Howell Abduction-Load Research Test Device precisely demonstrates & calibrates ACL-friendly Howell SkiBindings.
Includes:
6-foot by 6-foot by 2-inch stainless-steel test-frame. All frame components are to be assembled by purchaser using the supplied stainless-steel brackets and stainless steel bolts that are supplied. All assembly holes are pre-drilled.
High-strength applied-force sailing-line, plus 3-to-1 ratio yacht-racing block / pulley.
Applied-abduction-force transducer range: 1 to 350-pounds, with over-load limiter.
Electronic signal-conditioning (with automatic temperature balancing) and digital peak-load display;
Applied-abduction-force ski-clamp hardware;
Released-ski preventer-hardware & rigging (requires minimum 18-foot ceiling);
Stainless-steel boot-holding fixture and rigging (rigidly fixes any ski-boot — alpine, AT, telemark);
6 certified 25-pound calibration weights (each shipped separately);
Biomechanical ACL-rupture threshold data.
Does not include ski, boot, or binding.
3 wooden shipping crates: 1 electronics; 1 calibration weights; 1 the balance. All 3 crates have the goods internally-wrapped in plastic to mitigate water-intrusion.
Available now for 60-day delivery.
FOB Granby, Québec, Canada.

☄️ Special note to scientists currently practicing ‘normal science’ pertaining to skiing-ACL research —
Independent-validation of the biomechanics behind Howell SkiBindings may be useful for those who seek to reach beyond ‘normal science’ — to explore the interrelationship between ski-binding function and surrogate ACL, MCL, meniscus and tibial-plateau integrity / failure.
Normal science in ski-binding biomechanical research measures tibia-biomechanics — resultant torsional-tibia-torques and resultant forward-bending-tibial-moments arising from abduction-force applied to the front-third and rear-third of a ski.
Ski-binding related biomechanical research that reaches beyond normal science to investigate ACL, MCL, meniscus, and tibial-plateau biomechanics — extraordinary science — includes the additional measurement of (1) the magnitude of the applied-abduction-force, (2) the magnitude of the resultant abduction-moments, and (3) the applied-abduction force located at all positions along the full-length of a ski — especially the middle-third of the ski. This special research test device reaches beyond normal science to provide the exploration of extraordinary science.
