88 Issue7.2014 Specifications subject to change 88 One-Piece ProfileBody MountingScrew TUBUS-SeriesTypeTR-HDBumper Radial Damping (HeavyDuty Version) The bumpers typeTR-HD from the inno- vativeACE TUBUS series aremaintenance free, ready to install dampingproductsmanu- factured from a co-polyester elastomer. The TUBUSbumpers are loaded radially just like thebasicmodel TR. Compared to thebasic model, however, their solid structural design offers ahigh level of power andenergy absorp- tionwithin aminimumdampingdistance. The twodifferentmaterial strengths allowdifferent damping characteristics tobe targeted. The slightly biconcave structure alsoensures softer force run. The TUBUS TR-HD is suitable for all forms of use, whichdemand ahigh level of protection against impact or collision. Thehigh level of power andenergy absorptionoffers a wide rangeof application, amongst other in agricultural technology and for construction machines e. g. shovels or articulated joints of construction site vehicles. The relevant support power alsodepends on thematerial strength of the chosen shock absorber. The TR-HD serieswasspeciallydeveloped toabsorba maximumof energy with minimumcon- structionheight. Astrokeof 0.47" to1.73" easily covers energy absorptionwithin a range of between2,036 in-lbs and46,095 in-lbs. Thebumper is simply andquicklymounted horizontally aswell as verticallywith the two supplied screws. Thedrill distance for fastening canbe individually adjustedupon request. 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.
