ASME B20.1:2006 pdf download Safety Standard for Conveyors and Related Equipment
DEFINITIONS14
actuafor: a device that initiates the action of controls orcontrollers and is manually operated. The actuator maybe a push button, toggle switch, foot pedal, hand leverhand-set timer, or any other device that performs thedescribed function.
antirunawny: a safety device to stop a declining conveyorand thus prevent moving away in the event of a mechanical or electrical failure.
apron pan: one of a series of overlapping or interlockingplates or shapes that, together with others, form theconveyor bed.
aufomtatically controlled: describes the operation be theaction of a mechanism that is initiated by some imper-sonal influence, such as a conveyor that is started by alow-level bin indicator.backstop: a mechanical device to prevent reversal of aloaded conveyor under action of gravity when forwardtravel is interrupted.bed:
(a) that part of a conveyor upon which the load orcarrying medium rests or slides while being conveyed(b) in bulk material conveyors, the mass of materialbeing conveyedbelf idler: a roller or series of rollers that supports thebelt of a belt conveyor.
belt fripper: a device incorporating a system of pulleysthat causes the conveyor belt to discharge material atone or more points along the length of the conveyor.boont; a cantilevered member or structure that may behinged, fixed,or pivoted.
brake: a friction device for slowing down conveyor com-ponents, bringing conveyor equipment to a controlledstop, holding traveling or traversing equipment in aselected location, preventing reverse travel, and control-ing overspeed due to the action of gravity.
bunker: a large bin or compartment for storage of bulkmaterials
car tnloader: a type of conveyor characterized by a shallow, horizontal loading section that enables it to receiveand unload material from hopper bottom cars withoutrequiring a pit or other excavation.
carrier:
(a) a device attached to or hung from trolleys to sup!port 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 reciprocat-ing conveyor that supports the load
chain: a series of links pivotally joined together to form amedium for conveying or transmitting motion or power.General classes of chain common to conveyors aredetachable,pintle, combination,roller, rivetless,coil,inverted tooth, and bar link chains.
chute: a trough through which bulk materials or objectsare directed and lowered by gravity. The trough may beopen or enclosed, straight or curved.
confrol: the system governing the starting, stoppingdirection of motion, acceleration, speed, retardationidentification, and function of the moving member in apredetermined manner.
controller: an electromechanical device or assembly ofdevices for starting stopping, accelerating, or decelerat-ing a drive or serving to govern in some predeterminedmanner the power delivered to the drive.
conveying medium: that portion of a conveyor that movesor carries materials, packages, or objects.
