Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead because they are just capable of lifting on a vertical plane. Scissor Lifts are made of a series of folding and linked 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 elevate into the air. This process extends 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 in order to release the pressure.
There are a large array of scissor lift models that vary from outdoor rough terrain models to indoor models. The rough terrain scissor lift is made specially for construction operations. The rough terrain models are specially outfitted with stronger and more dependable tires which are powered by diesel or gas motors.
4 Mechanical Lifts
Generally, mechanical lifts are smaller models that utilize rack-and-pinion or screw threads symptoms to elevate the platform. The mechanical lifts are limited in the amount of weight they could lift and the heights they could extend to. Mostly, these lift models are used for maintenance jobs like indoor tasks and changing light bulbs.
The first scissor lift was build during the 1970s. The fundamental design is still utilized, even though lots of improvements have been made in the materials used and safety features added. This machinery became the ideal choice for lots of indoor retail establishments that were beginning to expand their inventory. The scissor lift is a relative 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 can fit into the corner of the building.
