GENERAL NOTES:

1. PURPOSE

1.1. THIS DRAWING WAS PRODUCED TO SUPPORT A NEW DESIGN

FOR BEAM CLAMPS. OTHER DESIGNS HAVE CAPACITY BUT ARE

TOO LARGE FOR AN AREA, AND THE CURRENTLY USED PAC-

MAN STYLE BEAM CLAMPS DO NOT HAVE ENOUGH CAPACITY.

2. MATERIAL

2.1. MATERIAL WILL BE 1 INCH THICK PLATE 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. BEGIN CUTTING THE BEAM CLAMP SHAPE NEAR THE OUTSIDE

CORNERS AS SHOWN IN SHEET 3 AND 4.

3.4. ENSURE THAT THE SUPPORTING STRUCTURE IS ADEQUATE

FOR LOAD AND LOAD HANDLING. 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 IAW CLHM VOL. III CH. 2 (LATEST REVISION) SECTION

5.2.1.

4.2. WLL IS 5000 LBS WITH A 15 YEAR SERVICE LIFE. DISCARD

AFTER THE SERVICE LIFE. THE SERVICE LIFE SHOULD BE

NOTED WITHIN THE EQUIPMENT HISTORY FILE.

5. TRAM MARKS SHOULD BE PLACED AT THE END OF THE BEAM

CLAMP. REFER TO DRAWING FOR LOCATION. REJECTION CRITERIA

IS ± 5% DISPLACEMENT.

CODE 740 RIGGERS

5.1. REFER TO NOTE 3.4 REGARDING SUPPORTING STRUCTURE

AND CAPACITY.

5.2. USE TIEBACKS WHEN LOADING MORE THAN 5° OUT OF PLANE.

5.3. THE 4IN BEAM CLAMPS ARE DESIGNED FOR 4IN WIDE FLANGE

BEAM, ENSURE THE BEAM CLAMP WILL NOT HAVE THE ABILITY

TO DISENGAGE FROM THE BEAM.

5.4. THE BEAM CLAMPS SHALL ONLY BE USED AS AN ASSEMBLY

ONTO BEAMS; IT IS PROHIBITED TO USE 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.

6.2. APPLY AN ENAMAL CORROSION MITIGATING PAINT SYSTEM

BEST SUITED BY THE PAINTERS PREFERENCE.

6.3. THE COLOR SHALL BE SAFETY YELLOW (OR SIMILAR).

7. CONTACT CODE 715 RIGGING ENGINEER REGARDING ANY

QUESTIONS OR CONCERNS. (360)476-2919
