Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead because they are just capable of lifting on a vertical plane. Scissor Lifts are designed of a series of folding and linked supports that crisscross in an "x" pattern. The pressure must be applied to the outside of the lowest set of supports in order for the unit to rise up into the air. This process extends the crossing pattern that vertically propels the unit. If the machinery is pneumatically or hydraulically powered, lowering of the platform can be done by simply opening a valve in order to release the pressure.
There are a large array of scissor lift models that vary from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed specifically for construction operations. The rough terrain types are specially equipped with more dependable and stronger tires that run by diesel or gas engines.
4 Mechanical Lifts
Generally, mechanical lifts are smaller models that utilize rack-and-pinion or screw threads symptoms to raise the platform. The mechanical lifts are limited in the amount of weight they are able to carry and the heights they can extend to. Mostly, these lift types are used for maintenance tasks like changing light bulbs and indoor applications.
The very first scissor lift was made in the 1970s. The basic 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 option for numerous indoor retail establishments that were starting to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become known and sought after for its effectiveness as well as its portability. In addition, the scissor lift offers the only industrial platforms that could be retracted and able to fit into the corner of the building.
