Lifting equipment can be classified according to its power source manual, electrical, pneumatic, hydraulic or petrol or diesel. 

With a volume-pneumatic test, mechanics can detect defects in the parts due to incorrect replacement parts, incorrect machining, corrosion, or weak springs. Each of these problems can be discovered by such characteristics as early simmer, only a partial lift or leakage after the test. Defects such as inadvertently installing a spring too strong for the set pressure can be detected by short blow-down or chatter. Competent SRV test craftsmen can pinpoint defects with this type of test equipment. 

Materials-handling equipment is logically divided into continuous and batch types, and into classes for the handling of liquids, solids, and gases. Liquids and gases are handled by means of pumps and blowers in pipes, flumes, and ducts and in containers such as drums, cylinders, and tank cars. Solids may be handled by conveyors, bucket elevators, chutes, lift trucks, and pneumatic systems. The selection of materials-handling equipment depends upon the cost and the work to be done. Factors that must be considered in selecting such equipment include ... 

The dryers may be of the open-center type or the center-fill type. The former are equipped with lifting vanes or flights on the inside shell to carry fuel up the sides and disperse in the hot gas stream. In the open dryers the diameter is limited to about 2.5 m, and these provide a cheap and reliable system with low horsepower requirement. In the center-fill system, an internal structure helps to pneumatically convey the particles within the dryer. The center-fill dryer processes wet fuel according to its density. Particles of a particular... 

Hot-bar welding is a technique for the sealing of films. A heated metal bar applies pressure to the films, softens the plastic at the joint and forms a weld. The equipment consists of one or two electrically heated bars, one of which is hinged for the insertion and removal of the films. The film is placed on the base bar, the upper bar is brought down and pressure is applied either mechanically by the operator, or pneumatically. After the required weld time, the bar is lifted to release the joined films. The bars are often PTFE-coated to prevent molten polymer from adhering to them. 

Gaylord dumpers. This piece of equipment lifts and tilts a Gaylord to dump its contents into a holding hopper, usually designed to hold at least 2000 to 3000 lb of material. From this surge hopper, material is typically conveyed pneumatically to various use points.
