Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead because they are only capable of lifting on a vertical plane. Scissor Lifts are made 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 propels the unit vertically. If the machinery is pneumatically or hydraulically powered, lowering of the platform could be achieved by easily opening a valve to be able to release the pressure.
There are a wide variety of scissor lift types that vary from indoor models to outdoor rough terrain models. The rough terrain scissor lift is made specially for construction operations. The rough terrain models are specifically equipped with stronger and more dependable tires which operate by diesel or gas engines.
4 Mechanical Lifts
Normally, mechanical lifts are smaller models that utilize screw threads or rack-and-pinion symptoms to elevate the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they could lift. Mostly, these types of lifts are used for maintenance jobs like changing light bulbs and indoor tasks.
The very first scissor lift was build in the 1970s. The fundamental design is still utilized, even if a lot of improvements have been made in the materials used and safety features added. This particular machine became the perfect choice for numerous indoor retail establishments which were starting to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become well-known and sought after for its effectiveness and its portability. Additionally, the scissor lift offers the only industrial platforms that could be retracted and could fit into the corner of the building.
