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 extends the crossing pattern that propels the unit vertically. If the equipment 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 a large array of scissor lift types which vary from indoor models to outdoor rough terrain models. The rough terrain scissor lift is made specially for construction applications. The rough terrain types are particularly outfitted with stronger and more reliable tires which operate by gas or diesel engines.
4 Mechanical Lifts
Usually, mechanical lifts are smaller models which utilize screw threads or rack-and-pinion 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 carry. Mainly, these lift types are used for maintenance jobs such as indoor applications and changing light bulbs.
The first scissor lift was made during the 1970s. The basic design is still used, even if many improvements have been made in the materials utilized and safety features added. This machinery became the best alternative 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 well-known and sought after for its effectiveness as well as its portability. Furthermore, the scissor lift offers the only industrial platforms that could be retracted and can fit into the corner of the building.
