Three Service Layers Equipment Managers Actually Buy
Hydraulic flow tests, undercarriage tension and boom-pin clearance gauges — not vague “full-service packages.”
Pre-delivery Commissioning
Hydraulic flow test, slew-bearing torque audit and pilot-pressure baseline are logged before the crane or excavator leaves the yard. Anti-two-block sensors and outrigger pad kits are verified against the signed ASME B30 lift plan so the first pick is not a discovery exercise.
Scheduled Field PM
Undercarriage tension, Tier 4 Final emissions audit, boom pin and bushing rotation run on a 250 / 500 / 1000 hour cadence. ISO 4406 return-line samples flag pump wear before hoist speed (m/min) drifts outside the load chart.
Major Overhaul & Rebuild
Cylinder reseal, final-drive swap and cab vibration calibration at roughly 8,000 hours restore residual value above wholesale book while the machine reactivates on the same pad where it last worked.
