Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead since 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 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 elongates the crossing pattern that vertically propels the unit. If the equipment is hydraulically or pneumatically powered, lowering of the platform can be done by easily opening a valve to be able to release the pressure.
There are a wide array 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 types are particularly equipped with more dependable and stronger tires that operate by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are normally smaller models which rely upon rack-and-pinion or screw threads to lift the platform. The mechanical lifts are limited in the amount of weight they can lift and the heights they can extend to. Mainly, these types of lifts are used for maintenance tasks like changing light bulbs and indoor tasks.
During the 1970s, the very first scissor lifts were built. Even if various improvements have been made since that time in the categories of materials and safety, the basic original design is still often used. This particular machine became the perfect option for numerous indoor retail establishments that were starting to expand their inventory. The scissor lift is like the forklift. The scissor lift has become known and sought after for its portability as well as its effectiveness. In addition, the scissor lift offers the only industrial platforms that could be retracted and could fit into the corner of the building.
