Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead since they are only capable of lifting on a vertical plane. Scissor Lifts are designed of a series of folding and linked supports that crisscross in an "x" pattern. The pressure needs to 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 vertically propels the unit. If the equipment is hydraulically or pneumatically powered, lowering of the platform can be achieved by easily opening a valve in order to release the pressure.
There are a wide variety of scissor lift types which differ from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed specially for construction applications. The rough terrain types are particularly equipped with more reliable and stronger tires which operate by gas or diesel engines.
4 Mechanical Lifts
Normally, mechanical lifts are smaller models that use screw threads or rack-and-pinion symptoms to lift the platform. The mechanical lifts are limited in the heights they could extend to and the amount of weight they could lift. Mostly, these types of lifts are utilized for maintenance tasks such as changing light bulbs and indoor applications.
In the 1970s, the very first scissor lifts were made. Even though many improvements have been made ever since that time in the categories of safety and materials, the basic original design is still often used. This equipment became the best choice for numerous indoor retail establishments which were starting to expand their inventory. The scissor lift is a relative to the forklift. The scissor lift has become sought after and known for its effectiveness as well as its portability. In addition, the scissor lift offers the only industrial platforms that could be retracted and able to fit into the corner of the building.
