Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead since they are just 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 should 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 propels the unit vertically. If the machine is pneumatically or hydraulically powered, lowering of the platform can be achieved by easily opening a valve in order to release the pressure.
There are various scissor lift models. They can differ from indoor models to those models specially designed for rough terrain that are better suited for different construction applications. The rough terrain models are particularly outfitted with stronger and more dependable tires that operate by diesel or gas engines.
4 Mechanical Lifts
Mechanical lifts are usually smaller models which rely on rack-and-pinion or screw threads to raise the platform. The mechanical lifts are limited in the amount of weight they are able to lift and the heights they can extend to. Mainly, these types of lifts are used for maintenance tasks like for instance changing light bulbs and indoor tasks.
During the 1970s, the very first scissor lifts were built. Even if numerous improvements have been made ever since that time in the categories of safety and materials, the essential original design is still normally used. This particular equipment became the perfect alternative for many indoor retail establishments which were beginning to expand their inventory. The scissor lift is like the forklift. The scissor lift has become sought after and well-known for its portability as well as its effectiveness. Moreover, the scissor lift offers the only industrial platforms that could be retracted and could fit into the corner of the building.
