Ignoramus11173 wrote: Scary situation. http://www.machinerymoverschicago.com/blog/Crane-Fail/ Wow! It's difficult to tell from the perspective in the picture, but it looks to me like the crane was set excessively far away from the lift point and had the boom at too shallow an angle, looking 45 degrees or so. A couple years ago I got to play with a 60T Grove moving 40' containers and we had it setup only about 40' from the crane boom pivot point to the lift point and the boom extended to give probably a 60 degree angle with loads of around 12,000# for a container and a small amount of contents. |

The crane looks new-ish, I would suppose that it could have a weight reading from the pressure on the hydraulic winch. They have load cells up the boom at the top pulley. They have a cable reel on the outside of the boom that reels out cable to that load cell. There is a computer in the operator's cab that give all the relevant information, load ratings based on boom angle, CG calculations, etc. A couple years ago I got to play with a 60T Grove moving 40' containers and we had it setup only about 40' from the crane boom pivot point to the lift point and the boom extended to give probably a 60 degree angle with loads of around 12,000# for a container and a small amount of contents.

I worked on German made Tower Cranes with horizontal booms, twenty years ago, that had a load limiting device on them. They wouldn't pick up a load that was too heavy for them and if you picked a load up close to the tower and tried to move it out the boom to a position where the load was too heavy for the crane the in/out function stopped any further outward movement. I was told by the crane operator that this feature was common on tower cranes. -- cheers, John D.Slocomb |

I recall seeing a photo of a tree removal gone bad. They were
cutting down a tree behind the house, and had a truck mounted crane reaching over the roof to the tree. When you saw it, the tree was still in the back yard but the trunk was facing the stars at say 130 degrees, with the boom having cut the house in half. -- A host is a host from coast to & no one will talk to a host that's close..........................
