Scissor Lifts
Scissor Lifts are specifically made for working on projects directly overhead because they are just 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 has to 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 pneumatically or hydraulically powered, lowering of the platform could be achieved by easily opening a valve to be able to release the pressure.
There are various scissor lift models. They could differ from indoor models to those models specially made for rough terrain which are better suited for different construction operations. The rough terrain types are specially equipped with stronger and more reliable tires which are powered by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are normally smaller models that rely upon rack-and-pinion or screw threads to elevate the platform. The mechanical lifts are limited in the amount of weight they could carry and the heights they could extend to. Mainly, these lift types are utilized for maintenance tasks like indoor applications and changing light bulbs.
The first scissor lift was build in the 1970s. The basic design is still utilized, even if lots of improvements have been made in the materials utilized and safety features added. This machine became the perfect option for numerous indoor retail establishments that were starting to expand their inventory. The scissor lift is like the forklift. The scissor lift has become known and sought after for its effectiveness and its portability. Furthermore, the scissor lift provides the only industrial platforms which could be retracted and could fit into the corner of the building.
