Worker Hurt in Crane Collapse

SUNBURY – A worker was hurt when a crane he was working on collapsed in Northumberland County.

 

A contractor was fixing a sign at CVS on South Fourth Street in Sunbury around 10 a.m. when the crane he was working on collapsed, and he fell off, according to the Sunbury fire chief.

 

The name of the worker and his condition were not released. The fire chief said his injuries were not life-threatening.

 

Around 50 to 100 gallons of hydraulic fluid spilled from the truck.

 

The CVS store remained open.

What's odd is, that looks like a 16' Werner scaffold plank resting on top of the ladder extension

I cant explain the ladder plank but it looks like the blocks under the frame holding the turret to the frame came off. you can see the bolts are still attached to the turret plate.  Thats scary

I havent had to deal with cranes in 15-20 years but I thought that aerial  equip had to be inspected by a 3rd party.  Either poor install. improper bolt sizing or severe rust.  All preventable.

This is a Wilkie Ladder truck.   The scaffold had nothing to do with the accident.  

The scaffold just provided a smooth surface to work from.

 

The most likely reason here is that the hardware failed under the chassis.   Weather conditions , snow, rain and road salt rusted

away the nuts and bolts here.  The New Road Brind Liquid used on the roads today is a death sentence to all steel and aluminum on the trucks.

It eats right thru everything. Anything over 8 years old is destroyed.

Cleaning this crap off immediately will help preserve your truck. General power washing everything else off is good practice

 

 

You should be inspecting all your equipment every 3 months for any signs of rust or fatigue.  

AND yearly Inspections by a Certified Aerial Co.

Assuming they were the right bolts to begin with, torqued down to the proper specs.  $$$$  As far as 3rd party inspections go it's hard enough to find anyone to service this equipment let alone inspect it.  Sign companies  repair when it breaks and expect the driver to be the inspector or "fall guy".  Most of the time the driver is barely a sign guy to qualify as aerial equipment inspector.   The equipment may also have been used past it's limits many times to weaken the bolts as in extended all the way out at almost a horizontal angle.  It happened to a 100ft Manitex bucket that was nearly all the way out installing a sign 20 ft off the ground. Can you say pop the bolts like popcorn.
