ASME B30.10:2005 pdf free download – Hooks
Within the general scope defined in Section I, ASME B30.10 applies to all types of hooks shown in Figs. 1 through 21 used in conjunction with equipment described in other volumes of the B30 Standard. Hooks supporting a load in a direct-pull configuration, with the load carried in the base (bowl/saddle or pin hole — see Figs. 3 and 4) of the hook, are covered in Chapter 10-1. Hooks that do not support a load in a direct-pull configuration are covered in Chapter 10-2.
abnormal operating conditions: environmental conditions that are unfavorable, harmful, or detrimental to or for the use of a hook. administrative or regulatory authority: governmental agency or the employer in the absence of governmental jurisdiction. appointed: assigned specific responsibilities by the employer or the employer’s representative. crack: a crevice-type discontinuity in the material. designated person: a person selected or assigned by the employerorthe employer’s representative as beingcom- petent to perform specific duties. hook, self-closing: a hook with a throat opening that is closed by a spring-loaded latch, gate, or bail that is manually opened for loading and closes upon release. It may be locked in the closed position (see Figs. 8 through 14). hook, self-locking: a hook with a throat opening that will close and lock when a load is applied, and will not open 1 until unloaded and the lock released (see Figs. 6 and 7). latch: a mechanical device used to close the throat open- ing of a hook (see Figs. 1 through 5). load: the total weight imposed on the hook. load, proof: the specific load applied in performance of the proof test.
load, rated: the maximum allowable working load. mouse: rope or wire used to close the throat opening of a hook. nick or gouge: sharp notch in hook surface which may act as stress riser in the area of the notch. qualified person: a person who, by possession of a recog- nized degree in an applicable field or certificate of pro- fessional standing, or who by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve problems relating to the subject mat- ter and work. service, heavy: service that involves operating at 85% to 100% of rated load as a regular specified pro- cedure. service, normal: service that involves operating at less than 85% of rated load except for isolated instances. service, severe: heavy service coupled with abnormal operating conditions. test, nondestructive: a test that does not destroy the func- tional use of the hook, such as but not limited to dye penetrant test, magnetic particle test, radiography test, and ultrasonic test. test, proof: a nondestructive load test made to verify the manufacturing integrity of the hook.
