Wow, that gives me 686,400lbs!!Count the tires multiply 650 lbs per an inch in width of approximately 11 inch wide tires and that will give you the weight capacity.
Looks like it would hold refinery parts such as cooling towers and etc, a transformer transport trailer would be lower slung down for height and they can weigh around that weight too.Wow, that gives me 686,400lbs!!
Wish I'd seen the load.
