Annual Aerial Device Inspection

 

Annual Aerial Device Inspection

 

After a boom failure(sheared all but three rotation bearing bolts) of one of our 95' buckets this year we are contemplating implementing Magnetic Particle test & Ultrasonic Inspection during our annual Dielectric test & inspection. Does anyone else use these test annually or on a regular basis. Also, has anyone ever used American Test Center for outsourced inspections & test? Please help. Thanks!

"This is used in several Canadian provinces on boom lifts and forklifts. Some of the provinces mandate a mag test every year while other provinces leave it up to the construction site or mine. In the past 4 years, we have had thousands of mag particle tests completed on our equipment and I can only remember 1 time where they found a twist in a boom section (we should have found it ourselves during a visual inspection)."

We had a simular issue however we sheared all of the rotation bearing bolts. Since that time we have our testing facility check bolt torque annually and acoustic test every five years (we do not ultrasonic or magnetic test). As for the 95' truck, you may want to check the overcenter protection valve, that was the issue with our truck, becuase the boom will lurch when stowing and put additional strain on the rotation bolts. Please contact me if you woul like to discuss our findings.

We use American Test Center for all our testing needs and they have been great! They are very thorough and give detailed reports. We have been using them for about 10 years.

"Bolt torque should be performed on all annual inspections. When was the last annual inspection performed? And was the torque checked? Should be documented"

We do not use the particle or mag check however we check all booms twice a year and check torque to 80% of the manufactures recommended so we do not continually stretch the bolts. Then a torque seal is applied so it could be visually spotted during normal maintenance. We call 1 of the inspections a major were we go over everything and 1 a minor to check critical points (rotation bolts, bearings and any elbows or lift points.
