The Profile Damper Type TC from the innovative ACE TUBUS Series is a maintenance free, self-contained damping element made from a special Co-Polyester Elastomer. They have been specially developed for Crane equipment applications and fulfill the international Industry standards OSHA and CMAA. Many crane applications require a spring rate with a high return force. This is achieved with the unique Dual- Profile Concept of the TC-S models. For Energy-Management-Systems the TC model types provide a cost effi- cient solution with a high return force capability. The very small and light package size from ø 64 mm up to ø 176 mm covers an energy absorption capacity ranging from 450 Nm up to 12720 Nm/cycle. The excellent resistance to UV, sea- water chemical and microbe attack together with the wide operating tem- perature range from -40°C to 90°C enables a wide range of applications. Life expectancy is extremely high; up to twenty times longer than for urethane dampers, up to ten times longer than rubber buffers and up to five times longer than steel springs. Overload capacity: For emergency use only (1 cycle) it is possible to exceed the W3 rating by +40%. Environment: Resistant to oil, grease, seawater and to microbe or chemical attack. Excellent UV and ozone resist- ance. Material does not absorb water or swell. Dynamic force range: 80 000 N to 978 000 N Temperature range: -40°C to 90°C Energy absorption: 31% to 63 % Material hardness rating: Shore 55D Mounting: in any position Impact velocity range: up to max. 5 m/s Mounting screw torque: M12: 85 Nm M16: 210 Nm On request: special strokes, -characteristics, -spring rates, -sizes and materials. Calculation and selection to be approved by ACE. Mounting Screw One-Piece Profile Body TUBUS-Series Type TC Profile Damper for Crane Equipment Issue 4.2006 Specifications subject to change

Example: With impact energy of 1300 Nm the Energy-Stroke diagram shows that a stroke of about 38 mm is needed. On the Force-Stroke diagram you can estimate the proportion of absorbed energy to rebound energy at this stroke length. Note: with these types the return force towards the end of the stroke is significant and we recommend you try to use a mini- mum of 90% of the total stroke available. Dynamic (v > 0.5 m/s) and static (v <– 0.5 m/s) characteristics of all types are available on request. rebound stroke energy F back Characteristics of Type TC 90-49 450 400 350 300 250 200 150 100 Force - Stroke Characteristic (dynamic) (with impact velocity over 0.5 m/s) Force (kN) F in absorbed energy10 15 20 25 30 35 40 Stroke (mm) Model type TC-SModel type TC TUBUS-Series Type TC Profile Damper for Crane Equipment Issue 4.2006 Specifications subject to change Hub max.
