700t Segmental Launching Gantry Crane for Highway & Railway Construction

700t Segmental Launching Gantry Crane for Highway & Railway Construction  Product Description          Segmental Method with a Segmental Launching Gantry (LG) is a very popular way used for the construction of bridges and viaducts with small curve and long span.      Segmental Launching Gantries are used for erecting Precast Segmental Bridges and it uses Balance Cantilever Method or Span by Span Method. Launching Gantry can be designed as Underslung or Overhead Model to meet the site requirements.   Whenever Segmental Launching Gantry is use, efficiency is crucial. NANTE Heavy Industry Launching Gantries are designed to save every single minute in the construction sequence. Motorized mechanisms are used for continuous self-launching, electric winches with motorized travelling wagons are used for segment lifting and transporting, Spreader Beam with 360° on plane rotating, vertical tilting and angle adjustment functions are provided.-------------------------------------------------------------Design and manufacturing features------------------------------------------------------------Our glue-as-you-go procedure is a special erection method for glued span-by-span bridges. A stiff main girder allows limited pre-loading of the LG, avoiding time consuming double handling.A symmetrical system allows turnaround of the LG without dismantling and re-erection. A special gantry crane, able to travel over hinges, combined with a 360 degree horizontal bearing on the bottom block, allows very flexible and smooth segment installation.Tower elements placed below the support beams allow substantial changes in the longitudinal slope. This facilitates compensation or elevation differences between neighboring bridges and repositioning of the LG in a vertical direction by vertical climbing of the LG.Easy extension of the support beam for overhead Launching Gantries makes sideways movement of the whole system to the neighboring bridge or over existing superstructures possible. Product ParametersItemsLifting MechanismItemTraveling MehanismHook Rotation MechanismMain Leg Reverse Roller Bottom Leg Reverse RollerCapacity(t)60Traveling Speed (m/min)0~10(Inverter)0.42r/min0~3(Inverter)3.47Work DutyWhole MachineA3Lifting Mechanism M3Work DutyM3Lifting Height(m)28Operating Air Pressure(kgf/m2)≤25Lifting Speed(m/min)0~2(Heavy Load)0~4(No load)Power Supply3P 380V 50HzPower Supply3P 380V 50HzRail Model80×40-H BeamH BeamWire Rope Φ×LengthΦ20×375mWheel Φ360-240240Max kn×Reeving5t×(6+6)Wheel Pressure (KN)210-15025MotorModelYZP200L2-6MotorModelYZPEJ90L-4YEJ80M1-4YZPEJ80M2-4YEJ71M1-4Power(KW)30Power(KW)1.50.550.750.25RPM(r/min)980RPM(r/min)1420139013901380Qty.1Qty.42164ReducerModelZQD850-141.73ReducerModelKF77-78.07XLED53-595KF57-90.26KF47-90.86Overall Gear Ratio141.73Overall Gear Ratio203.843343.33350.42299.3Qty.1Moudle & Teeth2m=8,Z1=18 Z2=472/m=6,Z1=21 Z2=11816/m=6,Z1=17 Z2=664/m=6,Z1=17 Z2=56BrakerModelYWZ4300/E80BrakerModel----Torque(N*m)750Braking Torque2010105Pusher ModelEd80/6Pusher Model--- Qty.2Qty.42164Company Profile           FAQQ1: Are you Manufacturer or Trading Company,A1:We are an integrated industrial and trade enterprises.
