Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are specifically made for those projects directly overhead. Scissor Lifts are made with a series of crisscrossing linked supports. 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 elongates the crossing pattern that vertically propels the unit. If the machine is hydraulically or pneumatically powered, lowering of the platform could be achieved by easily opening a valve in order to release the pressure.
There are a wide variety of scissor lift types that vary from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed specifically for construction operations. The rough terrain types are particularly outfitted with stronger and more reliable tires which operate by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are usually smaller models that rely on rack-and-pinion or screw threads to raise the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they are able to lift. Mostly, these lift models are used for maintenance jobs like for example indoor applications and changing light bulbs.
The first scissor lift was build in the 1970s. The fundamental design is still utilized, even though a lot of improvements have been made in the materials utilized and safety features added. This machine became the perfect alternative for many indoor retail establishments which were beginning to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become known and sought after for its effectiveness as well as its portability. Moreover, the scissor lift provides the only industrial platforms which could be retracted and could fit into the corner of the building.
