Factory Acceptance Checks for a Wheel Loader: Turning Specs Into Pass/Fail Tests
A buyer's guide to defining practical pass/fail checks for a wheel loader factory acceptance test, using catalog reference values as starting points for RFQ and demonstration questions.
Before signing off a wheel loader, decide which checks must produce a clear pass or fail rather than a subjective impression. Start with the working envelope: does the machine, configured as offered, meet the reference values of 3.5 m³ bucket capacity and 5,000 kg rated load, and can the supplier show how those figures were derived for the intended soil and aggregate duties?
For a factory acceptance test, ask for measurable checks on hydraulic cycle times, lift and dump function, steering response, braking, and instrument warnings. Define acceptance limits in advance and record them in the RFQ. Ask whether the 162 kW at 2,000 rpm gross power figure is measured to a stated method, and request the corresponding test report. Confirm the 17,950 kg operating weight with the bucket and attachments specified, since configuration changes the number.
Build a demonstration checklist: cold start, full-bucket loading, repeated lift cycles, and a leak inspection after operation. Each item should have a pass criterion agreed in writing, not a verbal opinion.
Before requesting a quote, confirm with the supplier which tests are performed at the factory, what documentation is supplied, who witnesses the test, and how deviations are resolved.
