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 should 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 propels the unit vertically. If the machine is pneumatically or hydraulically powered, lowering of the platform can be done by simply 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 models specially made for rough terrain that are better suited for different construction applications. The rough terrain types are particularly equipped with more reliable and stronger tires which operate by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are generally 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 could carry and the heights they could extend to. Mainly, these lift models are used for maintenance jobs such as changing light bulbs and indoor applications.
In the 1970s, the first scissor lifts were built. Even if various improvements have been made ever since that time in the categories of materials and safety, the essential original design is still often utilized. This equipment became the perfect choice for lots of indoor retail establishments which were beginning to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become sought after and well-known for its effectiveness as well as its portability. Additionally, the scissor lift provides the only industrial platforms that could be retracted and can fit into the corner of the building.
