For those of us who love to find out the history of these things, it would be great if you could do us all a couple of favors.
- First, take some close up photos of the markings and post them for us and if there are any documents you can scan, or even photograph for us, that would be great. (Also you can post larger documents in the PHOTO GALLERY section of the ForumsForums, up to 2MB so we can see the detail).
- Second, provide us with any history detail you can about this specific unit.
- Third, if the CAA used several of these, it would probably be great if you could tell us something about their general use with the CAA such as how long were they in service, what were they used for, why did they need to drive on peat, etc.
Also its very interesting that the 2 belt doesn't de-track as easily as the 3 belt. I would have never guessed that. I would have presumed that it would have depended more on the depth and design of the cleats than on the tracks?
Hi, My son I am sure will oblige with more photo's.
The CAA started using Snow Trac's in the late sixties it used them to access radar and comunication stations in both Scotland and England. They were based in Shropshire for the Clee Hill Radar, Cumbria for the Great Dunn Fell Radar and Comms site, Dumfries for The Lowther Hill radar and Comm's site this particular one was the last machine bought in the early eighties and was based in Tweedmure for a NAV site at Talla this is also the longest in service at 24 years.
It has been found from experiance of using them in the snow conditions in the UK were snow cover can be patchy that the three belt design that we first received in the early seventies that used in these conditions that the two belt design was less likely to de trac. Also in summer used when used on heather in Scotland the two belt design was better this was why machines used in Scotland were ordered with the two belt tracks.
In England were the machines were used only in winter the three belt design was used.
The Snow Tracs have all now been replaced with either the BV206 or Kasbora machines the reason for this was not that the machines had come to the end of there lifes mechanically it was on Health and Safety grounds as they had no roll cage and the fuel tank was internal.
Hope this information is useful, regards Geoff
