A scissor lift is a work platform that is designed in a criss-cross fashion, hence the name. Scissor lifts are electric, hydraulic, or pneumatic. Such lifts can move only vertically to allow access to areas at a height and are used extensively in the manufacturing and construction industry.

Scissor lift mechanism

A scissor lift is a very common aerial lift nowadays because of its many advantages. It minimizes risk, is easy to operate, and can carry heavy loads. It is available in many different sizes and requires minimal storage space. It employs a very simple mechanism that we are going to look into below. Scissor lifts use simple parts to provide an efficient and quick work platform at height.

Platform

This is the space on which personnel and/or merchandise are positioned.

Base

This is the foundation on which the machinery rests.

Scissor Legs

These are the parts that allow the lift to ascend and descend.

Hydraulic cylinder

This is what lets the scissor legs move. One to three cylinders are positioned between the scissor legs.

Motor

This gives the machinery all the energy it needs to get raised or lowered.

To raise the platform, fluid is pushed into the cylinder. A control valve manages the level of fluid to help the platform maintain its height. When the fluid is released from the cylinder, the platform is lowered. To allow for a safe descent, fluid is released carefully, and its speed is managed by a control valve.
