With the requirements for higher crushing rates and reduced operating costs there appeared to be an opportunity to permanently link cane bins together in pairs, where haul-out and tipping operations are performed in two bin modules. A new coupling link has been developed to permanently couple a bin pair together. This coupling link can eliminate single bin pushes into the tippler, and reduce stops in the feeding station associated with uncoupling complications from Willison couplings. Both these items have significant flow-on effects for factory operations. An additional benefit of the coupling link is to halve the maintenance cost associated with an automatic cane bin coupling pair. This coupling link was designed with sufficient flexibility to enable use in roll-on roll-off applications. Field tests have been conducted from 1999 to validate the performance of the coupling link from an operations and maintenance perspective. Comparative compression tests of a rake of cane bins with conventional Willison couplings and coupling links have demonstrated that a rake of cane bins with coupling links is less prone to derailment.
