Functional Testing
Systematic verification that every control, interlock and safety system operates and intervenes exactly as designed.
Functional testing verifies that a machine's controls, interlocks and safety systems all work as the designer intended. It is easy to assume that because a machine moves, its safety systems are sound, but overload cut-outs, tilt alarms, emergency lowering and interlocks only earn trust when they are deliberately exercised. We functionally test EWPs and cranes to confirm each protective function activates at the right point and behaves predictably.
What functional testing covers
Our engineers operate every control and provoke every protective function in a controlled way: overload sensing, tilt and stability cut-outs, emergency lowering, interlocks, limit switches and audible and visual alarms. The aim is to confirm not just that a function exists, but that it intervenes at the correct threshold and returns the machine to a safe state.
Functional testing frequently accompanies load testing, so that both the machine's capacity and its safety responses are verified together.
- Verification of overload and stability cut-outs
- Testing of emergency lowering and stop functions
- Check of interlocks, limit switches and alarms
- Confirmation of correct intervention thresholds
Where it fits
Functional testing is part of annual and major inspections, follows repairs to control systems, and accompanies load testing. It is often the check that distinguishes a machine that looks compliant from one that will actually protect its operator in an emergency.
Reporting
Each function is recorded as tested and its behaviour documented, with any fault clearly identified for rectification before return to service.
