ASME B20.1-2006 pdf free download.Safety Standard for Conveyors and Related Equipment
limit switch: an electrical device by which the movementof a conveyor and allied equipment may be controlledwithin predetermined limits.
nip point: a point at which a machine element movingin line meets a rotating element in such a manner thatit is possible to nip., pinch, squeeze, or entrap a personor objects coming into contact with one of the two mem-bers.The same definition holds for the similar pointwith respect to two rotating parts or two convergingparts in linear movement.
operator’s station: location at which actuators are placedfor the purpose of starting, stopping, reversing, or other-wise controlling the conveyor or system of conveyorsin the course of normal operation.
overload device: a mechanical or electrical device designedto disconnect the driven equipment from the drivingequipment in event of an overload on the conveyor.platform: a working space for persons,elevated abovethe surrounding floor or ground (such as a balcony) forthe operation of machinery and equipment.
prevent: when used in a context such as prevent accessor prevent physical contact, means to impede or block;when used in the context such as prevent injury, meansto reduce the chances of but does not imply that aninjury cannot occur.
qualified person: a person who, by possession of a recog-nized degree or certificate of professional standing orby extensive knowledge, training, and experience, hassuccessfully demonstrated his / her ability to solve prob-lems relating to the subject matter and work.
rail:
(a) one of the longitudinal members in a conveyorframe
(b)the supporting surface under the wheels or rollersof a chain conveyor
(c) the supporting track for equipment mounted onwheels,such as belt tripper, weigh larry, etc.
(d) the vertical members that guide the pendant trays,cars, or carriers in a suspended vertical tray conveyorrail clamp: an attachment or device for clamping a mobileconveyor or belt tripper to the rail to hold it in a ixedlocation.
rail sfop: a stop mounted on the conveyor rails to limitthe travel of traversing machinery.
railing guard (guardrail): a structure consisting of rails and posts, including top rail, post, and, where required, . toeboards. rated capacity: the capacity at the rated speed, as established by the manufacturer or a qualified person, at which safe and satisfactory service can be expected.
rated speed: the speed of the conveyor, as established by the manufacturer or a qualified person, at which safe and satisfactory service can be expected. . remote control: any system of controls in which the actuator is situated in a remote location. remote location: any location, with respect to the conveyor, from which the presence or position of personnel relative to the conveyor cannot be readily determined from the operator ‘s station. roller:
(a) a revolving cylinder or wheel over which some- thing is moved. The face may be straight, tapered, crowned, concave, or flanged and corrugated, ribbed, or fluted (b) a component part or roller chain in which it may serve only to reduce frictional loss occurring as the chain passes over the sprockets. Rollers may also serve as the rolling support for the chain and the load being conveyed (c) the rotating element upon which a conveyor belt or chain or the object being transported is carried roller turn: a series of vertical rollers mounted in a frame to guide conveyor chain around a horizontal curve.
safety device: a mechanism or an arrangement placed in use for the specific purposes of preventing an unsafe condition, preventing the continuation of an unsafe condition, warning of an unsafe condition, or limiting or eliminating the unsafe effects of a possible condition. shall: as used in the context of a provision of this Stan- dard, indicated that the provision is mandatory and must be followed.
shear point or line: the point at which, or the line along which, a moving part meets or passes close enough to a stationary or moving part or object so that part of the human body can be caught, trapped, or pinched between them.ASME B20.1 pdf download.ASME B20.1-2006 pdf free download
