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 designed with a series of crisscrossing linked supports. The pressure has 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 machine is hydraulically or pneumatically powered, lowering of the platform could be done by easily opening a valve in order to release the pressure.
There are various scissor lift models. They can differ from indoor models to those types specially designed for rough terrain that are better suited for various construction applications. The rough terrain types are particularly outfitted with stronger and more dependable tires that operate by diesel or gas engines.
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 amount of weight they can carry and the heights they could extend to. Mainly, these types of lifts are used for maintenance tasks such as changing light bulbs and indoor tasks.
The first scissor lift was made during the 1970s. The fundamental design is still utilized, even though a lot of improvements have been made in the materials used and safety features added. This particular machine became the ideal choice for many indoor retail establishments which 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 and its effectiveness. In addition, the scissor lift offers the only industrial platforms that could be retracted and can fit into the corner of the building.
