Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead as they are only 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 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 that vertically propels the unit. If the machine 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 large array of scissor lift models that vary from indoor models to outdoor rough terrain models. The rough terrain scissor lift is designed specially for construction operations. The rough terrain types are specifically outfitted with stronger and more reliable tires that run by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are usually smaller models which rely upon rack-and-pinion or screw threads to elevate the platform. The mechanical lifts are limited in the heights they could extend to and the amount of weight they could lift. Mainly, these kinds of lifts are used for maintenance jobs like for example changing light bulbs and indoor applications.
The very first scissor lift was build in the 1970s. The basic design is still used, even if many improvements have been made in the materials used and safety features added. This equipment became the perfect choice for numerous indoor retail establishments that were starting to expand their inventory. The scissor lift is like the forklift. The scissor lift has become known and sought after for its effectiveness as well as its portability. Additionally, the scissor lift offers the only industrial platforms which could be retracted and could fit into the corner of the building.
