Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead since 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 must 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 which vertically propels the unit. If the machine is pneumatically or hydraulically powered, lowering of the platform can be done by simply opening a valve to be able to release the pressure.
There are a wide variety of scissor lift types which differ from indoor models to outdoor rough terrain models. The rough terrain scissor lift is made specifically for construction applications. The rough terrain models are specifically outfitted with more reliable and stronger tires which are powered by diesel or gas engines.
4 Mechanical Lifts
Mechanical lifts are usually smaller models that depend upon rack-and-pinion or screw threads to lift the platform. The mechanical lifts are limited in the amount of weight they can carry and the heights they can extend to. Mostly, these lift types are utilized for maintenance jobs like for example changing light bulbs and indoor applications.
The first scissor lift was made in the 1970s. The basic design is still used, even though many improvements have been made in the materials utilized and safety features added. This particular machinery became the perfect alternative for numerous indoor retail establishments which were beginning to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become known and sought after for its effectiveness as well as its portability. Moreover, the scissor lift provides the only industrial platforms that could be retracted and able to fit into the corner of the building.
