Scissor Lifts
Scissor Lifts are particularly made for working on projects directly overhead since 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 elevate into the air. This process extends the crossing pattern that vertically propels the unit. If the equipment is pneumatically or hydraulically powered, lowering of the platform could be done by easily opening a valve in order to release the pressure.
There are various scissor lift models. They can differ from indoor models to those models particularly designed for rough terrain that are better suitable for different construction applications. The rough terrain models are specifically equipped with more reliable and stronger tires which run by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are usually smaller models that rely upon screw threads or rack-and-pinion to raise the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they are able to carry. Mostly, these types of lifts are utilized for maintenance tasks like for example changing light bulbs and indoor tasks.
The very first scissor lift was build 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 best alternative for lots of indoor retail establishments which were beginning to expand their inventory. The scissor lift is a relative to the forklift. The scissor lift has become sought after and known for its portability as well as its effectiveness. In addition, the scissor lift offers the only industrial platforms that could be retracted and able to fit into the corner of the building.
