Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead as they are only capable of lifting on a vertical plane. Scissor Lifts are made of a series of folding and linked supports that crisscross in an "x" pattern. 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 that propels the unit vertically. If the machine is hydraulically or pneumatically powered, lowering of the platform can be achieved by easily opening a valve in order to release the pressure.
There are a variety of scissor lift types. They can vary from indoor models to those models specially designed for rough terrain which are better suitable for different construction operations. The rough terrain models are specially equipped with stronger and more reliable tires which operate by diesel or gas motors.
4 Mechanical Lifts
Generally, mechanical lifts are smaller models which use screw threads or rack-and-pinion symptoms to lift the platform. The mechanical lifts are limited in the heights they could extend to and the amount of weight they could lift. Mainly, these kinds of lifts are used for maintenance jobs like for instance indoor tasks and changing light bulbs.
In the 1970s, the first scissor lifts were built. Even if numerous improvements have been made ever since that time in the categories of materials and safety, the basic original design is still usually utilized. This equipment became the ideal alternative for many indoor retail establishments which were beginning 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 and its portability. Additionally, the scissor lift provides the only industrial platforms that could be retracted and able to fit into the corner of the building.
