90 Issue7.2014 Specifications subject to change 90 One-Piece ProfileBody MountingScrew TUBUS-SeriesTypeTCBumper For Crane Equipment The bumper typeTC from the innovative ACE TUBUS series is amaintenance-free, self-containeddampingproductmade from a special Co-Polyester Elastomer. They have been specially developed for craneequip- ment applications and fulfill the international industry standardsOSHA andCMAA.Many crane applications require a spring ratewith a high return force. This is achievedwith the unique Dual-ProfileConcept of the TC-S models. For energy-management-systems the TCmodel types provide a cost efficient solution withahigh return forcecapability. The verysmall and light package size from Ø 2.52" up to Ø 6.93" covers anenergy absorption capacity ranging from3,983 in-lbsup to157,632 in-lbs/ cycle. Theexcellent resistance toUV, seawater, chemical andmicrobe attack together with the wideoperating temperature range from -40 °F to120 °Fenables awide rangeof applications. Lifeexpectancy is extremely high; up to twenty times longer thanurethanedampers, up to ten times longer than rubber bumpers andup to five times longer than steel springs.
