Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead because they are only capable of lifting on a vertical plane. Scissor Lifts are made of a series of folding and linked 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 rise up into the air. This process elongates the crossing pattern which vertically propels the unit. If the equipment is pneumatically or hydraulically powered, lowering of the platform could be achieved by simply opening a valve to be able to release the pressure.
There are various scissor lift models. They could vary from indoor models to those models specially made for rough terrain that are better suitable for various construction operations. The rough terrain models are particularly equipped with more reliable and stronger tires that operate by gas or diesel engines.
4 Mechanical Lifts
Usually, mechanical lifts are smaller models which utilize screw threads or rack-and-pinion symptoms to elevate the platform. The mechanical lifts are limited in the amount of weight they can lift and the heights they could extend to. Mainly, these kinds of lifts are utilized for maintenance tasks like changing light bulbs and indoor tasks.
The first scissor lift was made during the 1970s. The basic design is still used, even though many improvements have been made in the materials utilized and safety features added. This particular machinery became the perfect choice for lots of indoor retail establishments that were starting to expand their inventory. The scissor lift is like the forklift. The scissor lift has become known and sought after for its portability and its effectiveness. Moreover, the scissor lift offers the only industrial platforms that could be retracted and could fit into the corner of the building.
