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 designed of a series of folding and linked supports which crisscross in an "x" pattern. The pressure should be applied to the outside of the lowest set of supports in order for the unit to rise up into the air. This process elongates the crossing pattern that propels the unit vertically. If the equipment is hydraulically or pneumatically powered, lowering of the platform can be achieved by simply opening a valve to be able to release the pressure.
There are various scissor lift models. They can differ from indoor models to those models specially designed for rough terrain which are better suited for different construction applications. The rough terrain types are specially equipped with stronger and more reliable tires that operate by gas or diesel motors.
4 Mechanical Lifts
Mechanical lifts are usually smaller models which depend on rack-and-pinion or screw threads to lift the platform. The mechanical lifts are limited in the heights they could extend to and the amount of weight they could lift. Mostly, these types of lifts are utilized for maintenance tasks like for example changing light bulbs and indoor tasks.
The very first scissor lift was build in the 1970s. The basic design is still utilized, even if a lot of improvements have been made in the materials utilized and safety features added. This machine became the perfect choice for a lot of indoor retail establishments that were starting to expand their inventory. The scissor lift is a relative to the forklift. The scissor lift has become sought after and well-known for its portability as well as its effectiveness. Additionally, the scissor lift provides the only industrial platforms which could be retracted and able to fit into the corner of the building.
