Truck Crane A7-1 (55t)

Truck Crane A7-1 The truck crane adopts self-made special-purpose chassis with 8× 4 drive. The ergonomic streamline semi-mounted driver's cab with double wing door, which has obtained a national patent, makes it convenient for rear rider to get on/off cab. The crane adopts WEICHAI Steyr engine which is specially developed for those cranes that often travel at low speed. This kind of engine not only can produce large output torque when it starts and increase the traveling speed quickly, but also has excellent starting performance and good gradeability. The crane is equipped with 9-speed gearbox which changes gear smoothly and is of simple structure and makes maintenance convenient.Item Value Remarks Working performance specification Max. rated total lifting capacity kg 55000 Max. load moment of basic boom kN.m 1764 1470 (Outrigger beam half extended) Max. load moment with max. main boom length kN.m 940.8 793.8(Outrigger beam half extended) Max. lifting height of basic boom m 11.6 Max. lifting height of main boom m 42.1 Deformation of boom is not taken into consideration Max. lifting height of fly jib m 58.3 Working speed Max. speed of single rope on main winch m/min 130 The 4 th layer of drum Max. speed of single rope onauxiliary winch m/min 72 The 2 nd layer of drum Derricking time of boom s 50 Telescopic time of boom s 95 Slewing speed r/min 0-2 Traveling specification Max. traveling speed km/h 76 Max. gradeability % 32 Min. turning circle diameter m 24 Min. ground clearance mm 260 Limits for exhaust pollutants and smoke Comply with related standards GB3847-2005GB17691-2005(Stage III) Oil consumption per hundred kilometers L 40 Mass specification Deadweight of crane in traveling condition kg 40400 Complete vehicle kerb mass kg 40200 Front axle load kg 14900 Rear axle load kg 25500 Dimension specification Overall dimensions(L×W×H) mm 13300×2750×3550 Base on outriggers m 5.92 Distance between outriggers m full extended 6.90half extended 4.70 Main boom length m 11.1-42.0 Main boom angle° -2-80 Fly jib length m 9.5, 16 Offset angle of fly jib ° 0 , 30 Chassis Model ZLJ5401 Class II Engine Model WP10.336 Rated power kW/r/min 247/2200 Max. output torque N.m/r/min 1250/1200-1600
