Description

Technical Field

[0001] The utility model relates to the field of forklift counterweights, in particular to a separate installation structure of a forklift counterweight. Background Art

[0002] The forklift counterweight is an important part of the forklift. Its main function is to increase the weight of the forklift, thereby improving the stability of the forklift. When the forklift is working, the fork arm rises or falls, which will generate a counter-gravity moment. If there is no support from the counterweight, the forklift will overturn. Therefore, the addition of a counterweight can greatly improve the safety and stability of the forklift.

[0003] The forklift counterweight is usually fixed to the forklift by bolts, and the nut types on the bolts on different forklifts are also different, which results in the need to use different types of wrenches, which is troublesome.

[0004] Therefore, we make improvements to this and propose a separate installation structure for a forklift counterweight. Utility Model Content
