Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are particularly made for those projects directly overhead. Scissor Lifts are designed with a series of crisscrossing linked supports. 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 propels the unit vertically. If the equipment is hydraulically or pneumatically powered, lowering of the platform could be achieved by easily opening a valve in order to release the pressure.
There are a large array of scissor lift types which differ from outdoor rough terrain models to indoor models. The rough terrain scissor lift is made specially for construction operations. The rough terrain types are specially outfitted with stronger and more reliable tires which run by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are usually smaller models which depend upon screw threads or rack-and-pinion to elevate the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they could lift. Mostly, these lift types are utilized for maintenance tasks like for instance indoor applications and changing light bulbs.
The very first scissor lift was build 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 machine became the ideal alternative for numerous indoor retail establishments which were beginning to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become known and sought after for its portability as well as its effectiveness. In addition, the scissor lift provides the only industrial platforms which could be retracted and can fit into the corner of the building.
