Development

Universal Track Unit
	; Short description
Specifications
Product Ecology	To be built with the D3D CNC Torch Table
License	OSHWA and OSI compliant. CC-BY-SA-4.0 International, GPLv3, DIN SPEC 3105.
Motor	Can use a small hydraulic motor with 3-4 geardown.
Track Tensioners	2 Identical track tensioners tensions motor and track independently
Key Specification	Scalable to multiple motors, different geardown ratios, and capable of being stacked in dually configuration. Maximum design drive is 13,000 lb potential drawbar pull per track unit.
Key Specification	Drive system applicable to traction machines with each track unit ranging from 1400 lb at 4 mph and 10 gpm (20 hp) at 3x geardown, to 1400 lb and 8 mph at 20 gpm (40 hp) and single motor, to 2800 lb at 4 mph and 20 gpm with dual drive motor (40 hp), to 5600 lb power operation with dual motors at 40 gpm at 4 mph (80 hp) and 6x geardown.
Construction	CNC cut steel, stock steel, and off-the-shelf bearings + motors.
Productivity	Practical range from 10-80 hp per drive unit using the same parts, for applications from small walk-behind tractors to small bulldozers.
Completion Status
