Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead since they are just capable of lifting on a vertical plane. Scissor Lifts are made of a series of folding and linked supports that crisscross in an "x" pattern. The pressure has 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 extends the crossing pattern that vertically propels the unit. If the machinery 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 various scissor lift models. They could vary from indoor models to those types specifically made for rough terrain which are better suitable for various construction applications. The rough terrain types are specifically equipped with more dependable and stronger tires which operate by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are normally smaller models which depend upon rack-and-pinion or screw threads to elevate the platform. The mechanical lifts are limited in the heights they could extend to and the amount of weight they could lift. Mainly, these kinds of lifts are utilized for maintenance jobs like indoor tasks and changing light bulbs.
The first scissor lift was made in the 1970s. The basic design is still used, even if lots of improvements have been made in the materials utilized and safety features added. This particular equipment became the ideal alternative for many indoor retail establishments that were starting to expand their inventory. The scissor lift is similar to the forklift. The scissor lift has become well-known and sought after for its effectiveness and its portability. In addition, the scissor lift offers the only industrial platforms that could be retracted and can fit into the corner of the building.
