Scissor Lifts
Scissor Lifts are only capable of lifting on a vertical plane and are specially made for those projects directly overhead. Scissor Lifts are designed 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 elongates the crossing pattern which vertically propels the unit. 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 a variety of scissor lift models. They can vary from indoor models to those types specially made for rough terrain which are better suitable for different construction operations. The rough terrain models are specially equipped with stronger and more reliable tires which run by gas or diesel motors.
4 Mechanical Lifts
Mechanical lifts are normally smaller models which depend on screw threads or rack-and-pinion to raise the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they can carry. Mostly, these types of lifts are utilized for maintenance tasks like for instance indoor tasks and changing light bulbs.
The very first scissor lift was build during the 1970s. The fundamental design is still utilized, even if many improvements have been made in the materials utilized and safety features added. This machinery became the perfect choice for many indoor retail establishments that were beginning 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. In addition, the scissor lift offers the only industrial platforms that could be retracted and could fit into the corner of the building.
