Forklift design specifications

1 Scope

GB/T 43756-2024 is the Chinese design specification for forklift trucks, an unusually complete document of some sixty-five thousand words that establishes the general, structural, mechanical, electrical, hydraulic and safety design principles for the machine and specifies the design and calculation requirements and methods that go with them. A forklift is a vehicle deliberately designed to be unstable in a controlled way, a counterweight balancing a load held out in front of the front axle, and almost every requirement in the document follows from that: the stability calculation, the mast and the carriage, the frame and the counterweight, the axles, steering and brakes, the hydraulic circuit and its protection, the electrical system and the battery, the operator protection and the visibility. It applies to counterbalance lift trucks, reach trucks, side-loading trucks, straddle trucks, pallet-stacking trucks and lateral and front-stacking trucks as defined in GB/T 6104.1, and serves as a reference for other types. It takes effect on 1 October 2024.

This document establishes the overall, structural, mechanical, electrical, hydraulic and safety design principles for forklifts, and specifies the design and calculation requirements and methods. This document applies to counterbalanced forklifts, reach forklifts, side forklifts, leg forklifts, pallet forklifts, etc. Stacker and three-way stacker forklift. Other types of forklifts are used for reference.
