Scissor Lifts
Scissor Lifts are particularly made for working on projects directly overhead since they are just capable of lifting on a vertical plane. Scissor Lifts are made of a series of linked and folding 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 elevate into the air. This process extends the crossing pattern that propels the unit vertically. If the equipment 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 wide array of scissor lift models that differ from outdoor rough terrain models to indoor models. The rough terrain scissor lift is made specifically for construction applications. The rough terrain models are specially equipped with stronger and more dependable tires which are powered by diesel or gas engines.
4 Mechanical Lifts
Mechanical lifts are usually smaller models that depend upon screw threads or rack-and-pinion to raise the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they could lift. Mainly, these lift models are utilized for maintenance tasks such as changing light bulbs and indoor applications.
The very first scissor lift was made during the 1970s. The fundamental design is still used, even though lots of improvements have been made in the materials used and safety features added. This particular machinery became the ideal option for many indoor retail establishments which were beginning 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. Furthermore, the scissor lift provides the only industrial platforms which could be retracted and can fit into the corner of the building.
