Scissor Lift Safety Training Victoria - A Scissor Lift is a functional type of platform that usually moves in a vertical direction. The apparatus is capable of this movement because of the use of folding supports that are linked in a criss-cross pattern known 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 machine to rise. Several models of scissor lift also 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.
There are lots of various models of scissor lifts on the market. They could be powered by various ways like mechanical, via a lead screw or rack and pinion system, or pneumatic or hydraulic. Some models may need no power to enter "descent" mode but instead rely 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 since releasing a manual valve gives a fail-safe option of returning the platform to the ground.
