The TR31 Tight Radius rail and trolley system is designed to work as a movable anchor point for fall restraint applications. It allows a crew member, fully harnessed and securely tethered to the trolley, to move freely along the rail during inspection and maintenance, or when assisting in pilot transfer. Systems are composed of straight and curved rail sections that change direction in both horizontal and vertical planes, allowing trolleys to run exceptionally smoothly past very tight radii and joints. The Harken Industrial TR31 system is independently tested and is compliant with EN795:2012 Type D. It also meets ANSI Z359 and is OSHA compliant.
