Load Indicating Device - Electronic Shackle

1. A signed Certificate of Compliance is required which validates and states the electronic load indicating devices meet items 1.1 thru 1.13 below:

1.1. Specifications - Meet ASME B30.26 requirements, 26-1(Shackles) and 26-6 (load indicating devices).

1.2. Material Load Indicator: The load bearing elements of the load cell pin and bobbin have no cast iron parts. Precipitation hardened stainless steel (e.g., PH 17-4) load bearing elements are age hardened at a minimum temperature of 1025°F. The material composition and heat treatment of aluminum meet the requirements for ASTM B211. The material composition of steel load bearing elements are in accordance with the requirements of Federal Specification RR-C-271 or ASTM A564/A564M. Shackle Bales: are forged steel and meet the technical requirements of Federal Specification RR-C-271 for material composition (Grade A or B as applicable).

1.3. Hardness The steel load bearing elements have a hardness value of less than or equal to 40 HRC. (This does not apply to the shackle bale).

1.4. Surface Treatment Load Indicator: The load bearing parts of the load cell pin and bobbin which require non-destructive testing, are free of all types of surface treatments such as paint, galvanizing or plating.

Shackle Bales: Shackle bales have NO surface treatment such as paint, galvanization or other coatings. No RFID device installed. Exception: less than 0.002 inches of nickel plating is acceptable.

1.5. Minimum Factor of Safety The load bearing parts of the load cell pin have a minimum safety factor of 5:1 for steel and 7:1 for aluminum, based on the minimum ultimate strength. Shackle Bales: The shackle bales have a minimum safety factor of 5:1.

1.6. Accuracy The minimum accuracy of the load cell is +/-1% of applied load.

1.7. Calibration The load cell shackle is capable of being calibrated using standard industrial calibration equipment.

1.8. Remote Readout The remote readout is readable from a distance of 10 feet in both daylight and low light conditions. The display reads a minimum of five digits and calibrated for pounds.

1.9. Protection against Inadvertent Disassembly The load cell does not inadvertently disassemble due to rotation.

1.10. Battery Batteries for both the load cell and remote readout have a minimum use time of 20 hours.

1.11. Operating Frequency The load cell/readout is compliant with Part 15 of F.C.C. Rules and Regulations.

1.12. Marking

and safe working load limit to provide traceability of the item to the manufacturer.

1.13. General The load cell is capable of operation in an outdoor environment (temperature, humidity, rain) without causing damage or affecting the operation of the entire load indicating system. The load cell shall operate within 14 degrees Fahrenheit to 104 degree Fahrenheit.

A Data Report is required which provides the information in items 2.1 and 2.2 below:

2.1. Periodic Load Testing - The manufacturer shall either 1) provide authorization for periodic load testing between 150% and 155% of the manufacturer's rated capacity/working load limit or 2) provide the recommended maximum periodic test load, and provide a statement that the periodic load test as specified above will not damage, cause permanent deformation or affect the operation or warranty of the load cell.

2.2 Defect Removal The manufacturer shall

indicate in writing 1) the allowed amount of defect removal on the load pin and 2) authorization for defect removal by grinding on the shackle bale, provided that such reduction anywhere on the shackle bale does not reduce the cross-sectional diameter of the bow to less than 90% of the corresponding dimension (D or

P) shown in Fed. Spec. RR-C-271. Grinding shall longitudinally follow the contour of the shackle bale and be contoured with a 3:1 taper.

3. A signed Certificate of Test, Inspection and Calibration for each Electronic Load Indicating Devices (identified by a unique serial number) to document the following:

3.1. Static Load Test as an Assembly Load test the load cell

pin, bobbin and shackle bale (as an assembly) to 150% (-0,+5%) or an amount recommended by manufacturer. Hold the load test for a minimum of 10 minutes.

3.2. Visual Inspection ( - After the proof test, the manufacturer shall visually inspect the load indicating device assembly for damage such as nicks, gouges, cracks or other defects that could reduce the load bearing capacity.

3.3. Magnetic Particle (MT) or Liquid Penetrant (PT) Inspection (

- Following load tests, all accessible surfaces of the load pin, bobbin and shackle bale shall be (for steel) Magnetic Particle Inspected (MT) OR (for non-ferrous metal) Liquid Penetrant inspected (PT) per NAVSEA Technical Publication T9074-AS-GIB- 010/271, (TP-271), requirements for Non-Destructive Testing Methods.

Acceptance criteria shall be per MIL-STD-2035, latest revision. No indications greater than 1/16 inch are allowed.

3.4 Calibration - Calibrate the load cell to a

minimum +/-1% Accuracy.

4. Two sets of operating and instructions manuals are required which have detailed maintenance, operational, calibration, troubleshooting procedures, and detailed drawings showing complete construction of the electronic LID shackle

5. The Contractor shall extend to the Government the full coverage of any standard warranty normally offered in similar sale, provided such warranty is available at no additional cost to the Government

6. Failure to provide the Contract Data Requirements Lists (CDRLs) above shall be cause for rejection of this material.

7. Changes to specifications or technical requirements are NOT ALLOWED without Shipyard (Code 2370.21) approval via the Administrative Contracting Officer (ACO).
