Included are skip hoists andverticalrecipro- cating and inclined reciprocating conveyors. Typical exceptions are those devices known as industrial trucks, tractors, trailers, tiering machines (except pallet load tierers), cranes, hoists, power shovels, power scoops, bucketdraglines, trenchers, platformelevators designed to carry passengers or an operator, manlifts, moving walks, moving stairways (escalators), highway or rail- wayvehicles, cableways, tramways, dumbwaiters, pneu- matic conveyors, robots, or integral machine transfer devices. conveyor, apron: a conveyor in which a series of apron pans forms a moving bed. conveyor, belt: an endless fabric, rubber, plastic, leather, or metal belt operating over suitable drive, tail end, and bend terminals and over belt idlers or slider bed for handling bulk materials, packages, or objects placed directly upon the belt. conveyor, bucket: any type of conveyor in which the material is carried in a series of buckets. conveyor, chain: any type of conveyor in which one or more chains act as the conveying medium; a British term for trolley conveyor. conveyor, declining: a conveyor transporting down a slope. conveyor, electrified monorail: a conveyor consisting of a network of tracks or guide rails that may be installed horizontally, vertically, inclined, or in combination with one or more self-propelled cars or trolleys that move independently under automatic control from one point to another within the track network, carrying material in containers or by devices suspended from or attached to the cars or trolleys. conveyor, en masse: a conveyor, comprised of a series of skeleton or solid flights on an endless chain or other linkage, that operates in horizontal, inclined, or vertical paths within a closely fitted casing for the carrying run. Bulkmaterial is conveyed and elevated in a substantially continuous stream with a full cross section of the casing. conveyor, extendable: a conveyor that may be length- ened or shortened to suit operating needs. conveyor
conveyor, inclined reciprocating: a reciprocating power- or gravity-actuated unit (not designed to carry passen- gers or an operator) that receives objects on a carrier. These units operate on inclines generally in the range of 30 deg to 70 deg from the horizontal. conveyor, liveroller: a series ofrollers overwhichobjects are moved by the application of power to all or some ofthe rollers. The power-transmittingmediumis usually belting or chain. conveyor, materialencapsulating: abulkmaterials trough belt conveyor that has a belt(s) that completely encloses the conveyed product. conveyor, mobile: a conveyor, supported on a structure, that is movable under its own power and includes, but is not limited to, radial stackers, winged stackers, reclaiming conveyors, and shiploaders. These conveyors normally handle bulk material. conveyor, oscillating: a type of vibrating conveyor hav- ing a relatively low frequency and large amplitude of motion, usually powered by a rotating eccentric. conveyor, overland: a single or series of belt conveyors designed to carry bulk material across country, usually following the general contour of the land. conveyor, pipe: a bulk materials belt conveyor in which the belt is formed into a circular or oval cross section by the idler arrangementon boththe carrying and return sides. This design encloses the conveyed material on the carrying side and contains carryover material on the noncarrying side. conveyor, portable: a transportable conveyor that is not self-propelled, usually having supports that provide mobility. conveyor, power and free: a conveying system wherein theloadiscarriedonatrolleyortrolleys thataremechan- ically propelled through part of the system and may be gravity or manually propelled through another part. This arrangement provides a means of switching the free trolleys into and out of adjacent lines.
