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 extends the crossing pattern that propels the unit vertically. If the equipment is hydraulically or pneumatically powered, lowering of the platform can be done by simply opening a valve in order to release the pressure.
There are various scissor lift types. They can vary from indoor models to those types specially made for rough terrain which are better suited for various construction operations. The rough terrain models are specially equipped with stronger and more reliable tires that run by diesel or gas motors.
4 Mechanical Lifts
Normally, mechanical lifts are smaller models that utilize rack-and-pinion or screw threads symptoms to elevate the platform. The mechanical lifts are limited in the heights they could extend to and the amount of weight they are able to lift. Mainly, these types of lifts are used for maintenance jobs such as indoor tasks and changing light bulbs.
The first scissor lift was build in the 1970s. The fundamental design is still utilized, even though lots of improvements have been made in the materials utilized and safety features added. This particular machinery became the best option for lots of indoor retail establishments which were beginning to expand their inventory. The scissor lift is a relative to the forklift. The scissor lift has become sought after and known for its effectiveness as well as its portability. Furthermore, the scissor lift offers the only industrial platforms which could be retracted and able to fit into the corner of the building.
