October 09 Approximately 2 years ago our company embarked on a machine upgrade program to take advantage of new opportunities in the logging industry in Western Australia. We purchased 4 machines with feller buncher heads and 6 skidders. These machines are a change from our previous cut to length operations. Due to the higher hydraulic pressures the new machines are running we have had high failure rates on the standard swivels that came with the machines. We have tried different brands of swivels including a locally made product, as well as modifying the swivels with an engineer who assists us in a lot of machining and fabrication work. All attempts at achieving a swivel to last more than 300 hours in a high pressure environment has failed. These swivels have solved a problem that had been plaguing us since taking delivery of the new machines. We are now in the process of purchasing more of the swivels to replace the remaining ones still in operation. |
