B to drive and control a hydraulic actuator. Here, when the operation lever 17 is operated before the seating signal or the auxiliary operation signal is output and the seating signal or the auxiliary operation signal is continuously output for a predetermined period of time on the halfway, a CPU 33 outputs a control signal at a low level initially and increases its level gradually up to an operation level after that. Consequently, it is possible to improve the safety and operability of loading and unloading works.
