What are the characteristics of an electric forklift?
Electric forklift is a type of wheeled vehicle that does not cause exhaust gas pollution, and is used for loading, unloading, stacking, and short distance transportation of finished pallet goods. The International Organization for Standardization ISO/TC110 is known as industrial vehicles, and electric forklifts are often used for storing large items during transportation.
What are the characteristics of an electric forklift?
Forklifts are divided into two categories based on their power devices: battery powered forklifts and internal combustion forklifts.
Battery powered forklifts often use direct current (DC) series motors, whose mechanical characteristics meet the working requirements of forklifts for low speed and high torque. With the development of AC technology and the improvement of controllers, the use of AC motors has increased. The maintenance of AC motors is more convenient than that of DC motors, but the disadvantage is that the cost is higher than that of DC motors. In addition, the other advantages of battery powered forklifts are simple operation, convenient maintenance, soft operation, no noise, and no exhaust emissions. The disadvantage is that it requires: a charging room and charging equipment, long charging time, and high road requirements. Due to the limitation of battery capacity, the electric motor has low power, low climbing ability, slower operating speed than internal combustion engine forklifts, high basic investment, and small weight.
The difference between electric forklifts and internal combustion forklifts is not only the power device, but also the walking motor and control device. However, the operating device, hydraulic system, rotating device, braking device, drive shaft, rotating bridge, etc. of forklifts are the same or similar to each other.
Electric forklift, like internal combustion engine forklift, is a common structural form of straight balanced forklift in battery forklift.
1. Power station: battery pack. The standard battery voltage is 24, 30, 48, 72V.
2. Lathe: It is the frame of a forklift, made of steel plates and welded together. Almost all components of a forklift are installed on the frame. When working, it is necessary to have sufficient strength and stiffness to withstand various load effects.
3. Transmission device: transmits the power of the electric motor to the driving wheels of the forklift.
4. Steering system: controls the direction of travel of the forklift.
5. Braking system: Delay the forklift’s movement and stop it.
6. Electric Motor and Electrical System 3360 The electrical system controls the electric motor through various components, controls the oil pump motor or hydraulic steering pump motor, to achieve the start, stop, direction change, and speed of the forklift.
7. Workshop: It is the direct working mechanism for forklift loading and unloading operations. The forks of the goods are unloaded, and the elevators are completed by the workshop operator.
8. Hydraulic system: By using a hydraulic device to lift the fork, tilt the gantry forward and backward, and drive the hydraulic transmission belt, the purpose of loading goods and hydraulic direction is achieved.
