THE CLAMPING FUNCTION

Automatic mooring with tension reg.

Chain sizes from 76 to 166 mm diameter will be held and controlled against accidental rotation when the tension is slackened off. No insert is required for holding chain

Purpose 1

To assist in moving tugger wires to come within the grasping range of the shark jaw, eliminating the need for personnel to enter exposed deck. It can also move large chain and wire under low tension.

 
Purpose 2

To hold and control chain and wire from dangerous spinning when slackened off after mooring line is disconnected from the shark jaw.

Remote control

Operation of towing pins, centring device and shark jaw is remote controlled from the bridge reducing risk to deck crew by avoiding work on unsecured heavily loaded chains or wires. A portable remote control is available for use during service and maintenance work.
