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 made of a series of folding and linked 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 elevate into the air. This process extends the crossing pattern that vertically propels the unit. If the equipment is hydraulically or pneumatically powered, lowering of the platform could be achieved by simply opening a valve to be able to release the pressure.
There are a wide array of scissor lift models which differ from indoor models to outdoor rough terrain models. The rough terrain scissor lift is made specially for construction applications. The rough terrain types are specifically equipped with more reliable and stronger tires that are powered by gas or diesel engines.
4 Mechanical Lifts
Generally, mechanical lifts are smaller models which use rack-and-pinion or screw threads symptoms to raise the platform. The mechanical lifts are limited in the amount of weight they are able to carry and the heights they could extend to. Mainly, these lift models are used for maintenance tasks 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 though a lot of improvements have been made in the materials utilized and safety features added. This machinery became the ideal alternative for numerous indoor retail establishments that were starting to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become known and sought after for its portability as well as its effectiveness. Additionally, the scissor lift provides the only industrial platforms which could be retracted and could fit into the corner of the building.
