Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are particularly made for those projects directly overhead. Scissor Lifts are made with a series of crisscrossing linked supports. The pressure should be applied to the outside of the lowest set of supports in order for the unit to elevate into the air. This process elongates the crossing pattern that propels the unit vertically. If the machinery 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 a variety of scissor lift models. They can differ from indoor models to those types particularly made for rough terrain that are better suited for different construction applications. The rough terrain types are particularly outfitted with more reliable and stronger tires which are powered by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are normally smaller models which rely upon rack-and-pinion or screw threads to raise the platform. The mechanical lifts are limited in the amount of weight they could carry and the heights they can extend to. Mainly, these kinds of lifts are utilized for maintenance jobs like indoor tasks and changing light bulbs.
The first scissor lift was build during the 1970s. The fundamental design is still utilized, even though many improvements have been made in the materials used and safety features added. This particular equipment became the ideal alternative for many indoor retail establishments which were beginning to expand their inventory. The scissor lift is a relative to the forklift. The scissor lift has become known and sought after for its portability and its effectiveness. Moreover, the scissor lift provides the only industrial platforms that could be retracted and could fit into the corner of the building.
