An effective self-releasing choker hook should improve productivity and safety by reducing both the time to unhook in the landing and the chaser's exposure to hazard. FERIC has developed a modification to the conventional hook configuration and patented a simple, mechanical, self-releasing choker hook for cable yarding. Choker release is activated by the changing direction of pull that occurs when the operator lands the turn and begins to send the rigging back into the cutblock. Field evaluations on cable yarding operations in British Columbia, Washington State and Norway have demonstrated productivity increases exceeding 10%.
