M989a1 trailer Davit

[Oldfart]

Interesting how different the M989 is from the M989a1. Same rated capacity and load purpose, but M989a1 is set up wagon style with steering front wheels and the M989 has a rigid drawbar with the wheels centered under the load. I wonder what the deck height differences are?

 

[mdlbldrmatt135]

IIRC the total redesign was because of the deck height. When pulled behind the HEMTT and carrying MLRS pods the M989 had a tendancy to want to flip over if it hit a bump just right.

Just waitin' on the EUC on a M989A1, my HEMTT will have something to tow this summer.

BTW, the manual for the M989A1 says the davit is to be taken off the towing HEMTT for use on the trailer. The draw bar is pretty light so I'm just going to make a 2x4 of the correct length for attachment height and then drop the bar manually into the pintle. I may decide to get a self guiding hitch like Jones has on the Baby HEMTT. The manual also shows using a ratchet strap to lift the bar . . .

Scorpion is only 8.5 tons, but I MIGHT have to build up the dropped floor a bit to make one fit. Not a big deal.

How would you build up the floor? And what about ramps to get the Scorpion on and off? I am considering getting an 989a1 for towing an uparmored Saracen MK6, which weighs around 11.5 tons. I just don't know if retrofitting the floor is going to be worth the hassle. I would tow with an m923a2. These trailers look like a great deal for the money, but how are guys using them? Has anyone figured out a way to use them for hauling armor??

A little late to the game, but better late than never. Background, I'm a 13M since 2002 and am retiring this year, and am quite well versed with the equipment. Attached is the pages of the base M985 RPSTL with all part numbers that would be needed for the tire davit. Stalwart is correct, the davit is supposed to come from the prime mover. However, the newer M985A4s no longer have a tire davit to be able to transfer to the trailer, the last version with the davit included was the M985A2.

Hope this helps...6.5 years after the fact.

I have gone to the farm and picked up the manual, scanned a few pages that show how the davit is used to lift the tow bar and scanned the title page with the NSN.

There is a section that shows a method of lifting and holding the bar with one of the included cargo straps by attaching the strap to the spare tire bracket and the tow bar. It looks like the davit can also be used to remove the spare tire and lower it to the ground.

You have the whole TM? or just the change.

I have both the M989 and M989A1 TMs, as well as M985, M985A2, and M985A4, all current. Also have the base model RPSTL in 2 volumes.

Whatchu need? Lol

 

[Guyfang]

Nothing. I have lots of trailer TM's and a few truck TM's, left over from when I worked on them a bit.

I don't think we have any of the M985 Tm's on here. Are they public release? If so, Could you upload them to our Tm section?
I think we have both trailers covered already here on ss.

I have TM 9-2330-383-14&P but the ability to upload things to the TM section isn't apparently something I am allowed to do.

I uploaded that one a while ago. I know you have to have a good internet connection for the fat files as some are huge tm's

Probably to big. Or, you are not doing it right. Have you ever uploaded anything?

Thanks Juan!

Either my account was fouled up - or maybe I was stooopid but now it seems that I can upload TM's with no problem. Thanks for the link!

No sir, but it seems that it is working for me now...

Juan,

What is the TM number for the M985? I will look at my files.
