Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are particularly made for those projects directly overhead. Scissor Lifts are designed with a series of crisscrossing linked supports. 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 elongates the crossing pattern which propels the unit vertically. If the machine is hydraulically or pneumatically powered, lowering of the platform could be done by simply opening a valve in order to release the pressure.
There are a variety of scissor lift types. They can vary from indoor models to those models specifically made for rough terrain that are better suitable for various construction operations. The rough terrain models are specially equipped with stronger and more dependable tires which operate by diesel or gas engines.
4 Mechanical Lifts
Mechanical lifts are usually smaller models which rely upon screw threads or rack-and-pinion to lift the platform. The mechanical lifts are limited in the heights they could extend to and the amount of weight they can carry. Mainly, these lift models are used for maintenance jobs such as changing light bulbs and indoor tasks.
In the 1970s, the very first scissor lifts were made. Even if numerous improvements have been made ever since that time in the categories of safety and materials, the essential original design is still often utilized. This machine became the perfect alternative for numerous 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 well-known for its portability as well as its effectiveness. In addition, the scissor lift provides the only industrial platforms which could be retracted and could fit into the corner of the building.
