Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead since they are only capable of lifting on a vertical plane. Scissor Lifts are designed of a series of linked and folding supports which crisscross in an "x" pattern. The pressure needs to be applied to the outside of the lowest set of supports in order for the unit to rise up into the air. This process elongates the crossing pattern that vertically propels the unit. If the machinery is pneumatically or hydraulically powered, lowering of the platform could be done by easily opening a valve in order to release the pressure.
There are a wide variety of scissor lift models which vary from indoor models to outdoor rough terrain models. The rough terrain scissor lift is designed particularly for construction applications. The rough terrain types are specially equipped with stronger and more reliable tires which run by gas or diesel motors.
4 Mechanical Lifts
Generally, mechanical lifts are smaller models which utilize rack-and-pinion or screw threads symptoms to lift the platform. The mechanical lifts are limited in the amount of weight they could lift and the heights they can extend to. Mostly, these lift types are used for maintenance tasks like indoor applications and changing light bulbs.
During the 1970s, the very first scissor lifts were made. Even if numerous improvements have been made ever since that time in the categories of safety and materials, the basic original design is still usually utilized. This equipment became the ideal option for many 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 and its portability. Additionally, the scissor lift provides the only industrial platforms that could be retracted and can fit into the corner of the building.
