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 designed of a series of linked and folding supports that crisscross in an "x" pattern. The pressure should 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 which propels the unit vertically. If the machine is hydraulically or pneumatically powered, lowering of the platform can be done by easily opening a valve in order to release the pressure.
There are a variety of scissor lift types. They can differ from indoor models to those types particularly designed for rough terrain which are better suitable for various construction applications. The rough terrain types are specially outfitted with stronger and more reliable tires which are powered by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are generally smaller models that depend upon screw threads or rack-and-pinion to raise 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 jobs like for instance changing light bulbs and indoor applications.
During the 1970s, the first scissor lifts were built. Even if many improvements have been made since that time in the categories of safety and materials, the basic original design is still normally utilized. This particular equipment became the perfect choice for a lot of indoor retail establishments which were starting to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become well-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.
