Need:
Timber sales are increasingly being sold with a fuels reduction component that often includes chipping. Chip vans are typically used to transport material from the sale area. Unfortunately, most forest roads were designed to accommodate traditional west coast-style stinger-steered log trucks, and were not designed with chip trailers in mind. Conventional chip trailers have significant off-tracking problems (increasing with trailer length) as well as decreased ground clearance.

Concept:
Convert conventional stinger-steered log trucks for chip hauling
Utilize standard ISO shipping containers
Separate sub frames (front and rear) to create stinger/reach clearance for rolling dips and curves, as well as allowing the use of various container lengths
Containers available in different lengths (20/40/45/48/53) / heights (8.5 and 9.5), closed and open top

Result: Biomass can be hauled from the woods without realigning forest roads.

Estimated Cost (assume tractor and stinger trailer available):

Basic system (closed top, use dump table)Advanced system
Container$2,500Open-top container$2,500
Blow-in chip door$3,000Side-to-side roll tarp$2,000
Sub frames$5,000Walking floor$24,000
Landing gear$2,000Wet kit (PTO/pump)$2,500
Misc. *$1,500Sub total$31,000
$14,000Total, as-built ~$45,000
* Used 5th wheel, new cups (saucer), plywood, etc.

Desirable tractor features:
Air ride suspension (for deploying landing gear)
Quick-change system (to interchange log bunk and fifth wheel)
Wet kit (to power live floor)

Operating parameters:
Container Volume: 88 cubic yards
Estimated payload: 21-22 tons @80,000 lb
Height: 13 3 (50-state legal)
