Scissor Lift Safety Training Ottawa - A Scissor Lift is a useful type of platform which generally 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 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 since the vertical only movement can have some inherent restrictions.
There are a lot of different kinds of scissor lifts on the market. They can be powered by different ways like for example mechanical, via a rack and pinion or lead screw system, or pneumatic or hydraulic. Some types might need 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 as releasing a manual valve provides a fail-safe choice of returning the platform to the ground.
