ASME B30.25-2007 pdf free download.SCRAP AND MATERIAL HANDLERS Chapter 25-0 Scope, Definitions, and References
ballast: weight used to supplement the weight of the handler in providing stability for handling loads (the term “ballast” is normally associated with railmounted handlers). base (mounting): the structure on which the rotating upper-structure handler is mounted.
boom: first section ofa front, one end ofwhich is attached to the upper-structure. boom cylinder(s): the hydraulic cylinder(s) that move(s) the boom vertically in relation to the upper-structure. brake: a device used for retarding or stopping motion.
brake, parking: a system to prevent inadvertent move- ment of a stationary handler. brake, secondary: a system for stopping the handler upon service brake system failure. brake, service: a system for slowing and stopping the handler during travel operation. cab: a weatherproof housing that covers the operator’s station.
counterweight: weight used to supplement the weight of the handler in providing stability for handling loads.
daily: a work shift consisting of a period of 10 hr or less usage within a 24-hr period. designated person: a person selected or assigned by the employerorthe employer’s representative as beingcom- petent to perform specific duties.
front: consists of two or three structural members actu- ated by hydraulic cylinders that are affixed to the upperstructure formounting the attachment(see Figs. 6 and 7). jib: third section of a front, one end of which is attached to the arm.
jib cylinder(s): the hydraulic cylinder(s) that move(s) the jib in relation to the arm. lift capacity: ratings in pounds (kilograms) established by the manufacturer or assembler/modifier.
manufacturer: the entity that designs, fabricates, and assembles basic components. material: waste products processed for incineration and/or disposal. monthly: a period of 200 hr or less usage within a 30-day period.
outriggers: extendable or fixed members attached to the mounting base that are used to raise, level, and support the handler.
qualified operator: an operator who has met the requirements of this volume and has been appointed as an operator.
qualified person: a person who, by possession of a recognized degree in an applicable field, or certificate of professional standing, or who, by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter and work.
rail clamp: a tong-like metal device mounted on a loco- motive car, which can be connected to the track to pre- vent movement along the rail. safety sign: a visual alerting device in the form of a decal, label, placard, or other marking thatadvises the operator or others of the nature and the degree of the potential hazard(s).
It can also describe safety precautions or eva- sive actions to take, or provide other directions to eliminate or reduce the hazard (ANSI Z535.4-2002). scrap: metals, paper, plastic, glass, rubber, or textiles that are diverted, collected, sorted, shredded, sheared, baled, chipped, separated, sized, or otherwise processed for use in making new products. side loading: a nonvertical load applied to the vertical plane of the front.
stabilizer: extendable members attached to the mounting base to increase the stability ofthe railmounted handler, but that may not have the capability of relieving all of the weight from the tracks.
structural competence: the ability of the handler and its components to withstand the stresses imposed by the applied loads.
swing: rotation of the upper structure for movement of loads in a horizontal direction about the axis of rotation.
swing lock: a positive mechanism that prevents rotation of the upper structure. swing mechanism: the machinery involved in providing rotation of the upper-structure.
three points of support: features of an access system that permits a person to use two hands and one foot, or two feet and one hand while ascending, descending, or moving about on the handler.
travel: the movementofthe handler under its own power from one location to another.
upper-structure: the rotating frame structure of the han- dler and the operating machinery mounted thereon. wheel base: the distance between centers of front and rear axles. For a multiple-axle assembly, the axle center for wheel base measurement is taken as the midpoint of the assembly.ASME B30.25 pdf download.ASME B30.25-2007 pdf free download
