Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead as they are only capable of lifting on a vertical plane. Scissor Lifts are made 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 elevate into the air. This process elongates the crossing pattern which vertically propels the unit. If the machinery is hydraulically or pneumatically powered, lowering of the platform can be done by simply opening a valve to be able to release the pressure.
There are a large variety of scissor lift types which differ from indoor models to outdoor rough terrain models. The rough terrain scissor lift is designed particularly for construction operations. The rough terrain types are particularly equipped with more reliable and stronger tires which are powered by gas or diesel engines.
4 Mechanical Lifts
Normally, mechanical lifts are smaller models that use rack-and-pinion or screw threads symptoms to raise the platform. The mechanical lifts are limited in the heights they could extend to and the amount of weight they could carry. Mainly, these types of lifts are utilized for maintenance tasks such as 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 particular machinery became the ideal option 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 well-known and sought after for its portability and its effectiveness. Additionally, the scissor lift provides the only industrial platforms that could be retracted and can fit into the corner of the building.
