ONA Marine have load cells designed into 10Te Crosby shackles for mooring installation activities. These load cells are particularly useful when continuous monitoring is required with digital readouts available on mobile phones.  The units are factory calibrated and read loads of 0 to 30Te. They are particularly useful for calibrating anchor handler main and tugger winches to mitigate accidental or in adverted overloading. ONA Marine have 4 such units for hire and available immediately.
