ASME B20.1-2006 pdf – Safety Standard for Conveyors and Related Equipment.
conveyor, trolley: a series of trolleys supported from or within an overhead track and connected by endless propelling means, such as chain, cable, or other linkage, with loads usually suspended from the trolleys.
conveyor, vertical articulated: a type of vertical conveyor in which sections of articulated slat conveyor apron form rigid carriers for vertical movement in continuous flow The carriers are flexible in but one direction, and they assume a vertical position on the noncarrying run to minimize space requirements.
conveyor, vertical chain, opposed shelf type: two or more vertical elevating-conveying units opposed to each other. Each unit consists of one or more endless chains whose adjacent facing runs operate in parallel paths. Thus, each pair of opposing shelves or brackets receives objects (usually dish trays) and delivers them to any number of stations.
conveyor, vertical reciprocating: a reciprocating power- or gravity-actuated unit (not designed to carry passengers or an operator) that receives objects on a carrier and transmits these objects vertically between two or more levels.
conveyor, vibrating: a trough, tube, or other device flexibly supported and vibrated at a relatively high frequency and small amplitude to coiwey bulk material or objects, usually powered by an electrical or pneumatic impulse.
conveyor, zvheel: a series of wheels supported in a frame over which objects are moved manually or by gravity.
(a) a device across the path of a conveyor placed at an angle and designed to deflect objects
(b) a plate inserted in the trajectory of a hulk material discharge to change direction
drive: an assembly of the necessary structural, mechanical, and electrical parts that provides the motive power for a conveyor.
drum: a cylindrical or polygonal rim type of wheel around which cable, chain, belt, or other linkage may be wrapped. A drum may be drive or driving. The face may be smooth, grooved, fluted, or flanged.
dumbwaiter: a type of material-lifting device specifically limited to a platform area of 0.8 m2 (9 ft2) or less, inside car height of 1.2 m (4 ft) or less, and a hoistway door height of 1.24 m (4 ft 1 in.) or less.2
emergency stop: a stop arising from a sudden and unexpected need and not as a part of the normal operation.
emergency stop device: a device that can be actuated in an emergency situation to stop a conveyor,
enclosed: describes guarding of moving parts in such a manner that inadvertent physical contact by parts of the body is precluded as long as the guard or enclosure
remains in place. The guarding may make use of hinged, sliding, or removable doors for inspection or service.
(a) plain or shaped plates suitably made for attachment to the propelling medium of a flight conveyor.
(b) a term applied to any section of a conveyor in a tandem series.
gate: a device or structure by means of which the flow of material may be stopped or regulated; also, a section of conveyor equipped with a hinge mechanism for movable service, often called a hinged section.
(a) a coarse screen made of parallel or crossed bars to prevent passage of oversize material
(b) a series of parallel and crossed bars used as platform or walkway floors or as coverings for pits arid trenches over which traffic may pass. Generally removable to permit access to conveying equipment for servicing
(c) a series of parallel or cross bar units, or both, fastened to or propelled by the conveying medium, used for carrying large, lump-sized bulk material or objects. Generally used to permit passage of air for cooling or heat to maintain temperature
(a) a covering, barricade, grating, fence, or other form of barrier used to prevent inadvertent physical contact with operating components, such as gears, sprockets, chains, and belts
(b) a structure mounted below an overhead mounted conveyor to protect personnel from falling materials.
