Scissor Lifts
Scissor Lifts are specifically 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 must be applied to the outside of the lowest set of supports in order for the unit to rise up into the air. This process extends the crossing pattern that propels the unit vertically. If the machine is hydraulically or pneumatically powered, lowering of the platform can be achieved by simply opening a valve to be able to release the pressure.
There are various scissor lift types. They can vary from indoor models to those models specifically made for rough terrain that are better suited for various construction applications. The rough terrain types are particularly outfitted with stronger and more reliable tires which are powered by diesel or gas engines.
4 Mechanical Lifts
Normally, mechanical lifts are smaller models which utilize screw threads or rack-and-pinion symptoms to lift the platform. The mechanical lifts are limited in the amount of weight they can lift and the heights they can extend to. Mainly, these types of lifts are used for maintenance tasks like changing light bulbs and indoor applications.
During the 1970s, the very first scissor lifts were made. Even if several improvements have been made since that time in the categories of materials and safety, the basic original design is still normally used. This machine became the perfect choice for many indoor retail establishments that were starting 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. Furthermore, the scissor lift provides the only industrial platforms which could be retracted and can fit into the corner of the building.
