Feb 24, 2011 · Furthermore, under 1-12. EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES, it states "The M870 and M870A1 semitrailers are used to transport construction equipment and materiel and are towed by an M920 truck tractor. Either semitrailer can also be towed by an M916 truck tractor using the adaptation kit listed in TM 9-2320-270-34P."

Oct 23, 2014 · After several years of looking for one, I finally found and purchased a M870A1 40 ton lowboy semitrailer for my M916 tractor. I had Soni (aka M920) take it from Oklahoma to New Mexico. The trailer did not have any lights or electrical, brake components were missing and no air lines were present. The tires were in sketchy condition.

Mar 23, 2011 · As part of the refurbishment process on my M870A1, I need to purchase new wood decking for it. I know the trailer manufacture Load King uses full 2" rought cut Apitong on all their trailers, but what other suitable alternatives are there for a 40 ton lowboy? BTW, Local prices on Oak are almost as much as the Apitong from www.trailerdecking.com

Jan 7, 2010 · The museum only has an M870 and M870A1, both of which have 10R15 tubed tires. Neither the M870 or M870A1 have folding ramps, but rather removable ramps that weigh about 300lbs a piece. The trailers, or at least the M870 and M870A1, are manufactured by Load King, and are based off a commercial trailer design.

Oct 22, 2014 · A few updates. M35A2-AZ came over and we (he) welded up a few additions and we fixed a lot of little dents on the trailer edge by heating and beating them straight.

The m870a1 has a 36in deck height behind a 916 or 920 on a 3.5in king pin plate with 10R15 Dayton tires at the neck. Rear of the trailer deck is 41in over the rear most tire. You can go with a 235 75 17.5 tire on the rear which drops the rear of the trailer down some.

Jan 14, 2020 · The Holden MTO-020 EET and Load King M322 Trailer both use a hub piloted setup on the same 25k axles. The axles are the same tube diameter as the M870A1. So a direct swap of the whole axle is easily done on the front and the rear axle. The middle axle has the track bars on it so you would have to reweld those brackets and set the track.

Oct 22, 2014 · The "official" tractor for the M870 or M870A1 should be the M920. The 920's GVWR and GCWR fit the 870's numbers correctly. I don't think the 2" kingpin for these trailers is a usual military item. The 5 ton tractor doesn't have a rear winch and really doesn't have the ratings to utilize an 870.

Mar 21, 2016 · There is no part number, because there is no 2" M870A1 kingpin. That is, to say, there is no stock/OEM 2" kingpin. The trailer was designed for the 3-1/2" fifth wheel tractors. To my knowledge, all of the A1s were manufactured by Shoals American Industries, which no longer exists, so you can't go to them for parts..
