Scissor Lifts
Scissor Lifts are particularly made for working on projects directly overhead since they are just 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 must 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 machinery is hydraulically or pneumatically powered, lowering of the platform can be done by easily opening a valve to be able to release the pressure.
There are a wide variety of scissor lift models that vary from indoor models to outdoor rough terrain models. The rough terrain scissor lift is made particularly for construction operations. The rough terrain models are specifically equipped with stronger and more reliable tires that run by gas or diesel motors.
4 Mechanical Lifts
Mechanical lifts are generally smaller models which depend on 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 used for maintenance jobs like changing light bulbs and indoor applications.
During the 1970s, the very first scissor lifts were made. Even though numerous improvements have been made ever since that time in the categories of safety and materials, the basic original design is still usually used. This particular equipment became the ideal 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 sought after and known for its effectiveness as well as its portability. Moreover, the scissor lift offers the only industrial platforms which could be retracted and can fit into the corner of the building.
