    Looks like it somehow pulled the rest off the dolly.

    I saw a boomlift on a rental truck swing as it went across an overpass and knock a sign off the overpass onto traffic below....

    I've never pulled that type of dolly. That style has a pintle hitch, and the boom pins to a "traveling" rest. The tower will roll back and forth on a bearing track to deal with the difference in corner movement. I would guess something in the bearing/ track assembly let loose by the picture.

    All the ones I've driven have only been attached to the dolly by the boom, no pintle hitch.

    That explains it all better.

    Crane was slowing down to make the corner, can hauler was in a hurry. Knocked the boom and tower right off the dolly, then there's nothing to keep that boom from swinging free. If it does it on the drivers side, usually the driver doesn't make it, the boom swings around and crushes the lower cab. luckily there was a pole there to stop it.

    Opened the can hauler like a tin can.

    I for one could never get my head round why permitted axle weights in the US are so low compared to the rest of the World..?

    One lucky thing was that the power pole right on the street corner probably prevented the boom from shaving the roof off the nearest house at ceiling level.

    I got a workout friday morning. Supposed to go lift a unit about 10:00, I called them and they were ready, about 8:00. I told them I'd head that way, then I did my walkaround. Looks like the hot weather we've had lately got to this tire. If you can't see it in the picture, its got about a 6" zipper forming about a inch off the bead. Nasty nasty.

    I wasn't too late for the original 10:00 time, but I certainly wasn't early.

    Got the units changed out. Set on one side of the church, units are on the other side. One of my guys was finished with his first job, close to where I was at, he stopped by and helped me do jib and dead section, and then did the radio work from the far side. In the blind between a retaining wall and the building, its nice to have someone who knows what they are doing on the radio on the other side.

    70' long wall, heavy fire wall rocked, steel studs, also all mudded fire board. foreman did the math, and told me it was a 8,000lbs wall.

    First had one of my guys with the mack try it with just the 30' bar, and the wall couldn't take the strain, couldn't keep it straight. We moved some chokers around, and I went and got the 25 ton, and we set it together.

    Architect demanded that the wall be built and stood as 1 wall, no joints. The builder is barely on speaking terms with him "I ain't ever using that architect again" is the phrase I heard several times while I was there.

    Finished up the big unit at the college this morning. They had to build a whole new steel curb to hold this unit, and somewhere the drawings were wrong, so I had to hold on for a hour or two while they redid the curb. Fit great when they got it changed.

    Some Congress Critters found the levers back in the 70's and It's been downhill from there. Part of the original interstate design specification was a 129,500 pound gross weight.

    Europe goes more on axle weights. Drive axle - 25,350 pounds; non-drive axle - 22,050 pounds. The original numbers are in metric (11.5 tonnes/10 tonnes) which makes more sense.
    Articulated truck (equivalent to US Class 8.?) - max GVW 97k pounds (44 tonnes) on 6 axles, three of which must be on the tractor, the other three on the trailer, and must have "road-friendly" suspension which pretty much everything has these days.
    Basic rules that apply as a minimum pretty much across the EU. Some countries (e.g. Holland, Denmark, & Scandinavia) allow higher gross weights but with caveats, usually more axles required.

    In the US Commercial Zones as I am aware the total Gross weight is not bothered with so long as can meet axle weights and DO NOT access the Interstate system. Bridge law still remains to dampen to free spirited. Most EU style multi axles would not fare well in the US as to Bridge Formula.

    In South Carolina, all vocational type trucks and vehicles are exempt from worrying about axle spacing, as long as they stay off the interstate. We go by gross allowed by number of axles, and no more than 20,000 lbs per axle without a permit. Divisible load, no permits available. Permitted load is still generally restricted to 20k per axle.

    That seems counter-intuitive. If the major highways are the ones that are better-designed, constructed, and maintained (at least you'd hope so) it would seem logical to apply any stricter limits to secondary highways not primary ones. Or am I missing something..?

    Yeah, well, politicians make the rules, so...

    South Carolina was one of the states that already had weight laws of a certain type, so we were allowed to keep them when the feds came out with bridge laws.

    See quite a few Oversize Overweight units on the interstates so long as stay below 14' or 15' depending on the road, Junkyard has dragged His share around MO.
    One of my First ever Mack STL road calls was for Gateway Ready Mix Maryland Heights MO. Had a Brandy New 1977 DM800(Found my notes) with a V8 someone noted was Uprated to 560 hp, had tootsie rolled the forward drive shaft. Saw the truck delivered but had not seen it close up until that day. Tri-Drive on rubber ride, 20K steer axle dual steer, 24? yard dump box could have been 30 as was at least 18 if not 20' long bed. Behind that a tandem Joe Dog to a tri axle 34 or 36' frame style dump trailer. Average Gross weight coming out of West Lake Quarry was 167,000. Drove Under I-70 but never on it to climb Creve Coeur Park Hill and hang a left onto Dorsett Road, NEVER did the driver achieve 45mph before had to slow for a stop. Had to have a shaft made for the New truck on its third DAY at work, that one made by Plaza Fleet Parts, it lasted two weeks and was BACK twisted like a bread tie. Next one to go in was either Schedule 80 or 120 Pipe cut and lathe fitted by Nooter Boiler Works STL took TWO of us to wrestle into and out of the service truck and BOTH to hang ONE end at a time, had the massive Rockwell bolted Cap U-joints. Far as I know a few busted joints but NEVER ever a shaft again.

    Bridge Law, who needs bridge law when never cross one!!
