2stacksuperdog Posted June 9, 2013 Share Posted June 9, 2013 I like short trailers but with frames. Quote Matt Link to comment https://www.bigmacktrucks.com/topic/28785-chicago-r-models/page/31/#findComment-187641 Share on other sites More sharing options...
Lmackattack Posted June 9, 2013 Author Share Posted June 9, 2013 On a side note...a frameless or 1/4 frame dump trailer has less chance of flipping the tractor over if it goes over. Frame trailers tend to pull the tractor over or damage the frame of the truck...The bad part of a frameless is that all the weight of the trailer goes to the rear axel when dumping. If the ground is soft you have to be real careful. 1/4 frames are much more stable on soft ground. Not sure if it's still true with todays new dumps...but a frameless could raise higher and thus the load would not get stuck in the nose as easy as a 1/4 frame or frame dump...if you ever watch a frameless raise up you will see that some of them will have the spread pan nearly touch the ground and the front axel will be over the tractors rear rear axle. Have seen a few guys set the back of the trailer flat on the ground...aka "rocket man!

blackdog2 Posted June 9, 2013 Share Posted June 9, 2013 Mack has no free play in its suspension not like air ride .The bag stretches out then the counter weight axels start to work then its to late.

57 bcr Posted June 9, 2013 Share Posted June 9, 2013 This R-model looks like an o/o pulling a John Brady trailer. I don't think this is a company truck, but I could be wrong.See that guy everyday,Brian.He pulls out of Yd.5.yes he is an O/O.

RFCDrum Posted June 9, 2013 Share Posted June 9, 2013 Yes. A quarter frame and full frame tandems stay on the ground, while a frameless balances on the rear axle.I'll post a few pics for illustration purposes. The green R-model is my Dads old truck with a frameless Axledump trailer. You can see the front axle off the ground. The two shots of the conveyors are me dumpinginto them with a quarter frame. You can see the wheels on the ground. Quarter frames are good forconveyors or paving. The yellow Pete was my old company truck and I was picking up a new full frameEast Genesis. This trailer had a spread axle on it and when it was loaded the front axle would come offthe ground an inch or two when dumping due to the frame flex. Also like Mackey said the quarter andframeless come in handy when your tires are spinning. Just hold the Johnny bar, let the box down andtry to walk yourself outThose are pretty cool pics using the coal chute into the conveyor.

Lmackattack Posted June 9, 2013 Author Share Posted June 9, 2013 It happens when you have a stuck load or you forgot to open the tailgate. You back up,stab the brakes and if you do it to fast it sits down on its end,and pulls the tractors rears off the ground. Hopefully it comes to rest upright. That's the easy part...trying to get it back down without rolling it I don't know...haven't done it yet.

Lmackattack Posted June 9, 2013 Author Share Posted June 9, 2013 Thanks, the conveyors, pump trucks and stone slingers have really taken off around here in the last twenty years.Alot of that stuff would have been shoveled in by bobcat years ago but now its just easier to rent truck for a couplehours and be done with it. They work pretty darn good.Does the stone flow pretty freely outbthe coal shute or does it jam up a lot?

Popular Post PVASS Posted June 10, 2013 Popular Post Share Posted June 10, 2013 (edited) Here are three photos of a 1968 Mack Truck Model R685T that I photographed in May 2013 at the ATHS Truck Show at Maggio's Truck Center just south of Rockford, IL. This truck belongs to Tom Bisognani & Sons. Really a nice truck!Paul V.

I moved 7 pices of equipment for them yesterday and was talking to the laborer and his dad worked there for 35 plus years started as a stake pounder and ended as on of the vp's. there were 5 members of his family that worked for tjl. There trucks were always clean for being a dirt contractor.

95k1500 Posted June 20, 2013 Share Posted June 20, 2013 A friend took these pictures of this monster truck for me. He was at Ritchie Bros. in Morris IL andcame across this beast. Although this truck is probably not from around here, it still looks cool. I am almost sure this truck has been for sale in the Truck/Equipment Trader somewhere in WIS.It's here now till it finds a new home.I believe I saw this one hauled off on a low boy Monday.

57 bcr Posted June 23, 2013 Share Posted June 23, 2013 Gonna call this truck a northern IL R-model as it spends its time around the WIS/IL border. This R is owned by the Delong company and is used to take chemicals out to their field sprayers. They have 3 or 4 R's that look similar. This one must have had some leakage issues as it looked like their was a tube of caulk spread around each cab light.I like their paint scheme,Brian!
