Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead since 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 must 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 that vertically propels the unit. If the machinery is pneumatically or hydraulically powered, lowering of the platform could be done by simply opening a valve in order to release the pressure.
There are a wide array of scissor lift models which differ from indoor models to outdoor rough terrain models. The rough terrain scissor lift is made specially for construction operations. The rough terrain types are specifically equipped with more reliable and stronger tires which operate by diesel or gas engines.
4 Mechanical Lifts
Usually, mechanical lifts are smaller models which use rack-and-pinion or screw threads symptoms to lift the platform. The mechanical lifts are limited in the amount of weight they could lift and the heights they could extend to. Mainly, these types of lifts are used for maintenance tasks like indoor tasks and changing light bulbs.
The very first scissor lift was made in the 1970s. The fundamental design is still used, even if lots of improvements have been made in the materials utilized and safety features added. This equipment became the ideal option 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 able to fit into the corner of the building.
