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 designed of a series of linked and folding supports that 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 extends the crossing pattern that vertically propels the unit. If the equipment is pneumatically or hydraulically powered, lowering of the platform could be done by simply opening a valve in order to release the pressure.
There are a wide variety of scissor lift models which vary from outdoor rough terrain models to indoor models. The rough terrain scissor lift is designed specifically for construction applications. The rough terrain types are specifically outfitted with stronger and more reliable tires which operate by diesel or gas motors.
4 Mechanical Lifts
Mechanical lifts are normally smaller models which depend on rack-and-pinion or screw threads to raise the platform. The mechanical lifts are limited in the amount of weight they could carry and the heights they can extend to. Mainly, these types of lifts are used for maintenance tasks such as indoor applications and changing light bulbs.
In the 1970s, the first scissor lifts were built. Even though various improvements have been made ever since that time in the categories of safety and materials, the basic original design is still normally utilized. This machine became the perfect alternative 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 portability and its effectiveness. Additionally, the scissor lift provides the only industrial platforms which could be retracted and can fit into the corner of the building.
