Description

Forklift truck

Technical Field

The invention relates to the field of engineering vehicles, in particular to a forklift.

Background

The forklift is widely used for loading, unloading, stacking and short-distance transportation operation of goods, plays a very important role in a logistics system of an enterprise, and is a masterforce force in material handling equipment. However, the fork frame of the existing forklift can only lift along the height direction of the forklift and cannot move along the front-back direction of the forklift, so that the fork frame can only adjust the distance between the forklift and the goods taking point or the goods unloading point by means of the motion of the wheels of the forklift when the goods are taken or unloaded, the distance between the forklift and the goods taking point or the goods unloading point needs to be accurately mastered when the forklift stops, and otherwise, the forklift needs to be frequently moved due to too close stopping or too far stopping of the forklift. Meanwhile, in the case of narrow unloading points or goods taking points, the forklift can not stop too close, so that the forklift is very easy to get inconvenient to unload and take goods due to too long distance between the forklift and the goods taking points or the unloading points.

Therefore, how to design a forklift with a fork capable of moving in the front-rear direction of the forklift becomes a problem to be solved urgently at present.
