A forklift (or fork crane) is a mechanical device used to move, lift and stack items. They are commonly used in industrial and storage locations to provide efficient logistics transportation and cargo management.

Here are some of the main functions of forklifts:

1. Handling items: Forklift trucks can handle heavy, large or inconvenient items. They insert a fork underneath the cargo and then lift it by lifting it and moving it to the desired position. Forklifts can be operated in narrow Spaces, making handling more convenient.

2. Lifting and stacking: Forklift trucks can lift items from the ground or low places to the required height through the lifting fork. This is useful for stacking goods in a warehouse to maximize the use of vertical space. Stacking forklifts also provide solid support and balance when stacking goods.

3. Loading and unloading of transport vehicles: Forklifts can be used to load and unload goods, such as unloading from trucks or containers, or loading goods onto transport vehicles. This saves manpower and time and improves the efficiency of loading and unloading operations.

4. Warehouse management: Forklift plays an important role in the warehouse. They can help move goods from the receiving area to the storage area, pick them up from the storage area on demand, and send them to the shipping area. By using forklifts, warehouse managers can organize and manage the flow of goods more efficiently.

5. Improve work efficiency: The use of forklifts can greatly improve the efficiency of handling and stacking operations. Compared with manual handling, forklifts can complete tasks more quickly and reduce the intensity and risk of manual labor.

It is important to note that the use of forklifts requires training and operational skills to ensure safety and effectiveness.
