2、 York, N. Y. 1001 7 Date of Issuance: January 31, 1986 This Standard will be revised when the Society approves the issuance of a new edition. There will be no addenda or written interpretations of the requirements of this Standard issued to this Edition. This code or standard was developed under pro

3、cedures accredited as meeting the criteria for American National Standards. The Consensus Committee that approved the code or standard was balanced to assure that individuals from competent and concerned interests have had an oppor- tunity to participate. The proposed code or standard was made avail

4、able for public review and comment which provides an opportunity for additional public input from industry, academia, reg- ulatory agencies, and the public-at-large.

10、tional Standards Institute, Inc. (ANSI), with the Society of Automotive Engineers and The American Society of Me- chanical Engineers as joint sponsors. Subcommittee No. 15 was appointed in March of 1960 and asked to give initial consider- ation to the establishment of a standard on forged eyebolts,

11、including rated capacity. At its first meeting held on April 22, 1960, the committee decided to ask all of the leading suppliers to furnish dimensions, tolerances, and rated capacity for their standard eyebolts. These data were collected, consolidated, and studied in detail. It was soon apparent tha

12、t it would be impossible to develop an ANSI standard which would agree with even a small percentage of the standard products then being produced. The first proposal, therefore, attempted to come as close as possible to an average value and still maintain an orderly progression from the smaller to th

13、e larger sizes. ANSI Standards Committee B18 approved the proposal by letter ballot taken on September 24, 1964, and following approval by the sponsors it was submitted on July 28, 1965, to ANSI for approval. Because of a conflict with USA Standard Specification for Carbon Steel Eyebolts, (338.2-196

14、4, final approval was withheld. Subsequent to the withdrawal of G38.2-1964, ANSI approved the B18 proposal on February 18, 1969. This revision was approved by letter ballot of ASME Committee B18 on August 27, 1982, and was subsequently approved by ASME (the sponsor) and submitted to ANSI for designa

15、tion as an American National Standard. ANSI approval of this Standard was granted on July 17, 1985. 111 .

19、from visible defects that might affect serviceability. Eyebolts should be routinely vi- sually inspected for such defects as: (a) bent or distorted eye or shank (b) nicks and gouges (c) obvious wear (d) worn and/or distorted threads (e) cracks If any of these defects are visible, the eyebolt should

20、be removed from service and destroyed. 10 APPLICATION (a) Capacities shown in Tables 3 and 4 are for car- bon steel ASTM A 489 eyebolts, at temperatures be- tween 30F (-1C) and 275F (135C). Carbon steel is subject to failure from shock loading at temperatures below 30F (- 1 “C) and loses strength at

21、 temperatures above 275F (135C). (b) Refer to Tables 3 and 4 for reduced loads on an- gular lift capacities. (c) Loads must always be applied to eyebolts in the plane of the eye, not at some angle to this plane. (See Fig. 1.) (d) Type 1 plain eyebolts must be engaged to within one-half turn from the

22、 eye end of the threads to obtain rated capacities. (e) Type 2 shoulder eyebolts should bear firmly against the mating part; otherwise the rated capacity must be reduced to those indicated for Type 1 eyebolts. A steel washer or spacer not to exceed one thread pitch may be required to put the plane o

23、f the eye in the direc- tion of the load when the shoulder is seated. (f) To attain the rated capacities in Tables 3 and 4, minimum thread shank length of engagement must be as follows: Steel - one thread diameter Cast iron, brass, bronze - 1.5 thread diameter Aluminum, magnesium, zinc, plastic - tw

24、o thread (g) Eyebolts should be visually inspected for flaws prior to applying a coating. Such coating as painting, galvanizing, or plating covers flaws and interferes with inspection. Coatings are not recommended. (h) Tapped holes for plain pattern (straight shank) eyebolts are threaded for the ful

25、l length of eyebolt en- gagement Tapped holes for shoulder pattern eyebolts are threaded for the full length with clearance for the un- threaded portion of the eyebolt to allow shoulder seat- ing.

A1 INTRODUCTION Two methods are currently used in specify

49、ing the ca- pacities of forged steel eyebolts. One is more commonly used by riggers and shop personnel, while the other is generally preferred by engineers and designers of lifting rigs. Care must be exercised in selecting and using the correct type of capacity for each application. A2 RIGGERS CAPACITY The riggers capacity refers to the actual load a single eyebolt can lift. The allowable load varies with the an- gle between the leg of the lifting rig and the shank of the eyebolt. In general, it also assumes tha
