Giant Articulated Tracked Dump Truck
Mike Dunneisen recently sent FARM SHOW photos of a giant, rubber tracked, articulated “dump truck” he built from scratch for his Wisconsin excavating business. The truck measures 37 ft. long and rides on 4 sets of hydrostatically-driven tracks, allowing it to carry a 20-ton load of material. It’s equipped with a lightweight 16-ft. dump box on back and a 60,000-lb. hydraulic winch on front.
The chassis was built completely from scratch with an articulated steering joint at center. The cab is off an old Army tank retriever and the dump box sits on its frame. Dunneisen built the tracks using steel, rubber belting, and UHMW plastic, and attached wooden slats to the tracks for maximum traction.
“We call it the Dragon Wagon and use it mainly in swampy ground where we’re cleaning out ditches or restoring wetlands. An excavator loads dirt into the box and the truck hauls it away,” says Dunneisen. “The tracks cover 22,000 sq. in. of ground and exert less than 4 psi ground pressure even when the truck is fully loaded. As a result, the machine can travel through swamps with 1 1/2 ft. of water without getting stuck.
“I built the machine over a 2-year period, and it has performed even better than we hoped. Over the years we’ve built seven other tracked dump trucks to use in our business, but this one is by far the biggest and most elaborate. We’ve taken it to several shows and are now advertising to find more work for it.”
The rig is powered by a 450 hp. Detroit engine and Allison transmission with a top speed of 30 mph. The engine drives a hydrostatic transmission that independently drives and steers each track.
The front windows of the cab are lined with window tint film that looks like “owl eyes”. “When the truck is driving through tall marsh grass, from a distance all you can see are the eyes which makes it look like a caterpillar is crawling through the marsh,” says Dunneisen.
The dump box was a prototype model purchased from Rowe Truck Equipment, Inc., in Indiana.
