Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead because they are only 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 needs to be applied to the outside of the lowest set of supports in order for the unit to rise up 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 could be done by easily opening a valve to be able to release the pressure.
There are various scissor lift types. They could differ from indoor models to those models specifically designed for rough terrain that are better suitable for different construction applications. The rough terrain types are particularly equipped with stronger and more dependable tires that are powered by gas or diesel motors.
4 Mechanical Lifts
Mechanical lifts are generally smaller models which rely upon screw threads or rack-and-pinion to lift the platform. The mechanical lifts are limited in the amount of weight they could lift and the heights they can extend to. Mostly, these lift types are used for maintenance jobs such as changing light bulbs and indoor tasks.
During the 1970s, the first scissor lifts were built. Even though many improvements have been made since that time in the categories of materials and safety, the basic original design is still normally used. This particular machine became the perfect alternative for a lot of indoor retail establishments that 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 as well as its portability. Additionally, the scissor lift provides the only industrial platforms that could be retracted and could fit into the corner of the building.
