Nanaimo Scissor Lift Safety Training - A Scissor Lift is a functional kind of platform which usually moves in a vertical direction. The machinery is capable of this movement due to the use of folding supports which are connected 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 machinery to rise. Various types of scissor lift also have an extending "bridge" which enables operators to have closer access to the work area because the vertical only movement could have some inherent limits.
Scissor Lifts can contract by several means like for example mechanical, via a rack and pinion or lead screw system, or hydraulic or pneumatic. There are a wide variety of types available on the market. Some types might 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 hydraulic and pneumatic methods of powering these lifts are preferred since releasing a manual valve gives a fail-safe alternative of returning the platform to the ground.
