Scissor Lifts
Scissor Lifts are particularly made for working on projects directly overhead because they are only capable of lifting on a vertical plane. Scissor Lifts are designed of a series of linked and folding supports which crisscross in an "x" pattern. The pressure should 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 that vertically propels the unit. If the equipment is hydraulically or pneumatically powered, lowering of the platform could be done by simply opening a valve in order to release the pressure.
There are a large variety of scissor lift models which vary from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed specifically for construction applications. The rough terrain models are specially equipped with stronger and more reliable tires that are powered by diesel or gas engines.
4 Mechanical Lifts
Generally, mechanical lifts are smaller models that use screw threads or rack-and-pinion symptoms to lift the platform. The mechanical lifts are limited in the amount of weight they can lift and the heights they can extend to. Mainly, these lift models are used for maintenance tasks like for example indoor applications and changing light bulbs.
The very first scissor lift was made in the 1970s. The fundamental design is still utilized, even though many improvements have been made in the materials utilized and safety features added. This machine became the ideal choice for many indoor retail establishments that were beginning to expand their inventory. The scissor lift is like the forklift. The scissor lift has become well-known and sought after for its portability as well as its effectiveness. Additionally, the scissor lift provides the only industrial platforms which could be retracted and could fit into the corner of the building.
