[0002] An electric forklift is a forklift that uses electricity to operate. Most of them work on batteries. A battery is a type of battery that can store limited electrical energy and use it in a suitable place. Its working principle is to convert chemical energy into electrical energy. This type of battery is installed in the battery of an electric forklift.

[0003] Electric forklifts are easy to operate and flexible, and the operating intensity of their operators is much lighter than that of internal combustion forklifts. Their electric steering system, acceleration control system, hydraulic control system and braking system are all controlled by electrical signals, which greatly reduces the labor intensity of operators. This is very helpful in improving their work efficiency and accuracy.

[0004] However, the existing electric forklift lifting device is only a one-stage type, but a platform needs to be set up when forking higher goods. After the forking of the higher goods is completed, the platform needs to be removed and the lower goods need to be forked. This method of transporting goods is cumbersome, time-consuming and labor-intensive, and has low transportation efficiency. In addition, for some places where higher goods are only transported occasionally, a large forklift is configured to meet occasional needs, which leads to increased costs. Moreover, the large forklift also needs to create a working space when transporting lower goods, and for some small space areas, this method is obviously not very suitable. Utility Model Content
