Abstract

PURPOSE: To improve the safety and operability of loading and unloading works by outputting a control signal at a low level initially and increasing its level gradually when a seating signal or an auxiliary operation signal is input in a controller during the operation of a loading and unloading operation means. 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 input, 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. In this case, when the operation lever 17 is operated before the seating signal or the auxiliary operation signal is input and the seating signal or the auxiliary operation signal is input during the operation, a CPU 33 outputs a control signal at a low level initially and increases its level gradually up to an operation level. Consequently, it is possible to perform loading and unloading operation safely, conveniently, and easily.
