Scissor lift lifting principle

Scissor lift lifting principle

The scissor lift achieves the lifting function through the hydraulic system. When the hydraulic pump is activated, 

hydraulic oil is pumped into the hydraulic cylinder, causing the piston of the hydraulic cylinder to move upward. 

The piston is connected to the scissor fork, and when the piston rises, the scissor fork also rises. 

On the contrary, when the hydraulic pump stops working, the piston of the hydraulic cylinder goes down, 

and the shear fork also goes down. 

By controlling the operational status of the hydraulic system, the lifting height and speed of the scissor lift 

can be precisely controlled.

The power source of the scissor lift

Scissor lifts usually use electricity as the power source. Hydraulic pumps and electric motors are 

the primary power sources of scissor lifts. 

The electric motor drives the hydraulic pump to generate energy and deliver oil to the 

hydraulic cylinder. 

The work of the hydraulic pump can be controlled by a switch or a button on the control panel to 

achieve the lifting function of the lift.

Workflow of scissor lift

The workflow of a scissor lift usually includes the following steps:

a. Preparation: Check the hydraulic oil level of the lift, power connection, etc., 

to ensure that the equipment is in normal working condition.

b. Adjust the height: According to the demand, adjust the lifting height of the lift through the control 

panel or switch to adapt it to the specific work scenario.

c. Load/unload: Place the goods on the lift platform and make sure the goods are stable and reliable.

d. Lifting operation: By operating the control system, start the hydraulic pump to raise the hydraulic 

cylinder and lift the cargo to the required height.

e. Fix the cargo: After reaching the target height, take the necessary safety measures to ensure

 the load is stable and fixed on the lift platform.

f. Complete the task: After transporting the cargo to the target position, stop the hydraulic pump from 

working through the control system to lower the hydraulic cylinder and unload the load safely.

g. Shutdown/Maintenance: After finishing the job, turn off the Power and perform routine maintenance

 to ensure the reliable long-term operation of the lift.
