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 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 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 could be done by simply opening a valve to be able to release the pressure.
There are various scissor lift types. They can vary from indoor models to those models particularly made for rough terrain which are better suited for different construction operations. The rough terrain models are specifically outfitted with more dependable and stronger tires which run by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are normally smaller models that depend upon screw threads or rack-and-pinion to elevate the platform. The mechanical lifts are limited in the amount of weight they can lift and the heights they could extend to. Mostly, these kinds of lifts are utilized for maintenance tasks like indoor applications and changing light bulbs.
The very first scissor lift was build in the 1970s. The basic design is still utilized, even if a lot of improvements have been made in the materials used and safety features added. This particular equipment became the perfect alternative for numerous indoor retail establishments that were beginning 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. Moreover, the scissor lift offers the only industrial platforms that could be retracted and could fit into the corner of the building.
