Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead since they are just capable of lifting on a vertical plane. Scissor Lifts are made of a series of linked and folding supports which crisscross in an "x" pattern. The pressure has 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 that vertically propels the unit. If the machinery is hydraulically or pneumatically powered, lowering of the platform can be done by easily opening a valve to be able to release the pressure.
There are a wide variety of scissor lift models that differ from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed specifically for construction operations. The rough terrain types are particularly outfitted with more reliable and stronger tires which run by gas or diesel motors.
4 Mechanical Lifts
Normally, mechanical lifts are smaller models which utilize rack-and-pinion or screw threads symptoms to lift the platform. The mechanical lifts are limited in the amount of weight they can lift and the heights they could extend to. Mainly, these kinds of lifts are utilized for maintenance jobs such as indoor applications and changing light bulbs.
During the 1970s, the first scissor lifts were made. Even though various improvements have been made since that time in the categories of safety and materials, the basic original design is still normally utilized. This particular equipment became the ideal option for many indoor retail establishments that were starting to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become sought after and well-known for its effectiveness as well as its portability. Furthermore, the scissor lift offers the only industrial platforms which could be retracted and could fit into the corner of the building.
