Called by the Pennsylvania State Police Avondale Barracks to respond to Glen Run Rd and Old Limestone Road in
Highland Township for a tractor trailer loaded with 43,000 pounds of fertilizer that had struck a bridge and now had a
With the information we were given, we immediately dispatched a recovery supervisor, one of our heavy duty sliding
rotator recovery units, and contacted Null's Recovery & Site Restoration to respond to the scene with their road closure
equipment and service truck.
Upon arrival, a loaded 53' van trailer being pulled by a Volvo tractor was found to have attempted to cross a 10 ton
bridge on Old Limestone Road. The trailer did not successfully cross the bridge. The trailer tandems hit the wall of the
bridge, causing them to be torn from the slider rail. The driver then attempted to back up causing the tandems to shift
sideways. The tandems came to rest at approximately a 50 degree rotation from where they are supposed to be and
approximately six feet further front from where they were supposed to be.
The trailer was still on the bridge.
The roadway was blocked.
The township road crew was enroute to the scene to asses the situation.
The State Police Commercial Motor Vehicle Inspection Team along with the Portable scales were enroute to the scene.
At that point, our skid steer loader and forklift were dispatched to the scene. One of our rollbacks was dispatched to the
scene to transport the damaged tandems from the scene.
The rotator was set-up on a work platform and prepared to lift the trailer. The rollback was positioned so that once the
trailer was lifted, it could winch the damaged tandems the rest of the way out from under the trailer. The trailer was lifted
and the tandems were removed. The tandems were secured and transported from the accident scene to Null's of
Our flat top tandem axle dolly was then loaded and transported to the scene.
The rotator then repositioned the trailer by sliding and rotating the boom so that it was clear of the bridge and so that
the unit could be moved off of the bridge.
The rotator then hooked to the back of the unit. The unit was moved off of the bridge in a tiller fashion. It was moved to
a wide spot in the roadway so that there was room to work to install the flat top dolly under the back of the still loaded
The rollback unloaded the dolly at the rear of the trailer.
The rear of the trailer was lifted by the rotator high enough for the dolly to be rolled in position and clear the ICC
bumper. Once clear of the ICC bumper, the trailer was lowered. The skid steer loader was used to position the dolly.
Once the dolly was properly positioned, the trailer was lowered completely onto the dolly. Blocking was put in place to
ensure that the dolly was evenly loaded in order to prevent any shifting during transport from the scene. The dolly was
chained, cross chained, and strapped to the trailer. Air lines were installed from the tractor to the dolly.
The rotator was returned to travel position. The rigging that was used was removed from the trailer, inspected, and
returned to its respective location.
Our equipment then escorted the unit from the scene back to our facility with one of our operators driving the unit.
Several of the intersections had to be controlled to ensure that the turns could be safely made without causing any
shifting to the dolly and or trailer.
Once back at our facility, the unit was placed on the PSP portable scales so that a weight could be obtained on the unit
in order to determine how much overweight the unit was when it crossed the 10 ton bridge.
After PSP had finished with the unit, it was moved to our loading dock so that the load of fertilizer and grass seed could
be unloaded and placed into our warehouse to ensure it stayed dry.
Three of our laborers worked with the pallet jack to stabilize the cargo which had shifted as a result of the collision with
the bridge as it was moved to the rear of the trailer to be unloaded by the forklift and then moved into the warehouse.
Once the trailer was unloaded, it was moved to our storage area.
The securement equipment was removed from the dolly and the trailer.
The rotator lifted the damaged trailer off of the dolly. The skid steer loader then moved the dolly out from under the
trailer. The dolly was then loaded onto the rollback and secured to be transported back to its proper location.
The trailer was lowered onto the ground. The rigging was again removed and returned to its respective location.
The tractor was disconnected from the trailer and placed in our secure storage yard.
The damaged tandems were placed in our secure storage yard.
