Forklifts can generally be divided into three categories: internal combustion forklifts, electric forklifts and storage forklifts.

Internal combustion forklifts are divided into ordinary internal combustion forklifts, heavy forklifts, container forklifts and side forklifts.
① Ordinary internal combustion forklift
Generally, diesel, gasoline, liquefied petroleum gas or natural gas engines are used as power, with a load capacity of 1.2 to 8.0 tons, and the width of the working channel is generally 3.5 to 5.0 meters. Considering the exhaust emission and noise issues, it is usually used outdoors, in workshops or other places that deal with exhaust gas. There are no special requirements for emissions and noise. Due to the convenience of fuel replenishment, it can realize continuous operation for a long time, and is also capable of working in harsh environments (such as rainy days).
②Heavy-duty forklift
Diesel engine is used as the power, and the carrying capacity is 10.0-52.0 tons. It is generally used for outdoor operations in heavy cargo wharfs, steel and other industries.
③ Container forklift
Diesel engines are used as power, and the carrying capacity is 8.0-45.0 tons. It is generally divided into empty container stacker, heavy container stacker and container reach stacker. Used in container handling, such as container yards or port terminal operations.
④ Side forklift
It uses a diesel engine as power and has a carrying capacity of 3.0 to 6.0 tons. It has the ability to fork goods directly from the side without turning, so it is mainly used to fork long goods, such as wooden strips, steel bars, etc.

Electric
The electric motor is used as the power, and the battery is used as the energy source. The carrying capacity is 1.0 to 8.0 tons, and the working channel width is generally 3.5 to 5.0 meters. Because there is no pollution and low noise, it is widely used in indoor operations and other working conditions with high environmental requirements, such as medicine, food and other industries. As people pay more attention to environmental protection, electric forklifts are gradually replacing internal combustion forklifts. Since each set of batteries generally needs to be charged after working for about 8 hours, a backup battery is required for multi-shift working conditions.

Storage
Warehousing forklifts are mainly forklifts designed for handling goods in warehouses. Except for a few warehousing forklifts (such as manual pallet forklifts) which are driven by manpower, others are driven by electric motors. They are widely used in the warehousing industry because of their compact body, flexible movement, light weight and good environmental performance. When operating in multiple shifts, motor-driven warehouse forklifts require backup batteries.
