Scissor Lift Safety Training Penticton - 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 which are linked in what is known as a pantograph. The platform can 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 machinery to rise. Various types of scissor lift also have an extending "bridge" which enables operators to have closer access to the work area since the vertical only movement could have some inherent restrictions.
There are lots of different models of scissor lifts available. They could be powered by a variety of ways like for instance mechanical, via a lead screw or rack and pinion system, or pneumatic or hydraulic. Several types may need no power to enter "descent" mode but instead depend on a simple release of hydraulic or pneumatic pressure depending on the power system employed. 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.
