V17s 169 159 and 167 ready to go to work, September 1969.
The booklet that came with the V17 explained how they were to be used. I am a little fuzzy, OK a lot fuzzy on remembering what it said. But it went something like, the V17 MTQ was a telephone line construction truck that was to be used in conjunction with the V 18 to construct telephone lines. The V18 boring the holes and the V17 and its pole trailer following along behind placing the poles in the holes with the jin poles using the rear winch cable attached to lift the poles as it went along. Following V17s would place the cross arms with insulators to the poles using the rotating platform. Other following v17s would, from the towed wire reel trailer, string the open wire across the cross arms. Another following V17 would complete the job by affixing the wire to the insulators using the rotating platform. The open wire would be pulled tight with a rope attached to the wire being strung, the "Cats Paw" fit onto the rear winch shaft through the little sliding door on the right side of the V17. The rear winch drum was disengaged and the rope wrapped around the cats paw and the pto lever moved to start the winch. A slight pull on the free end of the rope would tighten up the open wire or wires on the pole cross arm insulators so it would not sag between the poles. And on it goes until the line was completed. This was the basic procedure as I remember it. The V17 and V18 was designed back in the day when open wire and cross arms was used by the Army Signal Corps. A day long since past by at least 1965. They were, as far as I know, not designed to be used with telephone cable. The poles that were used with the V17s were wood and shorter allowing the rotating platform to be used with the idea that no ladders or pole gaffs are needed and the wire stringing process is speeded up in a assembly line type process. If a book could be found, I could be proven wrong here, but I do think this was the basic concept behind the V17 its wire trailer and pole trailer to carry the poles behind the V17. And of course the V18.
Korea may be the last war where this type of telephone line construction concept was used. The idea where front line troops used field phones and field wire strung out on top of the ground for communications, then as more ground was gained, another group would come along behind them with the V17s and V18s to string permanent open wire communications from the rear to the front line troops that were (hope any way) moving foward. Here is where you can see the need to speed up the telephone line construction process to provide constant communications from the rear to the ever moving forward front lines. Of course Vietnam was not anything like this, so the V17s and v18s were assigned to maintain the communications facilities that was built for the most part using more modern construction equipment used by contractors. The V17 and 18 were really obsolete for working with modern (1969) cable based communication facilities. But the military used what they had and if you needed a truck to maintain telephone lines, well you got a truck to maintain telephone lines. Just deal with it the best you can.
The contractors had the modern equipment, we had the V17s.
