Scissor Lift Safety Training Regina - A Scissor Lift is a functional kind of platform that normally moves in a vertical direction. The machinery is capable of this movement due to the use of folding supports that are linked in a criss-cross pattern called a pantograph. The platform is able to propel vertically due to the application of pressure to the outside of the lowest set of supports. This elongates the crossing pattern and causes the machine to rise. Various models of scissor lift even have an extending "bridge" which enables operators to have closer access to the work area since the vertical only movement could have some inherent limits.
Scissor Lifts could contract by several ways including mechanical, via a lead screw or rack and pinion system, or hydraulic or pneumatic. There are various types presented on the market. Several types may require no power to enter "descent" mode but instead rely on a simple release of pneumatic or hydraulic pressure which depends on the power system used. These hydraulic and pneumatic methods of powering these lifts are preferred as releasing a manual valve provides a fail-safe choice of returning the platform to the ground.
