Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead as they are only 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 rise up into the air. This process extends the crossing pattern that propels the unit vertically. If the machine is pneumatically or hydraulically powered, lowering of the platform can be done by simply opening a valve in order to release the pressure.
There are various scissor lift models. They could vary from indoor models to those types specially made for rough terrain that are better suitable for different construction applications. The rough terrain models are specially outfitted with stronger and more dependable tires which operate by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are generally smaller models that depend on rack-and-pinion or screw threads to raise the platform. The mechanical lifts are limited in the heights they could extend to and the amount of weight they can carry. Mainly, these types of lifts are utilized for maintenance tasks such as changing light bulbs and indoor applications.
The very first scissor lift was build in the 1970s. The fundamental design is still used, even if a lot of improvements have been made in the materials utilized and safety features added. This equipment became the ideal choice for many indoor retail establishments that were starting to expand their inventory. The scissor lift is like the forklift. The scissor lift has become well-known and sought after for its portability and its effectiveness. Additionally, the scissor lift provides the only industrial platforms that could be retracted and can fit into the corner of the building.
