Ottawa Scissor Lift Safety Training - A Scissor Lift is a helpful kind of platform that normally moves in a vertical direction. The machinery is capable of this movement because of the use of folding supports that are connected in a criss-cross pattern called 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. Some types of scissor lift even have an extending "bridge" which enables operators to have closer access to the work area because the vertical only movement could have some inherent restrictions.
There are numerous various types of scissor lifts on the market. They could be powered by various means like mechanical, via a lead screw or rack and pinion system, or pneumatic or hydraulic. Various kinds might need no power to enter "descent" mode but instead rely on a simple release of hydraulic or pneumatic pressure which depends on the power system utilized. These hydraulic and pneumatic methods of powering these lifts are preferred since releasing a manual valve provides a fail-safe option of returning the platform to the ground.
