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 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.
(a) The hook material shall have sufficient ductility to permanently deform before losing the ability to sup- port the load at the temperatures at which the specific hook will be used. (b) When a latch is provided, it shall be designed to retain such items as, but not limited to, slings and chains under slack conditions. The latch is not intended to support the load. (c) Attachments, such as handles, latch supports, etc., shall not be welded to a finished hook in field applica- tions. If welding of an attachment such as these is required, itshall be done inmanufacturing orfabrication prior to any required final heat treatment.
