What does $13k in aluminum build

My son runs a lawn care business and wants trucks set up so he can stop using trailers and his employees can quit lifting ramps. So he bought 3 retired Schwans trucks and I built the first bed, finally finished late last night. It's a fairly complex build with a side dump box for clippings and leaves, a bed with beaver tail, and hydraulic lift ramp. This is what it looked like to start. Lol

That is over $9000 in aluminum, a slight miss calculation meant another trip for over $3,000 more later to total over $13,000.00 just in aluminum. The front is a side dump box, 8' wide and 6' deep. The sub frame was pretty complex because it had to be flexible to twist with the truck frame, but rigid enough to keep the box from flopping around. I think I got it done, we will see if it holds up.

The box was next. He wanted it with short sides so it doesn't catch so much wind when driving when they are not using it, and with fold up sides for more space when in use.

The bed was also a bit more complex than average as he needed it low for loading and 11' long so he can haul his big tractor for leaf cleanup and 2 zero turn mowers for mowing. That meant dropping the main rails down between the truck frame to get the slope we needed.

Figuring out the ramp lift took some serious pondering. I basically copied some designs from farm machinery I've seen over the years, but even then it took some trial and error.

Here are a couple videos of the ramp. I have since put a restrictor in the line so it moves slower.



Thats all I can post at one time, I'll add more later.
 
Unknown if you are one to tolerate constructive criticism. Looks like Low clearance, bed to rears, even light. Best case , precludes larger tires or all but lightest equipment. If possible that business expands to heavy land scape or light construction, may prove wise to start with 5 ton class truck and build with proper steel.
Don’t know if these will see winter use or not, but aluminum is the proper material for truck beds in Minnesnowta.
 
Going to nerd to drill some holes in those ramp channels or they will fill up with water on you. Lots of welds there.

Great work! Ron MN
 
Go it. Minnesota. Low tire clearance, rated but for large mowers, just send it. No worries.
I dont see how you find tire clearance issues, I set 1" more above tire clearance than space between the axle and frame stop. Also, the heaviest mower he will load is this jd at about 2,000 lbs as is or 2-1200lb zero turn mowers. I tested it with a 4500 lb tractor to check for weakness. Why would he want a military truck to haul lawn mowers?

This isn't Jon's first rodeo.

Nice work.

Did you use a spool gun?
 
I never suggested a true military truck, but one may demonstrate adequate capacity and tire clearance. Your Minnnisota application fight. One inch tire clearance, best case, measured, untested, offers little clearance in real world, let alone for bigger tires, chains, et cetera. Constructive criticism offered. Some enterprises expand, succeed. Best to build in capacity for growth. You rigged up a fine, shinny, little commercial mowing rig.
On the tire clearance, if you loaded a D8 cat on that bed and compressed the suspension so it was bottomed out on the axle, you would still have 1" clearance above the tires. There is no way that bed can touch the tires. And as to larger tires, he spent a fortune to get that bed as low as possible, so larger tires is not in his future. Right now there is about 6" of clearance. That is an F550 with an 18,000lb load rating. If he can get 5,000lbs of grass in the box and 3,000lbs of mowers on the back, he hase some reserve capacity.
