Scissor Lifts
Scissor Lifts are particularly 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 has to be applied to the outside of the lowest set of supports in order for the unit to elevate into the air. This process extends the crossing pattern which vertically propels the unit. If the equipment is pneumatically or hydraulically powered, lowering of the platform can be achieved by easily opening a valve to be able to release the pressure.
There are various scissor lift models. They could vary from indoor models to those models particularly made for rough terrain that are better suitable for different construction applications. The rough terrain types are specially equipped with stronger and more dependable tires which are powered by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are usually smaller models which depend on screw threads or rack-and-pinion to elevate the platform. The mechanical lifts are limited in the amount of weight they are able to lift and the heights they can extend to. Mostly, these kinds of lifts are utilized for maintenance tasks like for example changing light bulbs and indoor tasks.
During the 1970s, the first scissor lifts were made. Even if several improvements have been made since that time in the categories of safety and materials, the essential original design is still often utilized. This particular machine became the ideal alternative 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 known and sought after for its portability and its effectiveness. Furthermore, the scissor lift offers the only industrial platforms that could be retracted and could fit into the corner of the building.
