Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are specifically made for those projects directly overhead. Scissor Lifts are made with a series of crisscrossing linked supports. 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 extends the crossing pattern that propels the unit vertically. If the machinery is hydraulically or pneumatically powered, lowering of the platform can be achieved by easily opening a valve in order to release the pressure.
There are various scissor lift models. They could differ from indoor models to those types specially made for rough terrain which are better suitable for various construction operations. The rough terrain models are specially outfitted with more dependable and stronger tires which are powered by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are generally smaller models which depend on screw threads or rack-and-pinion to lift the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they can carry. Mostly, these kinds of lifts are utilized for maintenance jobs like indoor applications and changing light bulbs.
The first scissor lift was build during the 1970s. The fundamental design is still utilized, even if lots of improvements have been made in the materials utilized and safety features added. This machinery became the perfect choice for lots of indoor retail establishments that were starting to expand their inventory. The scissor lift is like the forklift. The scissor lift has become sought after and 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.
