ASME B20.1:2006 pdf free download Safety Standard for Conveyors and Related Equipment
corveyor belt: a belt used to carry materials and transmitthe power required to move the load being conveyed.conoeyor screw: the material-propelling medium of ascrew conveyor generally consisting of an assembly ofhelical flights mounted on a rotating pipe or shaft.conzeyor,apron: a conveyor in which a series of apronpans forms a moving bed.
conveyor,belf: an endless fabric, rubber, plastic, leather,or metal belt operating over suitable drive, tail end, andbend terminals and over belt idlers or slider bed forhandling bulk materials, packages, or objects placeddirectly upon the belt.
conoeyor, bucket: any type of conveyor in which the mate-rial is carried in a series of buckets.
conzeyor，chain: any type of conveyor in which one ormore chains act as the conveying medium; a British termfor trolley conveyor.
conveyor, declining: a conveyor transporting down aslope.
corveyor, electrified monorail: a conveyor consisting of anetwork of tracks or guide rails that may be installedhorizontally, vertically, inclined, or in combination withone or more self-propelled cars or trolleys that moveindependently under automatic control from one pointto another within the track network, carrying materialin containers or by devices suspended from or attachedto the cars or trolleys.
conzveyor, en wasse: a conveyor, comprised of a series of skeleton or solid flights on an endless chain or otherlinkage, 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 substantiallycontinuous stream with a full cross section of the casing-coroeyor, extendable; a conveyor that may be lengthenedor shortened to suit operating needs.
conveyor, fight: a type of conveyor comprised of one ormore endless propelling media,such as chain, to whichflights are attached and a trough through which materialis pushed by the flights.
conveyor, horizontal reciprocating: a conveyor that progres-sively advances material by a back-and-forth motion ofits conveying medium. It may be equipped with hingedflights or tilting dogs or pushers. These units operategenerally in the range of 0-30 deg from the horizontal.coYveyor, inclined reciprocating: a reciprocating powerorgravity-actuated unit (not designed to carry passengersor an operator) that receives objects on a carrier. Theseunits operate on inclines generally in the range of 30-70 deg from the horizontal.
conoeyor,live roller: a series of rollers over which objectsare moved by the application of power to all or someof the rollers.The power-transmitting medium is usuallybelting or chain.
conveyor, mobile: conveyor, supported on a structure,which is movable under its own power and includes,but is not limited to,radial stackers, winged stackers,reclaiming conveyors, and shiploaders.These conveyorsnormally handle bulk material.
conveyor, oscillating: a type of vibrating conveyor havinga relatively low frequency and large amplitude ofmotion, usually powered by a rotating eccentric.
conveyor，overland: a single or series of belt conveyorsdesigned to carry bulk material across country, usuallyfollowing the general contour of the land.
conoeyor，portable: a transportable conveyor that is notself-propelled, usually having supports that providemobility.
conoeyor, power and free: a conveying system wherein theload is carried on a trolley or trolleys that are mechani-cally propelled through part of the system and may begravity or manually propelled through another part.This arrangement provides a means of switching thefree trolleys into and out of adjacent lines. The spur orsubsidiary lines may or may not be powered.
conveyor, pusher bar: two endless chains cross-connectedat intervals by bars or rotatable pushers that propel theload along the bed or trough of the conveyor.
conzeyor,reciprocating: a conveyor where the carrier orpusher moves forward and back, or up and down,inthe same plane.
conveyor,roller: a series of rollers supported in a frameover which objects are advanced manually, by gravity,or by power.
conveyor, roller slat: a slat conveyor using rollers for slats.conveyor, screw: a conveyor screw revolving in a suitablyshaped stationary trough or casing fitted with hangers,trough ends, and other auxiliary accessories.
conveyor，shutfle: any conveyor，such as a belt,chain,apron, screw, etc., in a self-contained structure, movablein a defined path parallel to the flow of the material.conveyor, slat: a conveyor employing one or more endlesschains to which nonoverlapping, noninterlockingspaced slats are attached.
