Empirical solution is best. 2

Sometimes needless center of gravity calculations just waste time and hold up the progress of a job. The best course of action is to proceed with the project and make small corrections as necessary. Here is a good example...

The last one was photoshopped.

Oops, right you are! I've been had. The ninth image is the same as the fifth except for the phoney part. I guess I had better learn not to be so trusting. Duh.

You're not the first!

More relevant to this forum is the fact that the vertical load would have caused the wrecker to rotate around the outrigger foot, not slide sideways off the edge.

True, unless the retaining wall or embankment failed. 30 years ago I saw that happen to a modular house in Altamont, NY. It ruined the crane operator's whole day.

Just for the record - Do we believe the first part of the sequence? a saw the photos of the first crane about a year ago and just accepted them. The doctored last photo was not amongst them but I'm now thinking again.

The sequence of pictures reminded me of something that I witnessed in 1969 while seving in Vietnam.

First a jeep got stuck in the mud. A ton and a half truck came by and tried to pull the jeep out of the mud, but it became stuck. Next they sent a two and a half ton truck out, but it also got stuck in the mud. The following day a helicopter flying crane came by and pulled them all out. At the time we thought the whole episode was pretty funny.

It wasn't that difficult. Very poor photoshop fraud.

look at the last picture where the big crane was in the water too, look in the background at the red car on the pier it was there in the early pictures - look a the people too - then look at the second to
last picture - there is a van in front of the red car... also compare the first picture after the first crane was fully in the water -- compare the position of the people with the last picture of the second crane
in the water. Lastly, where did the foreground branches go?
