Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead because 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 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 extends the crossing pattern which propels the unit vertically. If the equipment is hydraulically or pneumatically powered, lowering of the platform can be done by easily opening a valve in order to release the pressure.
There are various scissor lift types. They could vary from indoor models to those types specially made for rough terrain which are better suited for different construction operations. The rough terrain types are specially equipped with more dependable and stronger tires that run by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are normally smaller models which depend upon screw threads or rack-and-pinion to raise the platform. The mechanical lifts are limited in the amount of weight they could lift and the heights they could extend to. Mainly, these types of lifts are utilized for maintenance tasks like for example indoor tasks and changing light bulbs.
The first scissor lift was build during the 1970s. The basic design is still utilized, even if a lot of improvements have been made in the materials used and safety features added. This particular machinery became the perfect alternative for numerous 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 that could be retracted and can fit into the corner of the building.
