Summary
This flash summarises two crane boom failures involving ineffective upper hoist limits. One involved a missing pneumatic valve blanking plug and a hydraulic pump actuator fault; the other involved a defeated operational limit and incorrectly set ultimate limit. It recommends robust inspection and functional testing against manufacturers’ specified boom angles.
