Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead as they are just capable of lifting on a vertical plane. Scissor Lifts are designed of a series of linked and folding supports that 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 rise up 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 various scissor lift models. They could differ from indoor models to those models specifically made for rough terrain which are better suitable for various construction applications. The rough terrain models are particularly outfitted with stronger and more reliable tires which run by diesel or gas engines.
4 Mechanical Lifts
Mechanical lifts are usually smaller models that rely upon rack-and-pinion or screw threads to lift the platform. The mechanical lifts are limited in the amount of weight they could carry and the heights they can extend to. Mostly, these lift models are used for maintenance tasks like for instance changing light bulbs and indoor applications.
The first scissor lift was build in the 1970s. The basic design is still utilized, even if many improvements have been made in the materials utilized and safety features added. This particular machine became the best choice for many indoor retail establishments which 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 effectiveness as well as its portability. Additionally, the scissor lift offers the only industrial platforms which could be retracted and could fit into the corner of the building.
