weight limit for 5-ton axle - Steel Soldiers::Military Vehicles Supersite

I am thinnking of build a single axel 5-ton tractor and was wondering what the actualy weight limit was for one of these axles. Up here in Kentucky we haul alot of cattle and I was wanting to shorten a truck to make it easier to get in and out of feed lots. Would the 5-ton axle be strong enough?

Just going by what the data plate says on the M923A1 empty weights on the rear axles is 5995, and loaded is 10995, or 5,000 pounds each.

When figuring an axle's capacity, it's not just the structural capacity of the AXLE ASSEMBLY but also the SUSPENSION: Springs, AirBag(s), SwayBars, etc. that MUST be considered. I presume that you will be changing that "rigging" also.

BRAKE DESIGN and potential is also a CRITICAL Factor.

yes I would be changing the rigging. unsure yet of wether to use spings or air bags. I dont think the brakes would be a big problem. it would be nice to have an airbrake axel but i wouldnt have to

DOT doesn't care about the structural integrity of things. They will only look at the tire loading. Here, you get 550#'s/ inch of tire size. On the steering, you get 600#/ inch. So on one 10.00x20, you get 5500#'s . They also don't care here, about what the pound rating on the tire. They just go by inches, and tire width.

Maybe the actual M931 Tractor tag helps a little.

those numbers seem pretty low... most tractors today haul 80,000 or more

would anyone feel comfortable putting 40,000 on one rear 5-ton axle

This is gonna jump into the other hauling thread really quickly.

80,000 is the truck + trailer + cargo weight combined and rolling down the road on 5 axles.

80k is
12000 front axle
34000 on the truck tandems (17k each axle)
34000 on trailer axles (17k each axle)
Thats how you get 80k

I haul for a living and have a heavy haul truck with drop axle and stinger trailer. Now that's all new ball game on weights and permits.
