Lessons Learned – Mobile Crane/Preventive Maintenance
Year: 1997
Abstract: Description of Driving Event:
The mobile crane was holding a 20 foot section of 36" diameter pipe while a section of handrail was being removed. Removal of the handrail was necessary in order to remove the section of pipe. While the crane was in operation, one of the crane's outriggers "leaked down", and caused a brief uncontrolled movement of the pipe. No damage occurred to the equipment, and property surrounding the crane. Most importantly, there were no injuries to personnel. The crane was not equipped with a "Positive Mechanical Block (PIN)" system. Subsequently, it was found that the crane had not been proof load tested for over a year.
