[0002] Forklifts are industrial handling vehicles, which refer to various wheeled handling vehicles that load and unload, stack and transport palletized goods over short distances. The International Organization for Standardization ISO / TC110 calls them industrial vehicles. They are often used for transporting large objects in warehouses and are usually powered by fuel engines or batteries.

[0003] The forklift counterweight is a cast iron block installed at the rear of the electric forklift frame. It is used to increase the stability and center of gravity of the forklift. Its importance lies in ensuring that the forklift can remain safe and stable when transporting heavy objects.

[0004] Existing forklift counterweights with adjustable size adopt modular design, and the size and weight of the counterweight can be adjusted by combining different numbers and types of counterweight modules. However, although the total weight can be adjusted by increasing or decreasing the number of counterweight modules, the weight of such adjustment modules is usually fixed and cannot be fine-tuned as needed, and thus cannot accurately meet certain specific work requirements. Therefore, those skilled in the art provide a forklift counterweight with adjustable size to solve the problems raised in the above background technology. Utility Model Content
