A friend of my father’s got the contract to haul ash from the Conemaugh coal fired electric generating plant near Seward, PA in the early 70’s. He bought a pair of off-road Macks with 16V-71 Detroits and Allison trannys, and built huge dump bodies for them. The ash, or flyash, was hauled several miles up a sloped valley, and dumped. I can still remember the sweet roar of those 16 cylinder Detroits from 5 miles away on a cold still night...
Very cool story. Thanks for sharing. My childhood home was about two miles from a Chrysler transmission plant. They used to plow their lots with Detroit powered Trojan loaders. Despite the distance they sounded like they were right in our backyard....especially on a cold and still winter night. Fond memories for sure.
I ran 2 different DM 800 MACKS in the Seabees ,they both had winches to bring up the front of the trailer and you had to unscrew the kingpin to unhook the trailer. One had a 6 in it the other a 8 in it .At 19 years old and hauling heavy equipment around I felt like a big shot.
I've still seen them used by megamovers. They'll pull an old building off the foundation and put it on this really wide lowboy looking thing with a ton of wheels and move it across town. Sometimes with 2 of these chained together and pulling in unison.
I worked on Great Lakes bulk cargo freighters while in college and all of the diesel ships I worked on started the main engines with air. The M/V Burns Harbor (1000' long, 105' wide, 56' deep) had 4, 2 stroke, turbocharged, EMD 645 model V20's (12,900 CID per engine) that were started with air. Some of the old Canadian Pacific ALCO built locomotives had 251 V12 ALCO's that were air started. Still a really cool video.
I live near where this truck used to be based and saw it in action once. I heard the engine roaring under a load (you know what Detroits sound like when pulling) and turned to see this truck hooked up to an amazingly large trailer and even larger payload (I had no idea what it was) passing by. Quite a sight!
Bob Mann there was a company in Australia that used 8V71s in W model KWs on heavy haulage of loads around the 210 000 pound gross mark with 16 sp Spicer trans. The trip times were quite good 3.5 days to do 1100 miles.I can never understand how some guys can't get a Detroit to pull the skin off a rice pudding and yet others are unreal in what they achieve.
I remember when this thing was painted orange. I actually met the owner of this outfit in Massachusetts a few years ago. They have a building with nothing but Mack trucks in it. Incredible. He was a very nice guy. I have some neat photos of that day.
I think that is the same engine as in the Terex R50 dump truck it would make you jump every time if you were near it when it started with the air starter i think it's the high whine that does it.
I’ve been lucky enough to drive some of these Big Mack’s. In 1989 I went to work for an outfit that had 8 of these. 4 were oilfield bed trucks with around 400 inch wheelbase and 4 were Prime Movers like this one. When we needed to pull, we had a concrete and iron box that weighs 188,000 lbs that would pin to the frame and we’d pull millions of lbs of drilling rigs, often two of these hitched together. We had two 250 ton trailers we could merry up and pull side by side with a single or two of these Mack’s side by side. V16 71 series Detroit’s with a 6 speed Allison and a “power tower” to run the winches. Amazing trucks.
Somewhere, someplace in the mall parking lot surrounded by his cool Buddies there is a kid in a rusted Dodge pickup truck with a super tune on it saying " I have more horsepower than that I can tow it down the street."
I worked for the company whos owner owns that truck.. Hes a Mack collector who owns close to every model Mack ever produced. After seeing the vid I called the office to see if they knew about this truck... The secretary said... Thats Bobby starting it up!!! Then I looked closer and sure enough.. theres Bobby directing the driver into the gate... Hey Bob!! That was one of the best places I ever worked. It was time for me to go on to other things but I still call once in a while. Bob was the best boss I ever had. I always try to treat my guys the way Bobby did.
Yea... love your site by the way. I started trucking in 77. Was an OO from 80 to 94. Got out for a bit. Then went back 97 to 07. Completely out since. When I miss trucking its the 70 and early 80s. You always have great trucks. Thanks for keeping up the good work.
OMG I just bought one of those. Passed it in a yard rusting away close to the mines in St Anne Jamaica. Asked the guy how much and he said give me a money and take it. Seems his dad had bought it from LBERTA , Canada and then passed away and the son had no interest in trucks. The thing was full of wasp nests and some critter had nests in it. Has a DD6 with some sort of funky Mack tranny. We drained the oil put some new oil in put a battery pack on it and it turned FIRST time . Thinking of posting a build video. This Thing is MASSIVE!!! turning it into a 60 Ton dump truck.
patience little grasshopper, lol. Not done yet. In fact very far from being done but when its done I will.Thanks for the interest. They are great workhorses.
That thing is immense! I've never seen something so big with a fifth wheel before, all the big moves now are done by ballast truck and drawbar... You've inspired me to do some googling for more pictures and videos of this tremendous machine. Shame that they seem to have used a standard-sized cab, I would have loved to see a full-width cab. Hmmm... long-length sleeper cab? It would be big enough to have multiple rooms!
Hallamore the pride of Mass with incredible equipment and have a museum at their shop . All their trucks are beautiful and even working trucks are pristine !
That is a beast! Love the average speed 22MPH! Like who in their right mind would want to go faster in this thing while pulling a load like 800,000lbs? A damn fool that's who.
The truck was empty. East to West on that route is almost always driving into a stiff headwind. Streamlining was not important for this machine.Streamlining is pretty ineffective below 35 MPH. Above, it makes a big difference.
Of course I love this Mack M45 but the K100 you have as a picture is AMAZING. Nothing better than the BJ and the Bear truck, except for a Dodge CNT950 Bighorn
What a beauty! Now THAT'S a truck! I love Detroits. Would love to hear it out on the road. Don't know why this just showed-up in my feed, but glad it did. Thanks.
That's a sound I haven't heard for twenty five years, A air starter. When I worked as a mech/welder in the mines in Az. , all the haul trucks were started by air.
bad ass truck love the video. a crane company 1 mile from us has a couple of these in their yard with the rear facing the street ive always wondered what they are with such huge tires.
For all that don't know hallamore is a multi million dollar crane and transport company based out of Holbrook mass they still have a few like this more modern though they have 16 axle custom trailers they haul transformers and anything else you need moved that weighs a shit ton the owner has all his trucks custom made by Mack for heavy hauling and keeps his Mack antiques in Hanson mass I used to work for a heavy duty restoration shop and we painted all of their trucks,trailers and cranes they are a monster company
Believe it was these guys that moved a crane I ran during the “Big Dig”. Used a Mack prime mover and a rail trailer. 4100 Manitowoc with house, gantry, cable, boom heel, car body, and tracks. Just picked it up and went with it. Not even a grunt or groan.
We have one of these at the shop at ICG in Eastern KY to move the ADD Car Miner (highway mining system) it's a Detroit 16v71, the highway speed is a whopping 24 mph empty or loaded. I'm going to post a video of it and a custom built Mack truck that is used to haul heavy mining equipment that our company uses and it's got a caterpillar 992 loader engine in it!!
Biggest air start I've seen on the road, but on a the 1000' long, Great Lakes freighters, I worked on we usually had 4 (two per propeller) two cycle, turbocharged, V20, EMD, 20-645-E7's (3600hp, same engine as a SD45 Locomotive) that were started by air. There were a few locomotives that air started but the majority use batteries.
