Scissor Lift Safety Training Whitby - A scissor lift is a type of platform lift which moves vertically. The lift table is moved in a vertical motion because of criss-cross folding supports that are linked in what is called a pantograph. The platform can 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 types of scissor lift likewise have an extending "bridge" that enables operators to have closer access to the work area as the vertical only movement can have some inherent restrictions.
There are a lot of different kinds of scissor lifts obtainable. They can be powered by different means including mechanical, via a lead screw or rack and pinion system, or pneumatic or hydraulic. Several kinds may require no power to enter "descent" mode but instead depend on a simple release of pneumatic or hydraulic pressure which depends on the power system employed. These pneumatic and hydraulic methods of powering these lifts are preferred as releasing a manual valve gives a fail-safe option of returning the platform to the ground.
