Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead because they are only capable of lifting on a vertical plane. Scissor Lifts are designed of a series of folding and linked supports which crisscross in an "x" pattern. The pressure should be applied to the outside of the lowest set of supports in order for the unit to rise up into the air. This process elongates the crossing pattern which vertically propels the unit. If the machine is hydraulically or pneumatically powered, lowering of the platform could be done by easily opening a valve to be able to release the pressure.
There are a large variety of scissor lift types which vary from indoor models to outdoor rough terrain models. The rough terrain scissor lift is designed particularly for construction applications. The rough terrain types are particularly equipped with stronger and more dependable tires which are powered by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are normally smaller models which depend upon screw threads or rack-and-pinion to lift the platform. The mechanical lifts are limited in the amount of weight they are able to lift and the heights they could extend to. Mostly, these lift types are used for maintenance jobs like for instance indoor applications and changing light bulbs.
The very first scissor lift was build during the 1970s. The fundamental design is still used, even if a lot of improvements have been made in the materials utilized and safety features added. This machine became the best choice for many indoor retail establishments that were starting to expand their inventory. The scissor lift is a relative to the forklift. The scissor lift has become sought after and well-known for its portability as well as its effectiveness. Furthermore, the scissor lift offers the only industrial platforms which could be retracted and can fit into the corner of the building.
