What kind of truck can carry 61,500lbs?
I drive a fairly large concrete mixer that has a nominal max payload of 11 cubic yards that is roughly 44,000 lbs.
Anything heavier requires additional axles, they have mixers that are on trailers but they are very very large and are rarely used in most cities.
About the only way to get that kind of weight on a truck is a set of turnpike doubles. Or a multiple axle lowboy trailer.
Wheeled Tank transporters have been around for a long time. the WWII medium tank was the Sherman weighing 34 tons or 68,000 pounds. They were hauled on multiple axled trailers for long distances to save wear on the tank’s tracks and suspension. Newer transporters routinely haul tanks weighing 52 tons and more. Check out this link
On dirt and sand roads yet....That sucker would sink plumb up to his eyeballs.!!
