ASME B20.1-2006 pdf free download.Safety Standard for Conveyors and Related Equipment.
belt tripper: a device incorporating a system of pulleys that causes the conveyor belt to discharge material at one or more points along the length of the conveyor.
boom: a cantilevered member or structure that may be hinged, fixed, or pivoted.
brake: a friction device for slowing down conveyor components, bringing conveyor equipment to a controlled stop, holding traveling or traversing equipment in a selected location, preventing reverse travel, and controlling overspeed due to the action of gravity.
bunker: a large bin or compartment for storage of bulk materials.
car unloader: a type of conveyor characterized by a shallow, horizontal loading section that enables it to receive and unload material from hopper bottom cars without requiring a pit or other excavation.
(a) a device attached to or hung from trolleys to support the load
(b) the receptacle in which objects are placed for transmittal through a conveying system
(c) the moving part of a vertical or inclined reciprocating conveyor that supports the load
chain: a series of links pivotally joined together to form a medium for conveying or transmitting motion or power. General classes of chain common to conveyors are detachable, pintle, combination, roller, rivetless, coil, inverted tooth, and bar link chains.
chute: a trough through which bulk materials or objects are directed and lowered by gravity. The trough may be open or enclosed, straight or curved.
control: the system governing the starting, stopping, direction of motion, acceleration, speed, retardation, identification, and function of the moving member in a predetermined manner.
controller: an electromechanical device or assembly of devices for starting, stopping, accelerating, or decelerating a drive or serving to govern in some predetermined manner the power delivered to the drive.
conveying ,;iedium: that portion of a conveyor that moves or carries materials, packages, or objects.
conveyor: a horizontal, inclined, or vertical device for moving or transporting bulk material, packages, or objects in a path predetermined by the design of the device and having points of loading and discharge, fixed or selective. Included are skip hoists and vertical reciprocating 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, bucket drag lines, trenchers, platform elevators designed to carry passengers or an operator, manlifts, moving walks, moving stairways (escalators), highway or railway vehicles, cableways, tramways, dumbwaiters, pneuma tic conveyors, robots, or integral machine transfer devices.
conveyor belt: a belt used to carry materials and transmit the power required to move the load being conveyed.
conveyor screw: the material-propelling medium of a screw conveyor generally consisting of an assembly of helical flights mounted on a rotating pipe or shaft.
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, eleclrfied 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.
