Ontario Scissor Lift Safety Training - A Scissor Lift is a functional kind of platform that normally moves in a vertical direction. The apparatus is capable of this movement due to the use of folding supports which are connected in a criss-cross pattern referred to as a pantograph. The platform is able to propel vertically because of the application of pressure to the outside of the lowest set of supports. This elongates the crossing pattern and causes the machine to rise. Some kinds of scissor lift even have an extending "bridge" that enables operators to have closer access to the work area because the vertical only movement could have some inherent limits.
Scissor Lifts could contract by a variety of ways including mechanical, via a rack and pinion or lead screw system, or pneumatic or hydraulic. There are various models existing on the market. Various kinds may need no power to enter "descent" mode but instead rely on a simple release of hydraulic or pneumatic pressure that 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.
