Background

Forklifts have an irreplaceable role in modern logistics technology. The main function of fork truck is for stacking and shifting the goods, and fork truck when goods stack, the jack-up system often need to accomplish preceding, hypsokinesis action and side and move the action. The lifting system is driven to tilt forwards and backwards through the reciprocating motion of the extension and retraction of a piston rod of a tilting oil cylinder connected with the lifting system. When the goods are lifted to the highest point, the forward-tilting hoisting system can greatly enlarge the distance between the center of gravity of the goods and the center of a front wheel of the forklift (the center of the front wheel of the forklift is a balanced fulcrum of the whole forklift), so that the stability of the whole forklift is reduced. In order to complete the movement of the lifting system for moving the goods laterally, a side shifter is generally assembled, and the fork can be moved leftwards and rightwards by the movement of the side shifter, namely the forward and backward tilting movement and the side shifting movement of the lifting system are completed by two devices.
