How does the hydraulic system of an electric forklift work?
The hydraulic system of an electric forklift mainly uses the pressure of hydraulic oil to achieve the lifting and moving of goods. Its working principle is as follows:

1. Hydraulic oil tank: The hydraulic system stores hydraulic oil and provides the required hydraulic medium.

2. Hydraulic pump: The electric motor of the electric forklift drives the hydraulic pump, which draws the hydraulic oil from the tank and pressurizes it.

3. Control valve: Through the operating handle, the control valve adjusts the flow direction and pressure of the hydraulic oil and determines which hydraulic cylinder the hydraulic oil flows to.

4. Hydraulic cylinder: The hydraulic oil enters the hydraulic cylinder and pushes the piston to move. The movement of the piston causes the forklift's forks to rise and fall.

5. Oil return system: When the goods are raised or lowered, the hydraulic oil flows back to the tank through the oil return pipe to prepare for the next operation.

The advantage of this system is that it can provide greater power and is simple to operate, making it suitable for use in environments such as warehouses and factories.
