Scissor Lifts
Scissor Lifts are specifically 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 linked and folding supports that crisscross in an "x" pattern. The pressure needs to be applied to the outside of the lowest set of supports in order for the unit to rise up into the air. This process extends the crossing pattern which vertically propels the unit. If the machine is pneumatically or hydraulically powered, lowering of the platform can be achieved by easily opening a valve in order to release the pressure.
There are a large variety of scissor lift models which differ from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed particularly for construction applications. The rough terrain models are specially outfitted with more dependable and stronger tires that run by diesel or gas engines.
4 Mechanical Lifts
Mechanical lifts are usually smaller models which depend on rack-and-pinion or screw threads to elevate the platform. The mechanical lifts are limited in the amount of weight they are able to carry and the heights they can extend to. Mainly, these lift models are used for maintenance jobs such as indoor applications and changing light bulbs.
In the 1970s, the very first scissor lifts were made. Even if several improvements have been made ever since that time in the categories of safety and materials, the essential original design is still often utilized. This particular machinery became the perfect alternative for numerous 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 well-known for its effectiveness as well as its portability. Furthermore, the scissor lift provides the only industrial platforms that could be retracted and able to fit into the corner of the building.
