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 needs to 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 could be done by simply opening a valve in order to release the pressure.
There are a variety of scissor lift types. They could vary from indoor models to those models particularly made for rough terrain which are better suited for various construction applications. The rough terrain models are particularly outfitted with more dependable and stronger tires that run by gas or diesel motors.
4 Mechanical Lifts
Mechanical lifts are usually smaller models which rely on rack-and-pinion or screw threads to raise the platform. The mechanical lifts are limited in the amount of weight they can lift and the heights they can extend to. Mostly, these types of lifts are utilized for maintenance jobs such as changing light bulbs and indoor applications.
The very first scissor lift was made in the 1970s. The fundamental design is still used, even though many improvements have been made in the materials used and safety features added. This equipment became the best option for many indoor retail establishments which were beginning to expand their inventory. The scissor lift is a relative to the forklift. The scissor lift has become well-known and sought after for its portability and its effectiveness. In addition, the scissor lift provides the only industrial platforms which could be retracted and able to fit into the corner of the building.
