How come the grab arm doesn’t look that badly damaged but the bridge is totally destroyed ■■?My first thought as we’ll ttx, never driven or used a hiab before,it must be well anchored to the body or was that a really weak bridge??
unfortunately there are two ends to an hiab, one was bolted to the chassis, the other wasn’t anchored at all,that’s why it hit the bridge
Cheers green

Just to add to that…Hi-ab’s need to be mounted to truck chassis in a heavy-duty (beefy??) style in order for them to lift loads safely during their normal operation. As with any lifting equipment they are over engineered with a built-in safety factor. The rest, I guess is down to physics - the road speed of the truck, the point and angle of the impact. Basically…the Hi-ab beat the bridge hands down…by a knockout!!!
I just hope the driver is ok, luckily the footbridge was out of order too!
One of the pics in the HTV link, looks like the bed of the wagon is bent from the rear axle back. So that arm is likely to be higher now than it was when it struck.
What I don’t understand is how he has not noticed, the nearest place he could of tipped is spinks which is about half a mile away but he’d of ripped phone lines down on kelham street. If he’d tipped else where I’m sure car drivers would of been trying to get his attention on Balby road
