Lift mechanism controller and control method for industrial vehicles

摘要

A lift vehicle (1) and a method for initializing a controller for controlling a lifting mechanism of lift vehicle (1). The controller (40) controls the maximum forward tilt angle of a mast (4) by controlling a solenoid (25a) of a hydraulic circuit. The controller (40) employs a stored map or equation that defines a relationship between the forward tilt limit and another parameter. When the mast (4) is tilted at two degrees, a CPU (54) reads the detection value of a tilt angle sensor (44) and sets it as a reference value. The reference value is used to calibrate the controller(40). The same function information can be used for many types of lift vehicles by selecting the appropriate control ranges for each vehicle. <IMAGE>
