ASME B30.25:2013 pdf download.Scrap and Material Handlers
Volume B30.25 includes provisions that apply to the construction, installation, operation, inspection, and maintenance of scrap and material handlers consisting of a base, a revolving upper structure with operator’s station(s), and a front for lifting scrap or materials using attachments such as magnets and grapples, and any variations thereof in which the equipment retains the same fundamental characteristics. The provisions included in this volume apply to scrap and material handlers that are crawler mounted, rail mounted, wheel mounted, or on pedestal bases. The scope includes hydraulically operated scrap and material handlers powered by internal combustion engines or electric motors to lift, lower, and swing scrap and material at various radii. Hydraulic excavators designed for digging and trenching, forestry machines, machines designed for demolition, lattice and telescopic boom cranes, rail- mounted cranes for railway and automobile wreckclear- ance, and equipment covered by other volumes of this Standard are excluded.
A scrap and material handler is herein after referred to as a “handler.” Handlers may be mounted on one of the following bases: crawler handler: mounted on a base, equipped with crawler tracks for travel (see Fig. 25-0.2.1-1). pedestal-mounted handler: mounted on a pedestal base (see Fig. 25-0.2.1-2). rail-mounted handler: mounted on a base, equipped for travel on a railroad track (see Fig. 25-0.2.1-3). wheel-mounted handler (multiple control stations): mounted on a base, equipped with axles and rubber-tired wheels for travel, a power source(s), and havingseparate control stations for driving and operating (see Fig. 25-0.2.1-4). wheel-mounted handler (single control station): mounted on a base, equipped with axles and rubber-tired wheels for travel, a power source, and having a single control sta- tion for driving and operating (see Fig. 25-0.2.1-5).
accessory: a secondary part or assembly of parts that contributes to the overall function and usefulness of a machine. administrative or regulatory authority: a governmental agency, or the employer in the absence of governmental jurisdiction. ancillary equipment: equipment not required for the basic operation of the handler. arm (stick): the second section of a front, one end of which is attached to the boom. arm cylinder(s): the hydraulic cylinder(s) that moves the arm in relation to the boom. assembler/modifier: entity thatassembles and/or modifies basic components to produce a handler. attachment: an accessory like a magnet or grapple that is affixed to the second or third member of a front. axis ofrotation: the vertical axis around which the handler upper-structure rotates. axle: the shaft or spindle with which or about which a wheel rotates. On wheel-mounted handlers it refers to a type of axle assembly including housings, gearing, differential, bearings, and mounting appurtenances. axle (bogie): two or more axles mounted in tandem in a frame so as to divide the load between the axles and permit vertical oscillation of the wheels. backward stability: the handler’s ability to resist overturn- ing in the direction opposite the front while in the unloaded condition.ballast: weight used to supplement the weight of the handler in providing stability for handling loads (the term “ballast” is normally associated with rail-mounted 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. front: consists of two or three structural members actu- ated by hydraulic cylinders that are affixed to the upper- structure for mounting the attachment (see Figs. 25-0.2.2-1 and 25-0.2.2-2). 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.
