Scissor Lifts
Scissor Lifts are particularly made for working on projects directly overhead as they are just capable of lifting on a vertical plane. Scissor Lifts are designed of a series of linked and folding supports that 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 elevate into the air. This process elongates the crossing pattern which vertically propels the unit. If the machinery 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 types which differ from outdoor rough terrain models to indoor models. The rough terrain scissor lift is made specially for construction operations. The rough terrain models are specifically outfitted with stronger and more dependable tires which run by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are usually smaller models that depend upon screw threads or rack-and-pinion to elevate 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 lift types are used for maintenance tasks such as changing light bulbs and indoor applications.
The first scissor lift was build during the 1970s. The fundamental design is still utilized, even if lots of improvements have been made in the materials utilized and safety features added. This equipment became the perfect option for numerous indoor retail establishments that 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 as well as its effectiveness. Moreover, the scissor lift provides the only industrial platforms which could be retracted and could fit into the corner of the building.
