‘Independent Stevedoring Ltd ‘operate at the ‘Port of Tauranga’ loading and unloading cargo from the busy container ships. Part of this work is to load logs onto the ships with a wire rope and spreader system. Some of the ropes are left around the cargo to allow easier removal when they reach their final destination. The ropes and twitches are then shipped back as deck cargo to NZ and rust during transit.Wire ropes rust on the inner strands and twitches also freeze solid because of the rust and have to be thrown away.
