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 hi 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.
SECTION 10-0.2: DEFINITIONS
abnormal operating conditions: eiwironmental conditions that are unfavorable, harmful, or detrimental to or for the use of a hook.
administrative or regu1atori authority: governmental agency or the employer in the absence of governmental jurisdiction.
appoin ted: 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 employer or the employer’s representative as being cornpetent 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).
This Chapter applies to all hooks specifically shown in Figs. 17 through 21 that do not support a load in a direct-pull configuration, such as grab hooks, foundry hooks, sorting hooks, and choker hooks.
SECTION 10-2.1: MARKINGS AND CONSTRUCTION
10-2.1.1 Markings
Manufacturer’s identification shall be forged, cast, or die stamped on a low stress and nonwearing area of the hook.
10-2.1.2 Construction
(a) The hook material shall have sufficient ductility to permanently deform before losing the ability to support the load at the temperatures at which the specific hook will be used.
(b) Rated loads for a hook, when used in the manner for which it is intended, shall be equal to or exceed the rated load of the chain, wire rope, or other suspension members to which it is attached. In those instances when this is not feasible, special precautions shall be taken to ensure that the rated load limit of the hook is not exceeded.
SECTION 10-2.2: INSPECTION, TESTING, AND MAI NTENANCE
10-2.2.1 Inspection
10-2.2.1.1 Inspection Classification
(a) Initial Inspect ion. Prior to initial use, all new and repaired hooks shall be inspected to verify compliance with the applicable provisions of this Volume.
(1) Inspection procedure and record keeping requirements for hooks in regular service shall be governed by the kind of equipment in which they are used. When such requirements for hooks are stated in standards for the specific equipment, they shall take precedence over the following. Otherwise, there shall be two general classifications based upon intervals at which examination shall be performed. The classifications are herein designated frequent and periodic, with intervals between examinations defined as follows:
(1) Frequent inspection. Visual examinations by the operator or other designated person with records not required:
(a) normal service — monthly
(2) Periodic lnspection. Visual inspections by a desig-nated person making records of apparent external condi-tions to provide the basis for continuing evaluation
(a) normal service – yearly, with equipment inplace
(b) heavy service – semiannually,with equip-ment in place unless external conditions indicate thatdisassembly should be done to permit detailedinspection
(c) severe service—quarterly, as in heavy service[see para. 10-2.2.1.1(b)(2)(b)],except that the detailedinspection may show the need for a nondestructive typeof testing
10-2.2.1.2 Frequent Inspection
(a) Frequent inspection shall include observationsduring operation.
(b) A designated person shall determine whether con-ditions found during the inspection constitute a hazardand whether a more detailed inspection is required.(c)Hooks shall be inspected for the following items:
(1) distortion, such as bending, twisting, orincreased throat opening
(2) wear
(3) cracks, nicks, or gouges [see para.10-2.2.3(b)](4) hook attachment and securing means
10-2.2.1.3 Periodic lnspection
(a) Inspection of hooks shall be performed as definedin para. 10-2.2.1.1(b)(2).
(b)The inspection shall include the requirements ofpara.10-2.2.1.2.
(c)Hooks having any of the following conditions shallbe removed from service until repaired or replaced.
