[0002] A forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. The International Organization for Standardization ISO / TC110 calls it an industrial vehicle. It is often used for the transportation of large objects in warehouses and is usually driven by a fuel engine or battery. The technical parameters of a forklift are used to indicate the structural characteristics and working performance of the forklift. The main technical parameters include: rated lifting capacity, load center distance, maximum lifting height, mast inclination angle, maximum travel speed, minimum turning radius, minimum ground clearance, wheelbase, track width, etc.
