Scissor Lifts
Scissor Lifts are just capable of lifting on a vertical plane and are particularly made for those projects directly overhead. Scissor Lifts are made with a series of crisscrossing linked supports. The pressure needs to 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 vertically propels the unit. If the equipment is hydraulically or pneumatically powered, lowering of the platform can be done by simply opening a valve in order to release the pressure.
There are a wide variety of scissor lift models that vary from indoor models to outdoor rough terrain models. The rough terrain scissor lift is made specifically for construction applications. The rough terrain models are particularly outfitted with more reliable and stronger tires which are powered by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are generally smaller models which depend on 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 kinds of lifts are utilized for maintenance tasks such as changing light bulbs and indoor tasks.
The first scissor lift was build during the 1970s. The fundamental design is still utilized, even if a lot of improvements have been made in the materials used and safety features added. This particular machinery became the best option for numerous indoor retail establishments that were beginning to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become sought after and 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.
