Method and system for horizontally controlling a fork for a fork lift truck

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