Scissor Lifts
Scissor Lifts are just 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 must 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 propels the unit vertically. If the equipment is pneumatically or hydraulically powered, lowering of the platform could be done by easily opening a valve to be able to release the pressure.
There are a large array of scissor lift types which vary from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed specifically for construction operations. The rough terrain types are specifically equipped with more reliable and stronger tires which operate by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are generally smaller models which depend upon screw threads or rack-and-pinion to raise the platform. The mechanical lifts are limited in the heights they can extend to and the amount of weight they can carry. Mainly, these lift types are utilized for maintenance jobs like changing light bulbs and indoor applications.
The first scissor lift was build in the 1970s. The basic design is still used, even if many improvements have been made in the materials utilized and safety features added. This machine became the perfect alternative for lots of indoor retail establishments which were beginning to expand their inventory. The scissor lift is like the forklift. The scissor lift has become sought after and well-known for its portability as well as its effectiveness. Moreover, the scissor lift provides the only industrial platforms which could be retracted and able to fit into the corner of the building.
