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 linked and folding supports that crisscross in an "x" pattern. The pressure should 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 to be able to release the pressure.
There are a large array of scissor lift types that vary from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed specially for construction applications. The rough terrain models are specifically equipped with more dependable and stronger tires which operate by gas or diesel motors.
4 Mechanical Lifts
Usually, mechanical lifts are smaller models which use screw threads or rack-and-pinion symptoms to raise the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they can lift. Mostly, these kinds of lifts are used for maintenance tasks such as changing light bulbs and indoor applications.
The very first scissor lift was made during the 1970s. The fundamental design is still used, even though many improvements have been made in the materials used and safety features added. This equipment became the best option for numerous indoor retail establishments which 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. In addition, the scissor lift offers the only industrial platforms that could be retracted and could fit into the corner of the building.
