Scissor Lifts
Scissor Lifts are specially made for working on projects directly overhead because they are only capable of lifting on a vertical plane. Scissor Lifts are made of a series of linked and folding supports which crisscross in an "x" pattern. The pressure should 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 hydraulically or pneumatically powered, lowering of the platform can be done by easily opening a valve in order to release the pressure.
There are a variety of scissor lift types. They could vary from indoor models to those types specifically designed for rough terrain that are better suitable for various construction operations. The rough terrain types are specifically outfitted with more dependable and stronger tires that operate by gas or diesel engines.
4 Mechanical Lifts
Mechanical lifts are generally smaller models which rely upon screw threads or rack-and-pinion to elevate the platform. The mechanical lifts are limited in the heights they could extend to and the amount of weight they could lift. Mostly, these types of lifts are used for maintenance jobs such as indoor applications and changing light bulbs.
The very first scissor lift was build during the 1970s. The basic design is still utilized, even though many improvements have been made in the materials used and safety features added. This machine became the ideal alternative for lots of 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 effectiveness and its portability. In addition, the scissor lift offers the only industrial platforms that could be retracted and could fit into the corner of the building.
