Pup trailers

Paccar engines are Cummins and what about Detroit?

Paccar PX5, 7 and 9 are rebadged Cummins. Cummins will also build 4.5 and 6.7 engines in the Mercedes factory in Stuttgart to replace Mercedes smallest 4 and 6 pot engines. Scania adopted the Cummins 6.7 in their lighter trucks.
But the Paccar MX11 and MX13 are designed and developed in Eindhoven, the Netherlands.

And right on cue, we go from a discussion about pup trailers to being schooled on the superiority of European thought and design…

Those are your words. But the American industry did fall behind because of the commonspread idea of using EGR and soot filters to avoid DEF. It allmost bankrupted Navistar, and killed their engine production.

When it became obvious that nobody could achieve emission norms without DEF, Cummins was ahead because they already sold DEF equipped engines on the European market.

So no superiority, just poor business decisions because none of the US truck makers is active on the European market and vice versa, so both competition groups developed in different directions, with Navistar CEO Dan Ustian yelling his competitors nuts that they would be having a non-DEF engine, which his engineers said impossible.

Death By Hubris? The Catastrophic Decision That Could Bankrupt A Great American Manufacturer

One of America's most storied manufacturers, $14 billion Navistar, survived the Civil War, the Depression and World War II. A stubborn decision by its CEO has jeopardized its future

The way Navistar was in the game, damaged an entire industry by keeping most of its North American competition on an evolutionary dead end for too long. Its just tragic.

Those are your words.

Just my observation. You push COE trucks and that’s what the European market wants. The American market prefers conventional trucks. The manufacturers will produce what the market wants.

Getting back on track, here is an example of a pup with a tandem axle dolly/converter - much more stable in turns on rough terrain. Disclaimer - not my picture. I surfed this up on the net.

No, i show you guys the European perspective, i thought you might like that, as much as i enjoy reading about the North American perspective.

Interestingly enough, the Australian and NZ market is the only market where trucks from three continents are sold: European, Asian and North American. So it is interesting that Australian truckers are slowly accepting European cabovers for the long haul, where a decade ago, this was the sole territory of US designed (and even locally assembled) trucks.

And the manufacturers dont allways produce what the market wants: Henry Ford said: "If i had asked customers what they wanted, they would have said faster horses"

Re: cab over trucks in the US. They mainly went away when the allowable length laws were changed. I may be wrong because I was out of the industry during that time but wheelbase and bridge laws may have come into play? Same way with conventionals running setback front axles?

Then there was the idea about being the first one on the scene of an accident, replacing the windshield after failing to secure some item and then jacking up the cab to check on the engine, etc.

The old cab overs are interesting to look at say at a truck show like in Macungie, PA but having driven a number of miles in a GMC Astro, an F model Mack and a Mack Cruisliner, good riddance.

Anyway, back to the topic, sorry to digress.

Heres another pup trailer: This is a Finnish combination, of a 20 ton truck and a 40 ton trailer: Reason for this is because Finland allows 20t GCW on snowed roads in winter, and 60 ton in summer.

The truck is a Scania 142 V8, which has a cult following in Europe, its predecessor the Scania 140 was the first production truck in 1969 to hit the 350hp mark in Europe, with its 14.2 liter V8 and 970 foot pounds of torque at 1450rpm, which was unheard of at that time

It's amazing to think of some of the old trucks and nerve it took to drive them. The 1943 Kenworth I mentioned before was crude compared to trucks of even 40 years ago. The cab wasn't much wider than a VW old Beetle and had a bench seat. The sleeper was literally the width of a coffin and accessed from the outside by a door on the left side. I never drove it but my boss said it was a 4 & 4 square tooth no synchro transmission. The parking brake was a compression band on the driveline and operated by a cable. No front axle brakes and 185 horse power.

18 years ago at one of my first jobs after school, at a nationally operating road construction contractors service branch, one allmost retired mechanic remembered his days at the Daf truck dealer: rebuilds were frequent in the late 60s and that was before tilt cabs: you had to unbolt the floor to access the engine and adjust the valve clearance every 100.000km. For a rebuild, you better take off the entire cab...

That shop was founded in 1965 and they ceased it 10 years ago: probably because knowledge was gone when 70% of employees retired over just a couple of years...

But my goodness, when those asphalt paver operators come to the shop in winter time with their machines, and you hear all the banter about what they have seen out on the road in the past year.... it was a great experience

Heres another row of pup trailers: the Swedish are experimenting with 90 ton logging road trains to reduce cost (off course in todays culture you must say its better for the environment to get legislators moving)
