Will I Need to Re-calibrate my Load Pin when I get it on Site?
Load pins are normally calibrated in half or full blocks in a traceable compression test machine. When a load pin is supplied as the sensing member of a shackle, we would normally calibrate the total shackle assembly in tension.
Here at LCM Systems, we try to match the loading conditions that would be experienced in service but it would be unrealistic to totally simulate the on-site structure for every load pin manufactured. It is for this reason that for optimum system accuracy, a calibration in the final assembly is recommended.
Thanks to our in-house design team, when our products aren't quite what a customer requires for their particular application, we are able to use our considerable expertise to customise a standard load cell.
This happened recently when a multi-national marine engineering company in Canada enquired about our TELSHACK-B load cell. They liked the principle of a wireless telemetry shackle, but wanted to measure ship docking tension on a winch and the load cell had to handled by one person. This was hard to achieve with a conventional shackle, when the measurement range is 85te. A more compact, lightweight solution was needed.
The result was the LCM3782 Wireless Telemetry Mooring Link Load Cell, that you can read about in full here.
