pneumatic fenders 1, Use compressed air as cushion medium, in case of collision and squeezing, it can deform softly. Interface area is large, counter force is small, it can absorb large energy 2, When ships berth, mostly there are certain angles, charged rubber balls can sufficienty carry on the advantages and realize standter contact 3, Ships may rise or fall with tide moving up &down, charged rubber balls always float and roil, the frictional force is rather small,which may noe damage the ship itself and ball Size D*L(M) Initial pressure(Po) is 0.05Mpa Initial pressure(Po) is 0.08Mpa Height(kg) R(KN) GEA(KJ) Height(kg) R(KN) GEA(KJ) 0.5*1.0 25 64 6 25 83 8 0.6*1.0 32 74 8 32 96 11 0.7*1.5 50 137 17 50 178 24 1.0*1.5 80 182 32 80 235 44 1.0*2.0 100 257 45 125 335 63 1.2*2.0 120 297 63 165 386 86 1.35*2.5 165 427 102 226 554 140 1.5*3.0 315 597 153 370 751 211 1.7*3.0 405 639 191 436 860 263 2.0*3.5 590 875 308 632 1138 424 2.5*4.0 1050 1381 663 1110 1815 925 2.5*5.5 1333 2019 943 1410 2653 1317 3.0*5.0 1880 2104 1210 2155 2709 1571 3.0*6.0 2160 2583 1485 2470 3292 1888 3.3*4.5 2020 1884 1175 2300 2476 1640 3.3*6.0 2300 2783 1675 2600 3652 2338 3.3*6.5 2700 3015 1814 3080 3961 2532
