Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are specially made for those projects directly overhead. Scissor Lifts are made with a series of crisscrossing linked supports. The pressure must be applied to the outside of the lowest set of supports in order for the unit to elevate into the air. This process elongates the crossing pattern which vertically propels the unit. If the machinery is pneumatically or hydraulically powered, lowering of the platform could be done by easily opening a valve in order to release the pressure.
There are a variety of scissor lift models. They can differ from indoor models to those types specially made for rough terrain which are better suited for different construction applications. The rough terrain types are specifically equipped with more reliable and stronger tires that operate by diesel or gas motors.
4 Mechanical Lifts
Usually, mechanical lifts are smaller models which utilize screw threads or rack-and-pinion symptoms to lift the platform. The mechanical lifts are limited in the amount of weight they are able to carry and the heights they can extend to. Mainly, these kinds of lifts are used 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 used, even though a lot of improvements have been made in the materials used and safety features added. This machine became the ideal choice for lots of indoor retail establishments which were starting to expand their inventory. The scissor lift is like the forklift. The scissor lift has become sought after and well-known for its effectiveness as well as its portability. Furthermore, the scissor lift provides the only industrial platforms that could be retracted and can fit into the corner of the building.
