SECTiON 10-0.1: SCOPE OF ASME 830.10
Within the general scope defined in Section 1, ASME B30.1O applies to all types of hooks shown in Figs. I through 21 used in conjunction with equipment described in other volumes of the 1530 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.
SECTION 10-0.2: DEFINITIONS
al’normal 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 employer or the employer’s representative as being competent 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 MAINTENANCE
10-2.2.1 Inspection
10-2.2.1.1 Inspection Classification
(a) Initial Inspection. Prior to initial use, all new and repaired hooks shall be inspected to verify compliance with the applicable provisions of this Volume
(b) 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
(b) heavy service — weekly to monthly (c) severe service — daily to weekly
(2) Periodic Insp(vtton. Visual inspections by a designated person making records of apparent external conditions to provide the basis for continuing evaluation
(a) normal service — yearly, with equipment in place
(b) heavy service — semiannually, with equipment in place unless external conditions indicate that disassembly should be done to permit detailed inspection
(c) severe service — quarterly, as in heavy service Isee para. lO-2.2.1.1(b)(2)(b)J, except that the detailed inspection may show the need for a nondestructive type of testing
10-2.2.1.2 Frequent Inspection
(a) Frequent inspection shall include observations during operation.
Ui) A designated person shall determine whether conditions found during the inspection constitute a hatrd and whether a more detailed inspection is required.
(C) Hooks shall be inspected for the following items:
(1) distortion, such as bending, twisting, or increased throat opening
(2) wear
(3) cracks, nicks, or gouges Isee para. 1O-2.2.3(b)
(4) hook attachment and securing means
10-2.2.1.3 PerIodic Inspection
(a) Inspection of hooks shall be performed as defined in para. 1O-221.i(b)(2).
