Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead because they are only capable of lifting on a vertical plane. Scissor Lifts are made of a series of folding and linked supports that crisscross in an "x" pattern. The pressure should 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 that vertically propels the unit. If the equipment is pneumatically or hydraulically powered, lowering of the platform can be achieved by easily opening a valve to be able to release the pressure.
There are a wide array of scissor lift types which differ from outdoor rough terrain models to indoor models. The rough terrain scissor lift is made specially for construction applications. The rough terrain models are particularly outfitted with more dependable and stronger tires that are powered by gas or diesel motors.
4 Mechanical Lifts
Normally, mechanical lifts are smaller models that use screw threads or rack-and-pinion symptoms to raise the platform. The mechanical lifts are limited in the amount of weight they could lift and the heights they could extend to. Mainly, these types of lifts are utilized for maintenance tasks like indoor applications and changing light bulbs.
The first scissor lift was build in the 1970s. The fundamental design is still used, even though many improvements have been made in the materials utilized 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 a relative to the forklift. The scissor lift has become sought after and well-known for its effectiveness and its portability. Additionally, the scissor lift provides the only industrial platforms which could be retracted and can fit into the corner of the building.
