Scissor Lift Safety Training Ontario - A scissor lift is a type of platform lift that moves vertically. The lift table is moved in a vertical motion because of criss-cross folding supports which are linked in what is referred to as a pantograph. The platform could 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 equipment to rise. Some kinds of scissor lift even have an extending "bridge" which enables operators to have closer access to the work area as the vertical only movement can have some inherent restrictions.
Scissor Lifts could contract by several means like for instance mechanical, via a rack and pinion or lead screw system, or pneumatic or hydraulic. There are a wide variety of kinds presented on the market. Some models 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 utilized. These pneumatic and hydraulic methods of powering these lifts are preferred as releasing a manual valve provides a fail-safe alternative of returning the platform to the ground.
