Hello George,
I think this would be the one: tm5-5910c.jpg Hereīs one in action on the Alcan Highway in Alaska: 4101637853_f3de449e22_b_jpg_f804cecc5b237e188017649207fc0b21.jpg 4104263010_1edd0435d2_b_jpg_55efb224a167913c4dd7f53453fe7566.jpg HTH, Hanno

here is a couple of oddies for you to think about
1. a specially developed trailer to carry the RB19 excavator, the tracks hung down the sides of the centre frame whilst in transit 2. A pre war light trailer which from the photo has been built to fit the light Cleetrac tractor comments welcome cheers Les

Trailer
I have seen one in a farm in Cornwall, about 40 mins drive from home.
The trackways have been widened and air brakes fitted, but pretty much original. The tyres are 10.50 by 13, split rims 6 by 13. The vehicle data book also quotes this tyre size as standard. And yes, the owner tells me they real bu##ers to source. Les, have you found out any more on the Taskers folding trailer? George Moore.

Call for help from Australians.
I have just started to restore this Dodge D60L. Issued to Australian forces in Middle East 1942. Originally with single 10.50X16 wheels. About 1,500 of another order were issued with dual 7.50X20 wheels. I have the option of either but will be going for the duals as I want to make it a semi trailer prime mover. I need information on the wherabouts of a WW2 semi, preferably the round nose type but square would be OK. Any condition. Trying to get it ready for the big Military Jeep Club weekend at Canungra in October. Three photos attached. 1. The Dodge as it is now. 2. WW2 photo of same vehicle with square trailer 3. WW2 photo of a Ford attached to my preferred option round nose trailer. Lang Last edited by Lang; 14-06-06 at 05:15.

Thanks, Hanno P.S.: didn't John Belfield have a trailer of this type? I vaguely recall seeing a picture.

Cliff,
Lost your email address from my address book and it does not seem possible to attach a photo to a private email using the MLU personal profile link. Email me and I will reply. Have two (via Keith Webb) really nice sharp, big photos of the Dodge D60L semi - one from the side and one from the rear. if anyone else wants them let me know. Lang

Well, this thread took off like a rocket but lost steam before it reached the moon. OK lets see if we can get abit more movement here is a comparison shot of the 40 ton Rogers and the MK2 Dyson 40 tonner

OK guys i need a bit of help with this photo of a generator trailer, the info i have states it is captured from the Italians in Libiya, taking a second look at it is it a generator and what are those air bottles at each end maybe its some type of dry air charging unit. Note the fexible exhaust on the frame lets see what you can come up with
cheers Les

Les,
I will take a punt on the Italian trailer. Looks like a power unit for a workshop or headquarters complex. Probably had a tent system to attach to it, hence the flexible exhaust to position the gas away from the boys according to the wind. Most likely an air force unit because of the spark arrestor on the exhaust. The tanks could be a. Welding gas b. Nitrogen for aircraft landing gear c. Air for an air start motor (but why so much?) d. General use compressed air. Welding gas or general use air seems most likely as the tanks don't look very high pressure. Then again it might be a power unit for a canteen and the tanks contain CO2 for the beer taps! Lang

Cliff,
Oxygen has to be made in a large plant and can not be produced in the field. Actually it can now (medical home breathing units for instance, but they are not high pressure to fill tanks) but they did not have that technology widely available then. Aircraft breathing oxygen tanks would have been topped up from banks of cylinders filled at the factory. Those 4 tanks would not have enough in them to fill more than a squadron of planes. Lang

Mind you these were semi trailers and not the smaller trailer as Les has shown & would be a neat model to make one day  cheers Cliff

You are dead right there and I am wrong about in-field oxygen generation plants, but as you say, at that time they were extremely large.
The Italian trailer still has me tossed. The thing I find interesting is the strange rack. Looks like a bank of fittings or taps? On a good look the fairly small engine seems to be driving a compressor as it is a big square arrangement unlike generators which tend to be round and smaller than the engine. The radiator seems hugely excessive for such a small engine, maybe it had a water-cooled compressor? If you look closely it could be a radiator at each end - one for the engine and one for the compressor? Lang

I just happen to have an original print of this photo of the Italian trailer, it is from the IWM library.
From close examination with a magnifiying glass, the power unit is at the drawbar end of the trailer, it drives a considerably large compressor, probably a single cylinder and water cooled, it is as high as its radiator. My feeling is that it is for recuperator charging, high pressure air, for guns, tanks, etc., hence the cylinders stowed. Cannot work out the three rows of fittings on the side, unless, they are for charging smaller cylinders and those stowed are acting as reservoirs. Richard

Richard,
We are really down to micro observations on this one. It seems to be a compressor by popular vote. It must be a multi cylinder operation to justify such a huge cooling radiator. The heat generated from a single compression (unlikely to be any more than 150psi) couldn't justify it. Also, if it was a low pressure unit, something that size would fill those 4 tanks in 30 seconds. Unless it was a sandblasting unit not very likely. I think you are on the right track about it being a high pressure unit for ??. If it was a 3 or 4 compound cylinder compressor it could push it up to 3,000psi ie lots of heat requiring cooling. The 4 small tanks would seem indicate something pretty powerful in small volumes not just air for tyres. Lang

The engine does not appear to be of great size, but the compressor (?) is quite large, from the web photo details may not be clear but the lower part (crankcase maybe?) is not large, denote relatively short stroke, but the upper part is as high as the radiator and large in diameter, part of this is probably the water jacket.

Lang,
I have now scanned my photo which was printed from original negative. Enlargement of the actual engine / compressor reveals more details. I am certain now that the compressor is a twin cylinder, and note the large flywheel. Richard

Richard,
I now do believe we have a field oxygen generator as mentioned by Cliff. It seems pretty clear the rack on the side is a set of quick release gas fittings with a capability to fill numerous bottles at a time. The flexible exhaust would be what you see on SCUBA compressors to enable the fumes to be positioned downwind to avoid sucking in to the system. Lang

Thanks for that, it is amazing how, when a few heads get together how we can interpret some of these old photos. Richard

Another interesting conversion for the RAF is this 20 ton SMT multiwheel low loader for use as a parachute drying van

If it was a self contained mobile unit it probably had a decent generator to power a heater (or might even have been petrol or diesel fired). Then it would need a lot of fan power.
If they put the peak of the parachutes on the ends of the beams and pulled them out tight (probably had ropes through the holes so they could haul them up and down), with a couple of chutes on each beam about 24 could be run through in a sitting. With stakes for stretching the chutes and a huge tarpaulin to go over the top (no good drying out in the rain!) and maybe a big stack of folding packing tables, I don't thnk it would take long to get to 20 tons. It might even have had a big circus tent to go over the lot creating an efficient huge drying oven. Lang
