Factory Acceptance Checks for a Mini Crawler Excavator
Buyers can turn an FAT for a 5.1 t mini crawler excavator into pass or fail checks covering hydraulics, controls, and earthmoving performance in soil.
For a 5.1 t mini crawler excavator ordered for earthmoving in soil, decide before the factory acceptance test which functions must pass without adjustment and which may be corrected and retested. That choice shapes the test script and the acceptance record.
Ask the supplier to demonstrate every hydraulic function through its full range, with the 0.15 m³ bucket fitted, and to state the pass criterion for each: smooth movement, no external leakage, and no abnormal noise. For the 35.5 kW engine, agree on how starting, idle, and working-speed response will be observed and recorded. Confirm whether a timed digging cycle in soil is part of the test, and if so, define the bucket load, cycle count, and what counts as a failed cycle.
Include track travel and steering in both directions, plus a check that the machine holds position on a slope the supplier confirms is within its stated limits. Record instrument readings and any fault codes at the end of the run.
Before requesting a quote, confirm with the supplier which checks it performs as standard, what test soil and bucket are used, who witnesses and signs the report, and how a failed item is corrected and retested.
