Boom too High
A truck transporting a boom lift earlier today caused a major traffic snarl up after the boom struck an overpass and came off of the truck’s trailer.
The incident happened in Brisbane, Australia at Kangaroo Point. The overpass was damaged but there were no injuries and no damage to any other vehicles.

The boom lift was just high enough to catch the bridge
The lift, a JLG Ultra boom, was being transported with the boom slightly elevated in the jib tuck-under position which reduces the overall length of the machine but can increase the overall height …..Just enough to catch the overpass.
Note:
Unlike many smaller boom lifts where the the jib tuck-under position causes an increase in overall height, the JLG ultra booms will stow in this position without increasing their 3.05 metre overall height.
If The boom had been stowed corrcetly this may not have happened. JLG Ultra Booms swing the jib under the boom for transport?? As stated in Operators manual
