Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead since they are just capable of lifting on a vertical plane. Scissor Lifts are made of a series of linked and folding 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 propels the unit vertically. If the equipment is hydraulically or pneumatically powered, lowering of the platform can be done by simply opening a valve to be able to release the pressure.
There are a wide array of scissor lift models that differ from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed specially for construction applications. The rough terrain types are specifically outfitted with stronger and more dependable tires that operate by diesel or gas engines.
4 Mechanical Lifts
Mechanical lifts are usually smaller models that depend on screw threads or rack-and-pinion to raise the platform. The mechanical lifts are limited in the amount of weight they could carry and the heights they could extend to. Mainly, these types of lifts are used for maintenance tasks such as indoor applications and changing light bulbs.
The very first scissor lift was made during the 1970s. The basic design is still utilized, even though many improvements have been made in the materials used and safety features added. This machinery became the perfect alternative for many indoor retail establishments which were beginning to expand their inventory. The scissor lift is a relative to 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 which could be retracted and can fit into the corner of the building.
