Working principles of scissor lift platform

The working principle of the scissor lift platform is based on the scissor fork mechanism, which is a superposition of a planar linkage mechanism. The telescopic movement is achieved by changing the angle between the links, thereby lifting or lowering the platform to the desired position. The specific analysis is as follows:

Starting operation:

When the scissor lift platform is started, the motor starts to run. The controller controls the start and stop and running direction of the motor according to the instructions.

Transmission process:

The motor drives the movement of the scissor fork mechanism through the transmission device (usually a hydraulic cylinder or an electric cylinder). The transmission device converts the rotational movement of the motor into the extension or contraction movement of the scissor fork mechanism through the connecting rod.

Extension action:

During the extension process, the motor drives the transmission device to rotate, so that the scissor fork mechanism extends, the height of the lifting platform gradually increases, and the object is lifted to the desired height.

Contraction action:

During the contraction process, the motor rotates in the opposite direction, and the transmission device converts the movement into the contraction movement of the scissor fork mechanism. The height of the lifting platform gradually decreases, and the object is lowered to the desired position.

Structural advantages:

The design of the scissor lift mechanism allows a larger lifting range to be achieved through a smaller hydraulic cylinder or electric cylinder stroke. This four-bar linkage is small in size when contracted, which is easy to install and maintain.

Load capacity:

The scissor lift platform can withstand large loads and can safely lift heavy objects to a certain height, suitable for various heavy-duty operations.

Smooth lifting:

The structural design of the scissor fork mechanism ensures a smooth and vibration-free lifting process and ensures the safe transportation of objects.

Design reference:

The design of the scissor lift mechanism can refer to mature sizes and structures to optimize performance and reliability.

In general, the working principle of the scissor lift platform involves the starting of the motor, the conversion of the transmission device, the telescopic movement of the scissor fork mechanism, and the coordinated control of the entire system. These mechanisms work together to enable the lifting platform to complete the vertical transportation task of heavy objects while ensuring safety and efficiency.
