Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead because they are just capable of lifting on a vertical plane. Scissor Lifts are made of a series of folding and linked 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 elevate into the air. This process elongates the crossing pattern which propels the unit vertically. If the machinery is pneumatically or hydraulically powered, lowering of the platform can be achieved by simply opening a valve to be able to release the pressure.
There are a wide array of scissor lift types which vary from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed specially for construction operations. The rough terrain types are specifically equipped with more reliable and stronger tires that are powered by gas or diesel engines.
4 Mechanical Lifts
Usually, mechanical lifts are smaller models which use rack-and-pinion or screw threads symptoms to lift 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 lift models are utilized for maintenance tasks like indoor tasks and changing light bulbs.
In the 1970s, the very first scissor lifts were built. Even though numerous improvements have been made ever since that time in the categories of safety and materials, the essential original design is still often used. This equipment became the best alternative for many indoor retail establishments which were starting to expand their inventory. The scissor lift is like the forklift. The scissor lift has become sought after and well-known for its portability and 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.
