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 made of a series of linked and folding supports that 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 extends the crossing pattern which propels the unit vertically. If the machine 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 variety of scissor lift models. They could vary from indoor models to those types particularly designed for rough terrain which are better suitable for various construction operations. The rough terrain models are specifically equipped with stronger and more dependable tires that run by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are normally smaller models that depend upon screw threads or rack-and-pinion to raise the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they could carry. Mainly, these lift types are used for maintenance tasks such as changing light bulbs and indoor tasks.
In the 1970s, the first scissor lifts were built. Even if several improvements have been made since that time in the categories of materials and safety, the basic original design is still often utilized. This machine became the ideal option for numerous indoor retail establishments which were beginning to expand their inventory. The scissor lift is like the forklift. The scissor lift has become known and sought after for its effectiveness and its portability. Additionally, the scissor lift provides the only industrial platforms that could be retracted and could fit into the corner of the building.
