Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead since they are just 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 which propels the unit vertically. If the machine 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 large variety of scissor lift models which differ from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed particularly for construction applications. The rough terrain models are specially outfitted with stronger and more dependable tires which are powered by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are usually smaller models that depend on screw threads or rack-and-pinion to lift the platform. The mechanical lifts are limited in the amount of weight they could lift and the heights they could extend to. Mostly, these lift models are utilized for maintenance tasks like for instance indoor applications and changing light bulbs.
The very first scissor lift was build during the 1970s. The fundamental design is still used, even though a lot of improvements have been made in the materials utilized and safety features added. This particular machine became the best option for numerous indoor retail establishments that were starting to expand their inventory. The scissor lift is a relative to the forklift. The scissor lift has become known and sought after for its portability as well as its effectiveness. Furthermore, the scissor lift provides the only industrial platforms which could be retracted and able to fit into the corner of the building.
