Increasing efficiency in marine port


A marine port had issues with ship/barge unloading operations. Coal is unloaded frequently at the port, and it takes four days to unload. The crane bucket is heavily used and the actuation cables wear/fail in 3 days. Unloading has to be stopped to change the bucket cables. This causes extra labor costs to ship moorage, delay in port, and repair cost to bucket.. The goal is to increase the life of the wire, reduce the operators’ workload and increase efficiency by eliminating the need to change the wire during unloading.

Coal bucket


The Chesterton 601 Chain Drive Pin & Bushing Lubricant and the Chesterton 715G Spraflex Gold were applied.  Due to the small pulley diameter and frequent flexing of the cable, the wire rope were failing internally due to wear and abrasion. The Chesterton 1,2 System was recommended by applying Chesterton 601 to lubricate and clean the internal wires and core, and then the Chesterton 715 Spraflex Gold to the outer wire rope surfaces. This is done prior to each ship unloading.
