Help with Long-Term Equipment Setup

People who put that amount of weight on small trailers have problems.
Tires and axel bearings failure.
Then you have to have a truck to pull it.
Then theirs another headache.

 

If you want US based construction contractors to use this system you will need to put them on two trailers. A 30k GVWR trailer will require a CDL-A driver, which is expensive for the contractor. They would likely want to be able to pull these with existing pickup trucks and employees.

In the US, except Washington and California, your trailer can weigh over 10,000 pounds if together with the truck pulling it the total combined weight ratings, and/or actual weight, does not exceed 26,000 pounds. The most common setup like this is a hotshot hauler with 12k trailer and 14k truck.

In CA and WA your trailer alone determines the requirement for a CDL, and anything over 10k trailer weight or rating will require a CDL driver. This will be a problem from a marketing perspective.

Also, as said above, the little trailers have issues with axles and wheel bearings so be sure to select a high quality trailer.

 

I will offer some advice to you, seeing you don't say if you have engineering experience or what you actually do at the company.

GO and find an engineering company that specializes in trailer and equipment design.

Why?

Because there is a huge liability for YOUR company if you put junk on a trailer and it exceeds the operating capacity of that trailer.

You indicated that you could use a bumper pull trailer and anyone in their right mind would tell you that you are not too bright thinking that way. You start with the vehicle that you are going to pull the trailer with that your customers have or you will provide.

But then you gather up the specs, you work a good plan out and you go to an engineering firm with everything for them, work with them and they will make sure you will not kill anyone.

 

Contractors usually do have a number of CDL drivers moving equipment around; why not repackage in an ISO container which could be moved on a Landoll style trailer, as well as flatbed and container chassis.

I'm sure you could get one custom built -or- rebuilt to serve your needs with securable entries and standardized transport dimensions.

The 'after-market' here for re-purposed Iso containers is very diverse so you could get a secure space, possible with HVAC, windows, security etc. to stuff with your equipment once it arrives here.

 

That's pushing it with a bumper pull trailer IMO. You'd be right at the tongue weight limits on most modern dualie pickups.

 

I’m going to be an odd ball of suggesting that you find a “high cube platform container” (flat deck with corner posts to make it stack and liftable as well as compatible for container chassis). Might make it heavier but easier to transport by truck, sea and rail. Can always speck a custom trailer for each customer once you sold them on it.
If the containers are a necessity stick with the common size 20’, 40’. Should be easier to find trailers with attachments for them.

The container being stainless, is it required?

 

Company's along the gulf coast will use a logistics provider to move their rental equiptment.
They don't want the liability.

 

even more reason to re-purpose Iso equipment...

If OP sticks with two units; 20' Iso containers can always be positioned by a carrier with a landol.

Depending on the weight you can locate a 20' box with an automobile roll-back wrecker.

 

What you are describing would really only be able to be pulled by a class 6 vehicle or larger, with a pintle hook. Ball hitches are not legally allowed to pull that kind of weight, and pickups pulling a gooseneck can't really handle that much weight, either. Ideally, something like this would be pulled by a 10 wheel dump with a pintle hook, and the trailer would have a forged loop. This setup would require air brakes, so a CDL of maybe a Class B (but more likely a Class A) would be needed. The regulations for air brakes in the US are NOT the same as European regulations, and any vehicle imported (even trailers) would have to pass USDOT regulations (which are numerous). And trust me, there are literally DOZENS of custom trailer manufacturers here in the US ready to make something just like this for anybody who asks. Furthermore, foreign heavy trucks and truck equipment are rare, due to the "chicken tax" on imported trucks of something like 20%.

I really don't see how your idea could be viable.
