GENERAL NOTES:

1. PURPOSE

1.1. THIS DRAWING WAS PRODUCED TO SUPPORT A NEW DESIGN FOR AN 6 INCH BEAM CLAMP. OTHER DESIGNS WITH THE DESIRED CAPACITY ARE TOO LARGE TO RIG FROM IN CERTAIN AREAS. PAC-MAN STYLE BEAM CLAMPS

DO NOT HAVE THE DESIRED CAPACITY AND WILL BE DISCONTINUED.

2. MATERIAL

2.1. MATERIAL WILL BE 1-1/8 INCH THICK USING EITHER HY80 OR HY100 STEEL MIL-S-16216. (HY100 IS PREFERRED).

3. GENERAL

3.1. BREAK ALL SHARP EDGES AND REMOVE ALL BURRS.

3.2. DESIGNED AS A CATEGORY B SERVICE CLASS 0 - BELOW-THE-HOOK LIFTING DEVICE PER ASME BTH-1-2017 PER

NAVFAC P-307.

3.3. INITIATE MACHINING OF EACH PIECE ON THE OUTSIDE EDGE NEAR THE 1 INCH RADIUS.

3.4. ENSURE THE SUPPORTING STRUCTURE IS ADEQUATE FOR SUPPORTING THE BEAM CLAMP’S RATED LOAD AND LOADING CONDITIONS. CONTACT THE COGNIZANT ENGINEERING CODE REGARDING CAPACITY OF THE

SUPPORTING STRUCTURE.

4. INSPECTION CRITERIA (CODE 740 RIGGING LOFT)

4.1. CODE 740 RIGGING LOFT SHALL CERTIFY AND TAG BEAM CLAMPS PER IAW CLHM VOL. III CH. 2 (LATEST REVISION)

SECTION 5.2.1.

4.2. WLL IS 5000 LBS FOR AN ANGULAR LOADING RANGE FROM 0°-180° WITHIN THE PLANE OF THE EYE.

4.3. BEAM CLAMPS ARE INTENDED FOR A 15 YEAR SERVICE LIFE. DISCARD SET OF CLAMPS AT THE END OF THEIR SERVICE LIFE. THE SERVICE LIFE SHOULD BE NOTED WITHIN THE EQUIPMENT HISTORY FILE.

4.4. TRAM MARKS SHALL BE PLACED AT THE OPEN END OF THE BEAM CLAMP. REFER TO DRAWING SHEET 2 FOR APPROXIMATE LOCATION. REJECTION CRITERIA IS ±5% DISPLACEMENT FROM ORIGINAL MEASUREMENT.

5. CODE 740 RIGGERS

5.1. USE IN ACCORDANCE WITH CLHM V0L. III CH. 1 (LATEST REVISION) SECTION 6.1.8.2.1.

5.2. BEAM CLAMPS ARE DESIGNED AS A SET ONLY TO BE USED SIMULATNEOUSLY WITH A 7/8 INCH SHACKLE.

5.3. EACH SET OF BEAM CLAMPS ARE MADE UP OF BOTH ONE MALE AND ONE FEMALE PIECE.

5.4. REFER TO NOTE 3.4 REGARDING THE SUPPORTING STRUCTURE AND THE STRUCTURE’S CAPACITY.

5.5. BEAM CLAMPS ARE DESIGNED TO HAVE A HOLD-BACK IN PLACE WHEN SIDE-PULLING MORE THAN 5°

OUT OF PLANE. PLACE HOLDBACK IN BAIL OF THE SHACKLE ONLY.

5.6. THE 6 IN BEAM CLAMPS ARE DESIGNED FOR 6 IN WIDE FLANGE BEAMS. ENSURE THE BEAM CLAMPS DO NOT

HAVE THE ABILITY TO DISENGAGE FROM THE BEAM.

5.7. IT IS PROHIBITED TO USE ONLY HALF OF THE SET AT ANY GIVEN TIME, SUCH AS ONE SIDE ONLY HOOKED ONTO

AN OBJECT.

6. SURFACE PREPERATION AND PAINT

6.1. ALL EXPOSED STEEL SURFACES, SHALL BE ABRASIVE BLASTED TO A NEAR WHITE METAL CONDITION AS DESCRIBED IN THE SPECIFICATION FOR SSPC-SP-10. ALL GREASE, OIL, AND SURFACE DEBRIS SHALL BE REMOVED BY SOLVENT WIPING AND/OR DETERGENT/WATER SCRUBBING PRIOR TO ABRASIVE BLASTING.

PAINT SHALL BE APPLIED IMMEDIATELY AFTER SURFACE PREP.

6.2. APPLY AN ENAMAL CORROSION MITIGATING PAINT SYSTEM BEST SUITED BY THE PAINTERS PREFERENCE.

6.3. COLOR OF PAINT SHALL BE SAFETY YELLOW (OR SIMILAR).

7. CONTACT CODE 715 RIGGING ENGINEERING REGARDING ANY QUESTIONS OR CONCERNS. (360)476-2919
