Scissor Lifts
Scissor Lifts are specifically 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 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 elongates the crossing pattern which vertically propels the unit. If the equipment is pneumatically or hydraulically powered, lowering of the platform can be achieved by easily opening a valve to be able to release the pressure.
There are a large 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 applications. The rough terrain models are specifically equipped with more dependable and stronger tires which are powered by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are normally smaller models that rely on screw threads or rack-and-pinion to lift the platform. The mechanical lifts are limited in the amount of weight they are able to carry and the heights they could extend to. Mainly, these kinds of lifts are used for maintenance tasks like indoor applications and changing light bulbs.
During the 1970s, the first scissor lifts were made. Even though numerous improvements have been made since that time in the categories of materials and safety, the essential original design is still usually utilized. This machine became the best option for lots of indoor retail establishments which were starting 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. Moreover, the scissor lift provides the only industrial platforms which could be retracted and could fit into the corner of the building.
