Squid Posted July 12, 2008 Share Posted July 12, 2008 I'm wondering if anyone has a fairly accurate estimate of what an empty B61LST would weigh? The tractor is a single frame, camelback tandem, aluminum tank, no front brakes. It's pretty light as far as a tractor goes, but I need to get a weight to find how heavy of a trailer I need to move it. The obvious solution would be to go to the scale, but that may prove to be difficult for me, given the truck's current condition. Thanks.

Terry T Posted July 12, 2008 Share Posted July 12, 2008 Not sure of the weight, but I attempted to move my B61 s/a without body on it, just the chassis & running gear with an IHC 4700 Rollback and it was way too much for the truck. This is what I used to move a S/A B Wrecker from NE Indiana to eastern Iowa.T.

Squid Posted July 12, 2008 Author Share Posted July 12, 2008 It's hard to tell from the angle, is that a single wheel trailer, or duals? My trailer is only a single wheel, so weight is pretty critical Quote Link to comment https://www.bigmacktrucks.com/topic/3985-b61-weight/#findComment-20505 Share on other sites More sharing options...

Thanks.Hi Squid, I've hauled my B61ST on a single tire, tandem axle 24 ft. trailer several times without problems. The gooseneck trailer I use has two 7000# axles under it. The tires are good and maintained properly so if you have the same equipment available, I wouldn't hesitate!Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Terry T Posted July 13, 2008 Share Posted July 13, 2008 That trailer has singles, like Rob said, no problem, I ran along at 55-75mph all the way across Indiana and Illinois without an issue. If I ever buy a goosneck of my own, I will have duels under it, but that is just my preference.T.

Thanks.Squid,I have a single axle dump truck with a Thermodyne that weighs 14,200#. These trucks are made heavy duty, and they are heavy, even if they are a "light" model with lots of aluminum. I would say you are safe assuming 12,000 to 14,000 pounds for a tandem tractor.Scott Quote Link to comment https://www.bigmacktrucks.com/topic/3985-b61-weight/#findComment-20516 Share on other sites More sharing options...
HeyCharger Posted July 13, 2008 Share Posted July 13, 2008 For info, my B61 bogey drive prime mover weighs 7tonne (~ 6.9ton or 15,400 lbs). Took it over a weighbridge to get accurate weight.

Squid Posted July 13, 2008 Author Share Posted July 13, 2008 Thanks for the input, guys. I may just load it and see what it looks like. My trailer is a 25' gooseneck with 2- 7000# axles, and a total GVW of 15,XXX, so I should be pretty close. The 12K mark was about what I was guessing, but I've been surprised by things like this before.

CML Service Posted July 13, 2008 Share Posted July 13, 2008 You may be very close to your trailer limits. My B61S tractor full of fuel and wet tank weighs just over 18,000.

GearheadGrrrl Posted July 14, 2008 Share Posted July 14, 2008 I would bet it weights at least 15,000 pounds. Quote Link to comment https://www.bigmacktrucks.com/topic/3985-b61-weight/#findComment-20546 Share on other sites More sharing options...
randyjinla Posted July 14, 2008 Share Posted July 14, 2008 squid, your truck sounds about like mine, the book says a little over 12000lbs. A friend hauled mine on his 53 foot ramp trailer behind a 3500 chevy duramax, almost 400 miles with no problems. i have a pic of it on the trailer in the gallery under randy's b model.

b61fred Posted July 15, 2008 Share Posted July 15, 2008 my mack is very close to the same specs as yours and it weighs 13,600 pounds... b61, thermodyne, duplex, single frame, tandem camelback 38,000, alum. tanks. short wheelbase.Morgan Quote 15 gears...no waiting!

Squid Posted July 16, 2008 Author Share Posted July 16, 2008 Well, I tried loading it today, and it physically fit on the trailer, but I couldnt load it backwards like I wanted to. As soon as the tandems started climbing the ramp, I lost traction. I was able to put it on forward, but that was WAY too much weight on the pickup, so I'll try backwards again here in a few days, this time with a little help from a machine. My goal is to put most of the weight over the trailer axles, and as much as i have to, but as little as possible on the truck.

Ensure you have at least 80 psi in the trailer tires. I've seen many single tire tandem axle trailer tires broken loose from the rim at the bead during a sharp turn. This is of course due to overloading, and you are right at that limit. I've always carried mine engine forward, and about 60% of the weight on the pulling unit by backing the truck as far as possible on the trailer deck.Good luck,Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Squid Posted July 16, 2008 Author Share Posted July 16, 2008 Yeah, the trailer tires are up to 80, max. The way my ramps are configured, it makes it difficult to put anything too far back, but I might have to get creative in this case. I won't move it if I don't trust it, I can probably get a lowboy if I have to, but I'm trying to avoid that situation. I'll give it a shot backwards, and go from there.

I've chained mine so the point straight out the back almost parallel to the ground to provided clearance. If you do something like that, don't rely solely on the clevis hooks of the chains for support. Bolt you chain links together so the don't come apart at an inopportune time.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
