Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are specifically made for those projects directly overhead. Scissor Lifts are designed with a series of crisscrossing linked supports. The pressure should 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 which vertically propels the unit. If the machinery 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 variety of scissor lift types. They can vary from indoor models to those models specifically designed for rough terrain which are better suitable for different construction applications. The rough terrain models are specially outfitted with more reliable and stronger tires which operate by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are normally smaller models which depend upon rack-and-pinion or screw threads to raise the platform. The mechanical lifts are limited in the amount of weight they can lift and the heights they could extend to. Mainly, these lift models are utilized for maintenance jobs such as indoor applications and changing light bulbs.
The first scissor lift was made during the 1970s. The basic design is still utilized, even though lots of improvements have been made in the materials utilized and safety features added. This particular equipment became the perfect choice for many indoor retail establishments which were beginning to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become sought after and well-known for its portability and its effectiveness. In addition, the scissor lift offers the only industrial platforms which could be retracted and can fit into the corner of the building.
