Background technique

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 is called an industrial vehicle. It is often used for the transportation of large objects in storage, and is usually driven by a fuel engine or battery. The technical parameters of the forklift are used to indicate the structural characteristics and working performance of the forklift. The main technical parameters are: rated lifting capacity, load center distance, maximum lifting height, gantry inclination, maximum driving speed, minimum turning radius, minimum ground clearance, wheelbase, wheelbase, etc. When a traditional hoisting forklift is working, Due to the limited length of the fork, when carrying longer or wider goods, it is often necessary to manually put a longer fork on the basis of the original fork, and it must be unloaded again after the handling is completed. Make whole handling operation become very troublesome, also can't hoisting, wasted a large amount of manual labor.

Hoisting refers to the general term for the installation and positioning of equipment by a crane or a lifting mechanism. Hoisting is a special term for the placement of equipment.
