Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead because they are only capable of lifting on a vertical plane. Scissor Lifts are designed 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 elevate into the air. This process elongates the crossing pattern that propels the unit vertically. If the equipment is pneumatically or hydraulically powered, lowering of the platform could be achieved by easily opening a valve in order to release the pressure.
There are a variety of scissor lift models. They could vary from indoor models to those models specifically made for rough terrain which are better suited for different construction operations. The rough terrain models are specially equipped with stronger and more reliable tires which are powered by diesel or gas engines.
4 Mechanical Lifts
Usually, mechanical lifts are smaller models which utilize screw threads or rack-and-pinion symptoms to raise the platform. The mechanical lifts are limited in the amount of weight they could lift and the heights they can extend to. Mainly, these types of lifts are used for maintenance jobs like indoor tasks and changing light bulbs.
The very first scissor lift was build in the 1970s. The fundamental design is still utilized, even though a lot of improvements have been made in the materials used and safety features added. This machinery became the ideal alternative for many indoor retail establishments that were starting to expand their inventory. The scissor lift is a relative to the forklift. The scissor lift has become sought after and well-known for its portability as well as its effectiveness. Moreover, the scissor lift provides the only industrial platforms that could be retracted and able to fit into the corner of the building.
