Scissor Lifts
Scissor Lifts are particularly 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 that crisscross in an "x" pattern. The pressure must 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 machine is hydraulically or pneumatically powered, lowering of the platform can be achieved by simply opening a valve in order to release the pressure.
There are a large variety of scissor lift models which differ from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed specifically for construction applications. The rough terrain models are specifically equipped with more reliable and stronger tires which operate by diesel or gas motors.
4 Mechanical Lifts
Usually, mechanical lifts are smaller models which use screw threads or rack-and-pinion symptoms to lift the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they are able to lift. Mainly, these types of lifts are utilized for maintenance jobs like for instance indoor applications and changing light bulbs.
The very first scissor lift was made during the 1970s. The fundamental design is still used, even if lots of improvements have been made in the materials utilized and safety features added. This particular machine became the perfect alternative for numerous indoor retail establishments that were starting to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become sought after and well-known for its portability and its effectiveness. Additionally, the scissor lift offers the only industrial platforms that could be retracted and can fit into the corner of the building.
