jdfordhd Posted July 28, 2014 Share Posted July 28, 2014 (edited) If someone has already posted this, I apologize. If the link does not show it is because I cannot copy and paste on this forum. Search "truck carrying huge beam". I think the escort controls (wirelessly) the steerable dolly. The truck driver controls the throttle and his rear view mirrors. Looks like enough blame to go around. Dolly hits cushion rails at the end of the row of Jersey barriers.

slpwlker Posted July 28, 2014 Share Posted July 28, 2014 That dolly was not steerable. Seen the vid. He saw it just before contact and locked them down.

2stacksuperdog Posted July 28, 2014 Share Posted July 28, 2014 I saw that this morning. On another note they hauling in the bridge beams for the Pearl Harbor Bridge (Q-bridge) in New Haven and some are coming on regular dollies and some on triaxle truck frames. Interesting to see. Regular frames with rearends on hendrickson suspension.

mack mhe9 Posted July 28, 2014 Share Posted July 28, 2014 There was a beam down over the bank on I-93 north in VT about the 50 mile post last month.

gearhead204 Posted July 28, 2014 Share Posted July 28, 2014 the question is did it slip in the turn or was it tracking off to the right before he made the turn?

jdfordhd Posted July 28, 2014 Author Share Posted July 28, 2014 (edited) Slpwlkr, the dolly is definitely steerable. You can see the hydraulic cylinder that does it. The sun is gleaming off the rod on the cylinder. The oversize load sign is draped around the pony motor box. The dolly was steered to the right to make the left turn and had not fully repositioned to straight forward. Edited July 28, 2014 by jdfordhd Quote "If it ain't got a motor, I ain't interested.!!"

slpwlker Posted July 28, 2014 Share Posted July 28, 2014 Maybe it was but it definetly wasn't in steer mode. It never turned from what I can see. They only steer them when they need them.

mack mhe9 Posted July 28, 2014 Share Posted July 28, 2014 Doesn't it look like it hits the curb on the pass side? You see it just in front of the dolly then out the back side. He might have seen it just as it hit and was going for the brakes?

He might have seen it just as it hit and was going for the brakes? You have to look close. The bridge is under repair. The construction crews have lined both sides of the traffic lanes with concrete "jersey" barriers. This gives them the protection they need to work on the bridge. This has reduced the width of the highway to traffic lanes only, no shoulder. By federal construction guidelines, the "jersey" barriers must be accompanied by energy absorbing crash cushions (called impact attenuators) at their ends. The cushions are visible, left and right. Watch the truck tires line up on the center line going straight ahead. At the same time the right side dolly wheels settle in straddling the shoulder white stripe. Someone was asleep at the controls..! The dolly tires then strike the crash cushion. The cushion performs exactly as intended as it "accordions" to a fourth of its original length. What appears to be a curb, after the crash, are the rails that guide the collapsing components of the crash cushion. There ya go..!! 1 Quote "If it ain't got a motor, I ain't interested.!!"

Phase 1 Posted July 29, 2014 Share Posted July 29, 2014 Agree with farmer the dolly got out of line when coming out of the turn.Yes it looks like it is tracking straight behind the tractor before the turn, but the beam turned on the dolly when it was pulled around the corner.

Popular Post other dog Posted August 2, 2014 Popular Post Share Posted August 2, 2014 I was pulling a bridge girder on a dolly once and when I went south on rt.29 in Lynchburg the dolly driver decided to take 501 north for reasons unknown. He got it off the road halfway into the grass but I stopped before any damage was done or he went too far.We had one dolly that the driver controlled from the cab, but I never pulled that one.Pulled this one a lot- it was made from a Mack truck chassis.This beam was 150' long, went to rt.840 around Nashville. Pretty easy trip though, the only time we had to use the dolly was from the Carolina Steel plant in Abingdon, Va. to I-81 and after we got to the jobsite.I hauled lots of shorter beams to much harder places to get to. I think we had 3 of these old dollies, the big remote controlled unit, and 2 smaller hydraulic ones. These were a real pain in the ass to use, we carried two big wooden blocks to pull the steer axle onto, then you had to chain the axle to the beam to keep it off the ground, then use two chains criss-crossed to get the dolly straight, and every time you had to "drop the dolly" you had to get the blocks out and pull onto them to unchain the axle, then unchain the criss-crossed chains, drive the dolly, then redo every thing. Pulling them wasn't so bad, but I hated driving them.The hydraulic ones were my favorite. They had two hydraulic cylinders that turned a bolster on a platform on a tandem axle. Had a gas motor to run the pump, and you just moved a lever back and forth to turn it. All the driver had to do was run back there, start the motor, jump on and steer. When you got around the curve, you just had to get the dolly back straight, cut the motor off, jump back in the truck, and you were off. I liked to run those.Here's the hydraulic dolly at Banker Steel in Lynchburg. 4 Quote Producer of poorly photo-chopped pictures since 1999.

I've never pulled 'em, but I've lifted a hundred of 'em over the years with my cranes. Watched the steerables in lots of nasty situations.!! Quote "If it ain't got a motor, I ain't interested.!!"

Popular Post other dog Posted August 2, 2014 Popular Post Share Posted August 2, 2014 After viewing the video otherdog, was I close in my assessment of what happened? I've never pulled 'em, but I've lifted a hundred of 'em over the years with my cranes. Watched the steerables in lots of nasty situations.!!I would say so. The dolly was tracking to the right, and he should have seen that in the mirror when he made the turn and got straight, but it looked like he was pouring the coal to 'er. The escort should have seen it, but they got the left lane right away. The brake lights came on just before it hit. He might have cut to the left lane and missed it but it was probably too late by then, a sudden move like that could twist the beam too. Those girders can support a tremendous amount of weight- when they're sitting up like he was hauling it. If you layed them over on the side and tried to pick it up it would bend like a horse shoe. 3 Quote Producer of poorly photo-chopped pictures since 1999.
