Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are specifically made for those projects directly overhead. Scissor Lifts are made with a series of crisscrossing linked supports. 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 that propels the unit vertically. If the machine is pneumatically or hydraulically powered, lowering of the platform could be done by simply 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 suited for various construction applications. The rough terrain types are particularly equipped with more dependable and stronger tires that are powered by diesel or gas engines.
4 Mechanical Lifts
Mechanical lifts are usually smaller models that rely on rack-and-pinion or screw threads to raise the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they are able to lift. Mainly, these kinds of lifts are used for maintenance tasks like changing light bulbs and indoor applications.
In the 1970s, the very first scissor lifts were built. Even though various improvements have been made ever since that time in the categories of safety and materials, the basic original design is still often used. This particular machinery became the best choice for many indoor retail establishments which were starting to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become known and sought after for its portability as well as its effectiveness. In addition, the scissor lift provides the only industrial platforms that could be retracted and able to fit into the corner of the building.
