Dear Sir, Attached is a photo of a Grove TM 800 trying to lift around corners. Located At Bunbury Western Australia the crane was attempting to lift a stuck hatch cover and it gave way swinging out of radius the ship stopped the crane tipping over. I like your site and include the photo and I have several others to include as part of your site. Michael This accident occurred in Canada in 1998. The contractor needed a 100 ton capacity crane to place some girders that were 70 feet long and weighed 18 tons. For whatever reason, they used a 50 ton picker instead. Wind came into play and caused the crane to tip. See the results in the photos. Unfortunately, three iron workers were injured in the accident. In this accident the operator was attempting to walk down to the bulkhead down the hill in the photo. At this time the exact cause of the incident is still unknown. Mainly because I have walked cranes down grades steeper than this I feel it was a mechanical failure of some sort, or just plain operator error. A crawler w/travel engaged in forward while backing down a steep grade will not just take off (should it take off faster than expected you simply gag it) while you may burn out the clutches you won't lose the crane. In the photo 9310-3900 you will see I have highlighted another crane on the hill. Less than 30 min. after this photo was taken the crane(3900) rolled down the hill toward the bulk head. I should have those PICS scanned in to send by 7/27/99. The 3900 lost it's boom as well. The 3900 accident was purely operator error. The operator was not the normal operator for that crane and inadvertently engaged the travel in the wrong direction. In his case he was doing the right thing but in the wrong direction. when he "gagged it to slow it down he effectively drove it off the hill." I don't know how familiar you are with cranes, so I will add EVERY crane operates differently so the danger inherent in casually swapping operators is obvious. The opinions I have stated here are just that opinions. From my experience working, in, around, and with cranes it is what I feel happened. Investigations are still pending.

(shown above) Photo #1 Photo #2 Photo #3 May 1995 photo shows RT crane that was being transported from Bombay, India to a nearby job-site. Crane was loaded onto a highboy trailer by a local transportation contractor. The contractor did not have the experience or equipment for hauling such a load. The trailer ran over the small mound of gravel in the road and subsequently tipped over. No one was injured in the accident. The crane was recovered, there was some boom damage, but it was repaired and subsequently placed back in service. |
