Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are specially made for those projects directly overhead. Scissor Lifts are designed with a series of crisscrossing linked supports. The pressure needs 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 vertically propels the unit. 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 indoor models to outdoor rough terrain models. The rough terrain scissor lift is designed particularly for construction operations. The rough terrain types are particularly outfitted with stronger and more reliable tires which operate by gas or diesel engines.
4 Mechanical Lifts
Normally, mechanical lifts are smaller models that utilize screw threads or rack-and-pinion symptoms to elevate the platform. The mechanical lifts are limited in the amount of weight they are able to carry and the heights they could extend to. Mostly, these lift types are utilized for maintenance tasks like indoor applications and changing light bulbs.
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 used and safety features added. This particular machinery became the perfect option for many indoor retail establishments which were beginning to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become sought after and known for its effectiveness as well as its portability. Additionally, the scissor lift offers the only industrial platforms which could be retracted and able to fit into the corner of the building.
