This application is based on a Chinese patent application with an application number of 201910219062.4 and an application date of March 21, 2019, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby incorporated by reference into this application.

Technical field

The application relates to the field of engineering vehicles, and specifically to a forklift.

Background technique

Forklifts are widely used for cargo loading and unloading, stacking and short-distance transportation operations. They play a very important role in the enterprise's logistics system and are the main force in material handling equipment. However, at present, the forklift can only adjust the position of the goods through the fork frame when transporting goods, and cannot realize the rotation of the goods on the horizontal plane. This makes it impossible to adjust the center of gravity of the goods on the forklift, so that the goods cannot be moved along the length of the goods. The vehicle body is placed in the front and rear direction, which will easily cause the center of gravity of the goods to be unstable, and therefore, the risk of overturning is extremely likely to occur when the forklift transports the goods.

Therefore, how to design a forklift capable of rotating goods in a horizontal plane has become an urgent problem to be solved at present.
