Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead as they are only capable of lifting on a vertical plane. Scissor Lifts are designed of a series of folding and linked supports which crisscross in an "x" pattern. 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 which vertically propels the unit. If the machine is hydraulically or pneumatically powered, lowering of the platform can be done by easily opening a valve to be able to release the pressure.
There are various scissor lift models. They can differ from indoor models to those models specifically made for rough terrain which are better suited for various construction applications. The rough terrain models are specially outfitted with more reliable and stronger tires which run by gas or diesel motors.
4 Mechanical Lifts
Usually, mechanical lifts are smaller models that use 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 can lift. Mainly, these types of lifts are utilized for maintenance tasks like for example indoor applications and changing light bulbs.
The very first scissor lift was build in the 1970s. The basic 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 perfect alternative for many indoor retail establishments which were starting to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become sought after and 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.
