Scissor Lift Safety Training Kelowna - A Scissor Lift is a functional kind of platform which normally moves in a vertical direction. The equipment 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 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. Some types of scissor lift also have an extending "bridge" that enables operators to have closer access to the work area since the vertical only movement could have some inherent limits.
There are lots of various types of scissor lifts on the market. They can be powered by different means like for example mechanical, via a lead screw or rack and pinion system, or hydraulic or pneumatic. Several kinds might require no power to enter "descent" mode but instead depend on a simple release of pneumatic or hydraulic pressure that depends on the power system utilized. These pneumatic and hydraulic methods of powering these lifts are preferred as releasing a manual valve provides a fail-safe option of returning the platform to the ground.
