Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are specifically made for those projects directly overhead. Scissor Lifts are made with a series of crisscrossing linked supports. 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 which propels the unit vertically. If the equipment is hydraulically or pneumatically powered, lowering of the platform can be achieved by simply opening a valve to be able to release the pressure.
There are a wide variety of scissor lift types which differ from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed specifically for construction applications. The rough terrain models are particularly equipped with more reliable and stronger tires that run by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are usually smaller models that depend on rack-and-pinion or screw threads to raise the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they are able to carry. Mostly, these lift types are used for maintenance tasks like for example changing light bulbs and indoor applications.
The very first scissor lift was made in the 1970s. The fundamental design is still utilized, even though a lot of improvements have been made in the materials utilized and safety features added. This equipment became the best option for numerous indoor retail establishments which 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 and its portability. Moreover, the scissor lift provides the only industrial platforms which could be retracted and can fit into the corner of the building.
