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 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 hydraulically or pneumatically 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 types. They could vary from indoor models to those types particularly made for rough terrain which are better suitable for various construction operations. The rough terrain types are specifically equipped with stronger and more reliable tires which are powered by gas or diesel motors.
4 Mechanical Lifts
Mechanical lifts are normally smaller models which depend on screw threads or rack-and-pinion to lift the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they could carry. Mainly, these lift types are utilized for maintenance jobs such as changing light bulbs and indoor tasks.
The first scissor lift was made in the 1970s. The fundamental design is still used, even though many improvements have been made in the materials used and safety features added. This particular equipment became the ideal choice for many indoor retail establishments which were beginning 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. Moreover, the scissor lift offers the only industrial platforms which could be retracted and able to fit into the corner of the building.
