Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead since they are just capable of lifting on a vertical plane. Scissor Lifts are designed of a series of folding and linked 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 propels the unit vertically. If the machinery is pneumatically or hydraulically powered, lowering of the platform can be achieved by simply 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 particularly for construction operations. The rough terrain models are specifically outfitted with stronger and more reliable tires which run by gas or diesel motors.
4 Mechanical Lifts
Generally, mechanical lifts are smaller models which utilize screw threads or rack-and-pinion symptoms to elevate the platform. The mechanical lifts are limited in the amount of weight they are able to lift and the heights they could extend to. Mostly, these kinds of lifts are utilized for maintenance jobs such as indoor tasks and changing light bulbs.
In the 1970s, the first scissor lifts were built. Even if various improvements have been made ever since that time in the categories of safety and materials, the essential original design is still normally used. This equipment became the ideal choice for numerous indoor retail establishments that were beginning to expand their inventory. The scissor lift is like the forklift. The scissor lift has become sought after and known for its effectiveness and its portability. Furthermore, the scissor lift offers the only industrial platforms that could be retracted and able to fit into the corner of the building.
