Geoff Weeks Posted February 4 Share Posted February 4 Only trailers I saw that were 24 volt were either military or gravel screen plants made in Europe. COW are small, single axle things aren't they, I am surprised they would overload 18 ga wire with only a few lights? Cars of the vintage we are talking only had 16 ga at most, I think most were 18 for the lights. 18g can carry 10 amps at least, how many lights did these things have?

The COW towers belonged to Omnipoint communications. It was back in the 90's and when they moved into a new market they set the COWs up until they could build a permanent tower. I believe these were 120 feet tall ones and all folded up for transport they were 40ish feet long. Diesel gen set up on the nose something like 100KW, and a bunch of electronics enclosures. Tool boxes full of big screw in anchors for the guy wires, outriggers on the trailer, air brakes, really a nice setup. Pretty much just standard trailer lighting, they had just changed all the bulbs to 12 volt, but the lights were kinda dim especially on the back of them. Maybe the wire was even lighter. It's been probably close to 30 years ago. They called me after some clown tried moving one with an F600 juice brake truck and jackknifed down in Delaware Quote Link to comment https://www.bigmacktrucks.com/topic/25325-connecticut-construction-trucks/page/90/#findComment-568608 Share on other sites More sharing options...

Geoff Weeks Posted February 5 Share Posted February 5 Up until Elon destroyed Maxwell, my preferred solution for 24 volt crank/12 volt run was a 24 volt ESM from Maxwell. Charges on 12 volt, provides 24 volt cranking. Completely "hands off" split charge ( transformer/rectifier) alternators and S/P switches are distant 2nd. Too many can't figure out S/P switches, and there are failure modes that leave the truck "dead". T/R alternators are ok but the battery banks don't age equally. I don't consider 24 volt crank, 12 volt run, 24 volt systems at all, they are 12 volt systems that are paralleled for cranking only. I had a service van fitted out with two 8D's down under the body and a S/P for charging. It could start a 24 volt bus with flat batteries. It could also jumpstart 12 volt vehicles. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/25325-connecticut-construction-trucks/page/90/#findComment-568624 Share on other sites More sharing options...

The railroad overpass east of what is now l-291 before it was rebuilt. You could almost remove your drivers mirror on the center support if you were in the left lane. The guard rail was bolted to the center support of the bridge. The freight haulers racing down the hill east bound at exit 100 before the rest area. OH ya! Back when it was fun. lol .....Hippy 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/25325-connecticut-construction-trucks/page/90/#findComment-568796 Share on other sites More sharing options...
