Sales ManagerMila Zhang  12 ton hydraulic truck crane QY12D451 with factory priceProduct DescriptionFreatures for 12 ton Truck crane QY12D451 from ChinaThe lifting, variable amplitude, rotary, telescopic and other mechanisms of the product adopt manual proportional control andhydraulic drive, which are characterized by light and flexible operation, stable and reliable operation, stepless speedregulation, etc.In the hydraulic system, safety valve and balance are provided. Safety devices such as valves, hydraulic locks, brake valves,etc., to prevent accidents caused by oil passage overload and avoiding oil pipe rupture.The upper control valve adopts anti-flow saturation technology, and the flow rate is independent of load, ensuring combined actionStability and synchronization.The chassis adopts the ZLJ5260JQZD5 semi-driving three-bridge special chassis produced by our company, and the left-side all-metalflow.The linear cab is novel and unique in appearance and has good aerodynamic characteristics. The internal control mechanism adoptshumanized design and it is equipped with National IV electronically controlled engine. Its control system uses bus technology andhas engine fault self-diagnosis function.Six-speed gearbox, 6×4 drive, hydraulic power steering, light and flexible. The crane is also equipped with various safety devicessuch as torque limiter and height limit device and complete lighting to ensure safe and reliable operation and easy nightoperation.Product Parameters   ItemAmountRemarkPerformance ParameterRated Capacity (kg)12000 Max. load moment of basic boom (kN·m)465.5 Max. load moment of main boom (fully extended) (kN·m)258.7 7Max. lifting height of main boom (m)29.8These parameters do not include deflection of main boom and jibMax. lifting height of jib (m)35.8Working SpeedMax. hoist rope speed (Main winch) m/min98Drum 4th layerMax. hoist rope speed (Auxiliary winch) m/min87 Boom demrricking up time (s)38 Boom demrricking up time (s)53.5 Slewing speed (r/min)2.2 Traveling speedMax. driving speed (km/h)80 Max.
