here in south dakota. belly dumps have disappeared...virtually every new trailer sold is a side dump. beauty of them, you can haul anything, use them for demo, whatever...and don't have the fear of tipping over like a 40' end dump sitting on unlevel ground. we winter in texas, and from nebraska south...you don't see them. i wonder why?

    How do you haul demo debris in a side dump and not tear the trailer tires up running over the debris? I get dirt, crushed rock, etc. but demo debris does what it wants too and goes where ever it wants to when dumped out. For the record I have 0 experience with a side dump - just curious.

    There are a few side dumps here, mostly heavy. They seem to be mainly used for hauling large rip rap. They don't work well on most of our job sites, mainly because you need a different traffic pattern for them, and if they're hauling together with end dumps or belly dumps they tend to disrupt the flow. They seem to have a lower payload as well what compared with end or belly dumps.

    I've hauled a fair bit of rip rap up to a about 5 feet in a side dump. When you pull up to your dump spot, you turn into it a little so the truck is at about a 20 or 30 degree angle or whatever your can get. That swings the drivers away from the pile a little, how much depends on 5th wheel location. Then when you dump, back up so the trailer doesn't have to run over anything. I do it with anything I'm hauling unless I'm dumping into the road ditch.

    it's surprising how far they do dump away from the side. it's common for those guys here hauling gravel, to dump on the fly. here's a good short video showing one work. i would bet side dumps in the last decade have outsold belly dumps 3:1 up here. i had a 3 ax belly, and our clay if at about 22% moisture or more....didn't work. okay for gravel/sand/dry clay. here they're using them for sand/gravel/clay/demo, snow hauling, wet material hauling. real nice thing about them, if stuff does stick to them, put them in dump position and have a skiddy scrape them out.

    in fact, there is a trucking company here that hauls aggregate from a granite quarry in n.e. so dak., to sioux falls, sd...about 150 mile one way. they pull doubles, and counting axles on the tractor....there is 20 axles. imagine replacing 40 super singles for one rig. in south dakota, they can gross 188k

    Or use a hand shovel standing with your feet on the ground!

    That would work great on a large import job. Bring the trucks around on the leading edge of the fill lift and dump quickly. Added bonus is the loaded trucks are compacting the lift as it goes reducing time for the rollers. Still could see demo debris like framing lumber and light gauge metal studs being an issue though.

    A few years ago I hired a local outfit with walking floor trailers to haul off of a wood framed building demo job. They ended using 1 walking floor trailer and a side dump trailer because the other walking floor was in the shop. The side dump was easier to load but held considerably less material than the high sided walking floor. It wasn't a big job (@8 loads total). If it would have been a big job I probably would have sent the side dump home. It seemed like the walking floor was hauling twice as much as the side dump at the same rate.

    yeah, but that's work!!!

    No issues whatsoever, as long as the guy loading it keeps the debris kind of organized into the trailer. Don't fill all the way to the front, dump in one motion so it flops out, back away. I've been demoing houses with a side dump for 12 years, would never want an end dump for anything unless working area was too tight for a semi.

    Gotcha. The majority of the time we use 30 and 40 yard roll-offs, however if I had my choice it would be a 100 CY walking floor like Bam used. You can move a **** load of debris quickly.

    Believe it or not we had the first side dump in this part of Idaho. Everyone used end dumps. I bought a truck and trailer in the mid 2000's. I got it out of Nebraska. It was a Circle R which was made there. We got on with the largest dirt contractor here, contracting out our side dump. The first job we did with them was a road job. I had a great driver, but we would lap their end dumps three to four times in a day. The next year they bought side dumps and so has everyone else here. Still are some belly dumps around, no end dumps, except for large 80 cy demo trailers. They are still the best way to haul light demo. Sometimes concrete will roll under the trailer, but you can back the trailer up, crank it around and usually avoid having to move it out of the way. If you have room, a side dump is the best "do most everything" trailer.

    The gravel pit brought me some fairly wet gravel in a super B side dump. Very fancy new trailer but not all the gravel came out. I had to shovel a couple yards out by hand.

    First time I had anything to do with side tippers was loading shot rock onto a fleet of A-B doubles and A triples, most had deforming bins, the dump side flattened as it rolled over. Others had a door along the side that folded down then the bin would tip. That job was setup for them and the only time they stopped moving was to be loaded. Effectively at its peak that end dumpers could never achieve. The outfit that ran them were pretty lean even to the point that the had trailers lifting axles and only had enough tyres on the ground to carry the tare weight when empty.
