conveyor, electrifiedmonorail:aconveyorconsistingofa networkoftracks orguide rails thatmaybe installed hori- zontally, vertically, inclined, orincombinationwithone or more self-propelled cars or trolleys that move indepen- dentlyunder automatic control from one pointto 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 ofa 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.
Bulk material is conveyed and elevated in a substan- tially 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, flight: a type ofconveyor comprised ofone or more endless propelling media, such as chain, to which flights are attached and a trough through which material is pushed by the flights. conveyor, folding belt: a bulk materials trough belt conveyor that has a longitudinally grooved belt cover.
These grooves allow the outer edges of the belt to form flaps. These flaps are folded over the conveyed product on the carry side of the conveyor enclosing the product.
The flaps are held in place on top of the product by containment idlers. Folding belt conveyors enclose the conveyed material on the carrying side and contain carryover material on the noncarrying side. conveyor, horizontal reciprocating: a conveyor that progressively advances material by a back-and-forth motion of its conveying medium. It may be equipped with hinged flights or tilting dogs or pushers.
These units operate generally in the range of 0 deg to 30 deg from the horizontal. conveyor, inclinedreciprocating: a reciprocatingpower- orgravity-actuatedunit(notdesignedto carrypassengers or an operator) that receives objects on a carrier.
These unitsoperateoninclinesgenerallyintherangeof30degto 70 deg from the horizontal. conveyor, live roller: a series of rollers over which objects are moved by the application of power to all or some of the rollers.
The power-transmitting medium is usually belting or chain. conveyor, material encapsulating: a bulk materials 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 notlimitedto, radial stackers, winged stackers, reclaiming conveyors, and shiploaders. These conveyors normally handle bulk material. conveyor, mobile hopper railcar/hopper bottom truck unloader: a specialty mobile conveyor characterized by a low-profile tail section designed to fit in the space between the top of rail and bottom of the railcar hopper outlet gate for unloading railcars or trucks.
conveyor, oscillating: a type of vibrating conveyor having 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 arrangement on both the 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 thatis not self-propelled, usually having supports that provide mobility. conveyor, power and free: a conveying system wherein theloadis carriedonatrolleyortrolleys thataremechani cally 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. The spur or subsidiary lines may or may not be powered. conveyor, pusher bar: two endless chains cross- connected at intervals by bars or rotatable pushers that propel the load along the bed or trough of the conveyor.
conveyor, reciprocating:aconveyorwherethecarrieror pusher moves forward and back, or up and down, in the same plane.
conveyor, roller: a series ofrollers supported in a frame over which objects are advanced manually, by gravity, or by power. conveyor,
roller slat: a slat conveyor using rollers for slats.ASME B20.1 pdf download.ASME B20.1-2018 pdf free download
