Scissor Lifts
Scissor Lifts are particularly made for working on projects directly overhead as they are only capable of lifting on a vertical plane. Scissor Lifts are designed of a series of linked and folding supports that crisscross in an "x" pattern. The pressure has 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 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 designed particularly for construction operations. The rough terrain types are specially outfitted with more reliable and stronger tires that run by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are generally smaller models which depend upon rack-and-pinion or screw threads to elevate the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they could lift. Mostly, these lift models are utilized for maintenance jobs such as indoor applications and changing light bulbs.
The first scissor lift was build during the 1970s. The fundamental design is still utilized, even if lots of improvements have been made in the materials utilized and safety features added. This equipment became the best choice for many indoor retail establishments that were beginning 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 as well as its effectiveness. Furthermore, the scissor lift provides the only industrial platforms that could be retracted and can fit into the corner of the building.
