INDUSTRIAL VEHICULAR DATA SETTING DEVICE AND INDUSTRIAL VEHICLE

摘要

PROBLEM TO BE SOLVED: To set up controlling data (maps) capable of positional control over material handling equipment at high accuracy in a simple manner, without being affected by any possible assembling variations in the material handling equipment and sensors. SOLUTION: A controller installed in a forklift truck controls the current value of a solenoid valve installed in a hydraulic circuit and then performs its forward tilting regulation control which stops a mast at a maximum allowable forward tilting angle. A checker for setting up a map in use of this forward tilting regulation control is connected to this controller. Those of [data showing relations between duty load M and maximum allowable forward tilting angle, such as set values (a), (b) and so on conformed to car type] necessary for making up the map, are stored in a read-only memory. When a setting operation part provided in the mast is operated in a state that this mast is accurately tilted at a tilt angle of '2 deg.', a central processing unit OPU uses the detected value of a tilt angle sensor at a time when this setting operation part is operated as the detected value when the mast is in the tilt anglt of '', and thus the map is automatically calculated (automatic formation) with the data stored in the read-only memory ROM.
