After setting a headwall for underground drainage.
The operator backed the crane away from the site in sugarsand with the boom straight up.
As the pictures show, the swing lock was not engaged.
The outrigger pad hung up on a 30′ long submersible pump lying on the ground, on the blind side of the crane (See Photo #4), causing the tires to spin in the soft ground, making the crane lean and without a swinglock, the crane rotated over the side.
The company originally called a towing company, who dispatched two C-class wreckers (one, a 70ton unit with a rotating boom) to upright the crane.
With the crane’s boom being straight up they couldn’t hook to it high enough.
Luckily we had a 100ton Liebherr staged at my house and righted the crane while the wreckers stabilized the carrier.
The operator was bruised up but Okay.
