Scissor Lifts
Scissor Lifts are just capable of lifting on a vertical plane and are specifically made for those projects directly overhead. Scissor Lifts are designed 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 extends the crossing pattern which propels the unit vertically. If the equipment is pneumatically or hydraulically powered, lowering of the platform could be achieved by simply opening a valve in order to release the pressure.
There are a wide array of scissor lift types that differ from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed particularly for construction operations. The rough terrain models are particularly outfitted with stronger and more reliable tires that are powered by gas or diesel motors.
4 Mechanical Lifts
Mechanical lifts are generally smaller models that rely on screw threads or rack-and-pinion to lift the platform. The mechanical lifts are limited in the amount of weight they can lift and the heights they could extend to. Mainly, these lift types are used for maintenance jobs like for instance indoor applications and changing light bulbs.
The first scissor lift was build 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 particular equipment became the best alternative for many indoor retail establishments that were starting to expand their inventory. The scissor lift is a relative to the forklift. The scissor lift has become sought after and known for its portability as well as its effectiveness. Additionally, the scissor lift offers the only industrial platforms which could be retracted and can fit into the corner of the building.
