Steel zip wires are low-tech and well adapted to forest and monsoon environments, but, for safety reasons, they need to be renewed regularly.
Our typical wire ropes are composed of 133 tiny wires arranged in 7 bigger strands. Daily use of metallic rollers slowly flattens the upper strand, and would eventually lead to rupture of the upper tiny wire if the zip line were not frequently changed.
The maintenance of the wire system leaves us with considerable quantities of excellent second-hand crane-class rope wires for which we find new uses. Building suspension bridges is, for instance, a good way to recycle our cables.
