Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead as they are just capable of lifting on a vertical plane. Scissor Lifts are designed of a series of linked and folding supports which 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 elevate into the air. This process extends the crossing pattern which propels the unit vertically. If the machinery is pneumatically or hydraulically powered, lowering of the platform could be done by easily opening a valve to be able to release the pressure.
There are various scissor lift types. They could differ from indoor models to those models specially designed for rough terrain which are better suitable for different construction applications. The rough terrain types are specially outfitted with stronger and more dependable tires which operate by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are generally smaller models which depend on rack-and-pinion or screw threads to raise the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they can carry. Mainly, these lift models are used for maintenance jobs like for example indoor applications and changing light bulbs.
The first scissor lift was made during the 1970s. The basic design is still utilized, even though a lot of improvements have been made in the materials utilized and safety features added. This equipment became the ideal alternative for lots of indoor retail establishments which were starting to expand their inventory. The scissor lift is a relative to the forklift. The scissor lift has become well-known and sought after for its portability as well as its effectiveness. In addition, the scissor lift offers the only industrial platforms which could be retracted and could fit into the corner of the building.
