Product Description High Safety Electric Control Cranes Cargo Lifting Equipment Double Beam Overhead Bridge Crane for WarehouseProduct DescriptionA double girder overhead crane is a heavy-duty lifting system designed for demanding industrial environments where high lifting capacities, extended spans, and precise load handling are critical. With two parallel main girders supported by end trucks, this crane type offers superior strength, stability, and versatility compared to single girder designs, making it ideal for heavy industries and large-scale operations.Vantage1: Structural Design: - Two robust main girders (box-type, truss, or fabricated profiles) provide exceptional rigidity, minimizing deflection under heavy loads. - Higher hook height due to the hoist being mounted *above* the girders, maximizing vertical workspace. - Suitable for spans exceeding **30 meters** and capacities ranging from **5 tons to 500+ tons**. Vantage2: Hoisting Mechanism: - Equipped with heavy-duty wire rope or chain hoists (e.g, Konecranes, or ABUS) for lifting extreme loads. - Optional auxiliary hoists for secondary lifting tasks (e.g., maintenance or lighter loads). Vantage3: Driving System: - Dual-drive motors on bridge and trolley ensure smooth, synchronized movement even with uneven loads. - Advanced frequency-controlled drives enable precise positioning and reduced wear. Vantage4: Control & Safety - Multiple control options: pendant, radio remote, cabin-operated, or fully automated systems. - Integrated safety features: overload protection, anti-collision systems, emergency stops, and redundant braking. Application1.Manufacturing Facilities: Ideal for lifting and moving heavy materials in manufacturing plants, assembly lines, and workshops.2.Warehousing and Logistics: Efficiently handles loading and unloading tasks in warehouses, distribution centers, and logistics facilities.3.Construction Sites: Provides reliable lifting support for construction materials and equipment on construction sites.4.Power Plants: Essential for maintenance and installation tasks in power generation facilities such as thermal power plants and hydroelectric dams.5.Shipbuilding and Ports: Used for lifting and transporting heavy components in shipyards and port terminals.Detailed PhotosDetails showProduct ParametersCapacity Unit3.2T5T10T12.5T16/3.2T20/5T25/5T32/5T40/10T50/10T63/12.5T75/20T80/20TSpanm10-40Lifting heightm6-40Power supplyV220v,240v,380v,400v,415v,440v,460v,480v,525v/3p/50HZ,60HZwork class A3,A4,A5,A7 or as customer requirementControl voltageV24v,36v,48v,110v,220vLifting speedm/min5/0.8dual5/0.8dual5/0.8dual5/0.8dual5/0.8dual5/0.8dual4/0.67dual4/0.67dual4/0.67dual4/0.67dual3.2/0.5dual3.2/0.5dual3.2/0.5dualTrolley Speedm/min20/5 Frequency conversion dual speedLong travel speedm/min30/10 Frequency conversion dual speedLifting motorKW3.2/0.456/19.5/1.512.5/216/2.620/520/520/523/3.52*18.5/32*18.5/32*23/3.52*23/3.5Trolley motorKW1*0.371*0.551*1.11*1.12*0.552*0.752*0.752*1.12*1.12*2.22*2.22*2.22*2.2Long travel motorKW2*1.52*2.22*32*32*32*32*32*32*42*5.52*5.52*7.52*7.5Crane powerKW4.31-6.677.38-11.0411.95-16.4515.8-20.719.3-23.523.7-27.523.7-27.524.1-28.229.6-33.247.5-52.447.4-52.458.4-65.458.4-65.4Electrical parts brand SchneiderControl model Pendent control, Remote controlfestoon system type C track with flat cableRecommended crane rail 50*3060*4070*4080*40100*40120*50IP/Isulation class IP55/F class is default,IP65,IP66 and H class is optionalBrake Type electro-magnetic brakeMax wheel load KN31.3-7839.6-87.869-119.682.3-131.552.5-84.352.5-84.375.4-110.075.4-110112.7-151.8145.6-185167.8-221.3167.8-221.3208.7-367.3Total weight t4.5-23.25.15-23.56.9-26.77.3-26.757.8-30.57.8-30.59.2-33.459.2-33.4511.75-38.513-42.9513.95-48.113.95-48.117.05-52.55Trolley weightt0.460.37-0.381.081.081.47-2.391.47-2.392.21-2.782.21-2.782.76-3.094.1-4.44.51-4.524.51-4.525.29-5.39Safety protection Function security monitoring system,Overload protection, Hoisting overheat protection, Warning Horn and Falsh,Low voltage protection,over current protection, up&down position limit switch,cross limit switch,Door interlock limitsWorkshop Certifications Our ServiceChunhua have a professinal team which have about 30years experience to produce crane and crane components.Chunhua have professinal team for crane Installation and CommissioningChunhua provide 2 years long term warrantyChunhua will response to customer request with 24 hoursFAQQ1: Are you Manufacturer or Trading Company?A:We are an manufacturer.
