Abstract
A method and system for horizontally controlling a fork for a fork lift truck to be positioned at a position parallel with respect to the ground, according to the loads mounted on the fork. The target backward tilting angle of the upright is previously determined as a function of the load on the fork and stored in a memory of a microcomputer. Therefore, the microcomputer outputs an upright forward/backward tilting operation command signals to a tilt servo mechanism on the basis of signals outputted from a load sensor and a potentiometer to detect upright tilt angles. The tilt servo mechanism according to the present invention can adjust and stop the upright at a target backward tilting angle at a low speed without applying a shock to the load.
