Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead as they are only capable of lifting on a vertical plane. Scissor Lifts are made of a series of folding and linked supports which crisscross in an "x" pattern. The pressure needs to 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 that propels the unit vertically. If the machinery is pneumatically or hydraulically powered, lowering of the platform can be achieved by simply opening a valve to be able to release the pressure.
There are a variety of scissor lift models. They can differ from indoor models to those models particularly designed for rough terrain that are better suited for various construction operations. The rough terrain types are specially equipped with stronger and more dependable tires which are powered by diesel or gas engines.
4 Mechanical Lifts
Mechanical lifts are generally smaller models which rely on rack-and-pinion or screw threads to elevate the platform. The mechanical lifts are limited in the amount of weight they can lift and the heights they could extend to. Mainly, these lift types are used for maintenance jobs like indoor tasks and changing light bulbs.
In the 1970s, the first scissor lifts were built. Even if numerous improvements have been made since that time in the categories of materials and safety, the basic original design is still usually utilized. This particular machine became the ideal choice for a lot of 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 known for its effectiveness and its portability. Furthermore, the scissor lift offers the only industrial platforms that could be retracted and can fit into the corner of the building.
