Scissor Lifts
Scissor Lifts are particularly made for working on projects directly overhead since they are just capable of lifting on a vertical plane. Scissor Lifts are designed of a series of linked and folding supports which crisscross in an "x" pattern. The pressure must be applied to the outside of the lowest set of supports in order for the unit to rise up into the air. This process extends the crossing pattern which vertically propels the unit. If the equipment is pneumatically or hydraulically powered, lowering of the platform could be done by easily opening a valve to be able to release the pressure.
There are a variety of scissor lift types. They can vary from indoor models to those models specially made for rough terrain that are better suited for different construction applications. The rough terrain models are specifically equipped with stronger and more reliable tires which are powered by gas or diesel motors.
4 Mechanical Lifts
Mechanical lifts are usually smaller models which rely upon screw threads or rack-and-pinion to raise the platform. The mechanical lifts are limited in the heights they could extend to and the amount of weight they can lift. Mostly, these lift types are utilized for maintenance jobs like for instance indoor applications and changing light bulbs.
The very first scissor lift was made 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 equipment became the best alternative for numerous indoor retail establishments that were starting to expand their inventory. The scissor lift is like the forklift. The scissor lift has become sought after and known for its portability as well as its effectiveness. Moreover, the scissor lift offers the only industrial platforms which could be retracted and able to fit into the corner of the building.
