This report describes the design and construction of an oversized, ruggedized treadmill built for testing heavy loads. The design permits for speed and slope control, as well as a safety tether and emergency stops. The design description is categorized by related systems. The walking belt is powered by an electric motor, which transfers the mechanical rotation via hubs, a linkage belt and rollers. The floor and surface base are sized and designed for proper operation and clearance. The electronics board provides electric power, speed control, and a powered braking system. Safety features are designed for user protection: guard rails, covers, a gantry crane and tether, and emergency stops. Operation is possible for an incline range of -30° to +30° at 22 increments from the horizontal, and speeds of up to 10 mph with a granularity of 0.01 mph. The larger than usual size and strength allows for extensive usability and testing, for a successful and well-functioning apparatus.
