Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are particularly made for those projects directly overhead. Scissor Lifts are designed 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 rise up into the air. This process elongates the crossing pattern which propels the unit vertically. If the machine is hydraulically or pneumatically powered, lowering of the platform can be achieved by simply opening a valve to be able to release the pressure.
There are various scissor lift models. They could differ from indoor models to those types specially made for rough terrain which are better suited for different construction operations. The rough terrain types are specially equipped with more dependable and stronger tires which operate by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are normally smaller models that depend upon rack-and-pinion or screw threads to raise the platform. The mechanical lifts are limited in the amount of weight they are able to carry and the heights they can extend to. Mostly, these lift types are utilized for maintenance jobs like indoor applications and changing light bulbs.
The first scissor lift was build in the 1970s. The fundamental design is still utilized, even though a lot of improvements have been made in the materials used and safety features added. This particular machinery became the perfect 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 sought after and known for its effectiveness as well as its portability. In addition, the scissor lift provides the only industrial platforms which could be retracted and able to fit into the corner of the building.
