ABSTRACT:
A spring rewound tagline device having an elongated housing on which a cable reel is rotatably mounted by a shaft journalled in a bearing fixed to the housing. The shaft rotates a core structure which in turn tightens a coiled spring arranged around the core structure by winding the coils relative to the bearing. One end of the spring is connected with the core structure by an anchor means, and the other end of the spring is connected with a fixed structure by an anchor means in the form of a frangible shear pin which will break and release this end of the spring, when a predetermined excessive load is placed on the spring, thus preventing damage to the spring as a result of the excessive load.
