Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead as 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 has 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 extends the crossing pattern which propels the unit vertically. If the machinery is hydraulically or pneumatically powered, lowering of the platform could be done by simply opening a valve in order to release the pressure.
There are a variety of scissor lift models. They can vary from indoor models to those types particularly made for rough terrain that are better suitable for different construction applications. The rough terrain types are particularly outfitted with more dependable and stronger tires which are powered by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are generally 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 can lift and the heights they could extend to. Mainly, these lift types are used for maintenance tasks such as indoor tasks and changing light bulbs.
In the 1970s, the first scissor lifts were built. 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 machine became the best choice 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 sought after and known for its effectiveness and its portability. Moreover, the scissor lift provides the only industrial platforms that could be retracted and can fit into the corner of the building.
