Hello, I am new to heavy haul. I currently am helping a forestry company out with low-bedding forestry equipment here in BC, Canada. I've found it hard for anyone to give you a chance at heavy haul if you have no experience doing it. But luckily I have found a person to show me the ropes. I'm just currently helping load and unload / tie down the equipment as I do not work for this company.
I have done lots of research on rules and regs for my province but still find it very confusing. I am overall new to heavy haul and I'm trying to understand placing weight over axles and understanding how many axles you need in order to safely transport your equipment down the highways. I want to understand how to do things legally and proper to not jeopardize safety and be compliant.
We are driving in a peterbuilt 389 heavy haul spec tandem axle with a ASPEN t-series 55 ton triaxle ironhorse. They also have a single axle jeep and a single axle booster if needed.
My main question is, how do I know i can haul a piece of equipment and be legal to do so and how many axles I'm going to need to add in order to achieve hauling a bigger piece of equipment.
We mostly run the setup with no jeep or booster. So if that's 7 axles how much can we haul legally?
I understand there is a lot of calculations to be made based on your setup and state/province you are in. I am looking for a beginners guide or some answers above, or a rough idea as I really enjoy this type of work and want to get more involved in heavy haul.
Weight and permits are my biggest confusion. I am using this CVSE BC website
https://www2.gov.bc.ca/gov/content/...ion-education/commercial-transport-procedures
(additional information)
Examples of equipment being hauled are:
JD skidder 948L - 23 094 kg (50,913 lb.)
JD feller buncher 959M - 37 760 kg (83,260 lb.)
JD loader 2956G - 39 004 kg (85,989 lb.)
New here so thanks again if anyone can be of any help !
any additional information I can provide I will and questions ill be sure to answer back.
New to heavy haul information needed !

@Oxbow your Conrad is knocking your door

As you mentioned, the laws for Oversize and Overweight vary from state to state and province to province. I glanced at the publication that you included, and it appears that studying Chapter 6 closely is going to be the best place to start. It includes bridge formulas and has spacing diagrams to help understand what they are telling you.
Beyond that I would try to get weight information (scale tickets) on the loads that the outfit you are helping is hauling. Finally, take that publication in and sit down with the provincial enforcement folks and go through it. Most of the weigh station folks that have been around awhile will be able to explain the laws to you very well, and they should be happy to do so.
Knowing what a load weighs is obviously crucial, but knowing the center of the weight for that machine is important too, so that you can place the center of the weight where you want it on the deck. One tip for tracked equipment that will give you a fair idea of the center of a machines weight is to pay close attention when loading as to where the track frame is, when the machine breaks over from the ramps to the deck. Other methods for distributing weight include getting to know how air pressure in the suspension relates to weight. That Aspen probably has a chart for the trailer supsension, and you will want to take notice of your tractor air bag pressure and how it corresponds to weight, assuming that you do not have a walking beam trailer.
Really, the guys that are letting you tag along and help are going to be the best at teaching you the ins and outs of what they are doing.
There used to be a fellow on the forum that drove for a heavy haul outfit in B.C.. He no longer participates, but the company that he drove for was good sized and may have an opportunity to learn with them. Problem is I can't pull their name out of my memory, but they had all light blue trucks and trailers, and nice looking equipment.
There are other guys on here with more experience than me. Maybe they will remember the name of that company, and add their insight as to how to learn.
@ElmerFudpucker , @truckdad , @IH Truck Guy , @Rontonio , @stwik , all these guys have more experience than I do. Maybe they can add something.cke, TurkeyCreekJackJohnson, ElmerFudpucker and 2 others Thank this. -
@Oxbow
Thank you so much for your response and your knowledge !cke, ElmerFudpucker and Oxbow Thank this. -
It’s on the tip of my tongue. But I can’t think of it now. Ron will know.
as far as when to use what combo. I can’t really say for certain. There are a lot of factors. But as a broad and I do mean broad statement. Up to 60-65,000 6 axle is fine. 80-85,000 is 7 axles. And up to about 102 is 8. These weights may be higher or lower depending on equipment weight and axle weight laws. But should keep close. I don’t run Canada so I can’t say definitively. But those are the weights for where I run with my configuration -
Some of this could help too. E.L.D.E.R. - Experienced Lowbed Drivers Essential Rules
Oxbow, cke and ElmerFudpucker Thank this. -

Thanks Beast, that's it

I had in my mind that @heavyhammer ran more Alberta to the states, but I didn't realize that Mr Hamm ran for Triton as well as Mullen.cke Thanks this.
