Forklifts are industrial transport vehicles used in ports, railway stations, airports, freight yards, factory workshops, warehouses, circulation centers and distribution centers, etc. are widely used. They are used for loading, unloading and handling palletized goods in cabins, wagons and containers

The technical parameters of the forklift are used to indicate the structural characteristics and working performance of the forklift. The most important technical parameters are nominal lifting weight, center of gravity distance, maximum lifting height, portal inclination, maximum driving speed, minimum turning radius, minimum ground clearance, wheelbase, wheelbase, etc.

Loaders can be divided into: drive system, mechanical system, hydraulic system, control system. As an organic whole, the performance of the loader refers not only to the performance of the mechanical parts of the working equipment, but also to the performance of the hydraulic system and control system.

In road construction, especially in high-quality road construction, the front shovel machine is used for filling and excavating road works, aggregates and loading asphalt mixtures and cement concrete yards. In addition, he can also perform tasks such as pushing soil, scraping the soil and pulling other machines. Since the front shovel machine has the advantages of fast operating speed, high efficiency, good maneuverability and easy operation, it has become one of the main types of earthworks in civil engineering.
