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 linked and folding supports that 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 elevate 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 can be done by easily opening a valve to be able to release the pressure.
There are a variety of scissor lift types. They could differ from indoor models to those models specially designed for rough terrain which are better suited for various construction applications. The rough terrain models are specifically outfitted with more dependable and stronger tires which are powered by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are normally smaller models that rely on rack-and-pinion or screw threads to raise the platform. The mechanical lifts are limited in the heights they could extend to and the amount of weight they can lift. Mainly, these lift models are used for maintenance jobs such as indoor tasks and changing light bulbs.
In the 1970s, the first scissor lifts were made. Even if various improvements have been made ever since that time in the categories of safety and materials, the basic original design is still usually utilized. This equipment became the best choice for many indoor retail establishments which 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. Furthermore, the scissor lift provides the only industrial platforms which could be retracted and can fit into the corner of the building.
