AUS CMP tyre loading ramp

[cliff]

looking at the underneath of the spare tyre in your photo BSM and as I have the same photos it is possible that the exact same type of ramp as a normal CMP was fitted.

Thanks Bob and Cliff. Bob I take your point but I still do not see an attachment point and I have the advantage as I have the Tractor. Same deal Cliff, each tyre compartment is separated and does not have the depth for the "ladder" assembly you allude to. Please see attached image. Regards...Rod

Not to hijack the thread but don't those wheels on that CMP look like the ones on my 20CWT trailer that I'm looking for?

[cliff]

Rod I have looked at all my photos again and it appears the spare wheel sits higher then the compartment floor so perhaps it is one of 2 things.

First it may be just a short ramp to allow the crew to get the tyre down to a safer level to lift

or

It was a telescoping ramp in two parts unlike the normal CMP one.

Thats the best picture of the tire rack assembly i've come across. It'll certainly help fabricating one.
The ramp is only as long as it is to reach that bottom "C" channel the bars lined up with it above the "C" channel is not the same piece and is a flatbar fixed in place.
As to the tires... That truck would have duals on the back if it has those wheels I would hazard..

Rod, Maybe the gun crew just lifted it into position.

There was always plenty of manpower available to manhandle the gun etc. Is there anything in the description about the No.6 usage directions. (and NO I don't have a copy, I don't even know if one exists.)

The No.6. is certainly looking good.

Regards Rick.

The #6 bofers tractor had single wheels all round as did all other models of Australian CMP except SWB tippers which often (not always) had civilian pattern duals on the rear. I have photos of tippers with civilian pattern rims and tyres, Duals at the rear and tippers with singles all round, combat rims and directional tyres. All Aussie tippers were based on the 134in SWB 3 ton chassis.

I have seen post-war pics of No6 CGTs fitted with dual rear wheels, a field mod no doubt. One of the more interesting roles for surplus No6 bofors tractors was removal of the rear body and addition of a crane for conversion to "Metropolitan wreckers".

As carrying a spare barrel is desirable for an automatic weapon such as the Bofors, is there provision on the Aust No6 Tractor for a spare barrel to be stowed from the rear of the body, and would/could a tyre ramp have been carried in the same way?

Cliff I have been corresponding with a chap in Sydney who actually drove them in the early 50's. He vaguely remembers such a two piece ladder/ramp on the deck area in the above image. He also remembers the tried and proven method of simply turning it loose and wait until it stops bouncing. In a Unit I was in we had an old International (long nose) semi trailer and the spare was bolted to the curved front section and we used a similar method to dismount the wheel.
There is no room for a ramp under the tyres in either compartment. There is a large pivoting arm mounted at the top of both which prevents lateral movement and each has a steel chock at the bottom with sliding bolts that accept a padlock to secure and hold the wheel in the other direction.

Re your "standard" CMP, 2 piece suggestion...here again I haven't seen an example. The images so far indicate a single piece construction. Add to this is the recent comment from the chap I mentioned above that they recently traded a spare wheel assembly from North Head and it had a single piece ramp. Rod

Harry they are ex Unimog, 10.50x20's, purchased on ebay from a fellow up North. AUD350 for 5 plus 2x winter treads which we passed on. Not the best profile but necessary. Rod

Not your wheels and tires but the wheels in the picture of the tire carrier in Australia. Exact same wheels on the loading ramp and the front wheel of the CMP. Same as on my thread of looking for a spare for my 20 CWT trailer.

Not sure where this came from but I believe a collection in Europe.
Looks to be a tow-truck but it is definitely the exact same tire carrier this time with a regular 20 inch CMP wheel.

Different truck, same tire carrier.
