The Strainstall towing load monitoring system is designed to give towing vessel masters a direct reading of tension in a towing hawser. It consists of load cells or a load measuring pin fitted to the towing hook, quick release mooring hook or winch, plus a readout/alarm warning unit which can be set with overload thresholds to suit the gauge of rope or wire being used for the towing operation.
There are 3 typical towing load monitoring configurations:
- A single channel system with the load pin designed for incorporation into a swivel joint of a tugboat quick release mooring hook
- For double drum winches, with both outputs leading to a single display unit with a switch to select the desired measurement channel
- For marine towing winches, with the load being measured by load cells in the brakestay or under the bed of the winch.
Key features of towing load monitoring include simple installation, full environmental sealing, accurate readings, easy maintenance and optional additional readouts.
