Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are specially made for those projects directly overhead. Scissor Lifts are designed with a series of crisscrossing linked supports. The pressure should be applied to the outside of the lowest set of supports in order for the unit to rise up into the air. This process elongates the crossing pattern that vertically propels the unit. If the equipment is pneumatically or hydraulically powered, lowering of the platform can be done by easily opening a valve to be able to release the pressure.
There are a large array of scissor lift types that vary from indoor models to outdoor rough terrain models. The rough terrain scissor lift is made specifically for construction applications. The rough terrain models are specifically equipped with stronger and more reliable tires which operate by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are generally smaller models that depend upon rack-and-pinion or screw threads to lift the platform. The mechanical lifts are limited in the amount of weight they are able to lift and the heights they could extend to. Mainly, these lift models are utilized for maintenance tasks like indoor applications and changing light bulbs.
During the 1970s, the first scissor lifts were made. Even though various improvements have been made since that time in the categories of materials and safety, the essential original design is still often utilized. This particular machine became the best choice for numerous indoor retail establishments that were starting to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become well-known and sought after for its portability and its effectiveness. Additionally, the scissor lift provides the only industrial platforms which could be retracted and can fit into the corner of the building.
