Failure cause, frequency, and repair for forest harvesting equipment
Objectives of the study were to determine the frequency and cause of failure for selected pieces of forestry equipment, and the time to repair those failures. Time between failure and time to repair distributions are presented for 3 groups of forest harvesting machines, comprising 12 rubber-tyred feller bunchers, 4 rubber-tyred grapple skidders, and 3 mobile chippers. Although only aggregate models were calculated, considerable variability in times between failures occured within each type of machine, significant differences being found between machines in each group. These differences indicate that a machine's availability is heavily dependent on its working environment, the operator, and maintenance practices. Reasons for failures are tabulated for each group.
