    Foot and Ankle Test System

    Link Engineering Company (LINK) has a long history of designing and developing robust, accurate testing systems. With servo-electric capabilities in-house, LINK has developed the Foot and Ankle Test System using all electric drives, focused on testing foot prosthetics. The system is safe and easy to use, yet flexible enough to accommodate various testing setups. It meets all requirements specified in ISO 22675 and other applicable standards.

    The LINK ISO 22675 Foot and Ankle Test System is based on servo-electric drive technology. The system is a single station, two-axis load frame used for vertical loading and treadle torque/rotation. The actuator chosen for vertical force application is robust, operating under a significant safety factor. It has an easy-to-replace external Duralon-style bearing to protect the actuator from moment loading caused by the ankle treadle rotation.
