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 folding and linked supports that 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 equipment is pneumatically or hydraulically powered, lowering of the platform could be achieved by easily opening a valve in order to release the pressure.
There are a large array of scissor lift models that differ from indoor models to outdoor rough terrain models. The rough terrain scissor lift is made particularly for construction operations. The rough terrain types are specifically outfitted with stronger and more dependable tires which operate by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are generally smaller models that rely on rack-and-pinion or screw threads to lift the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they are able to lift. Mostly, these types of lifts are utilized for maintenance jobs such as indoor tasks and changing light bulbs.
During the 1970s, the very first scissor lifts were built. Even though numerous improvements have been made since that time in the categories of materials and safety, the essential original design is still normally used. This particular equipment became the best option for numerous indoor retail establishments that were beginning to expand their inventory. The scissor lift is like the forklift. The scissor lift has become well-known and sought after for its effectiveness as well as its portability. In addition, the scissor lift provides the only industrial platforms that could be retracted and can fit into the corner of the building.
