ISO Standard Double Girder Overhead Crane for Steel Mill Workshop

                                         ISO Standard Double Girder Overhead Crane for Steel Mill Workshop   Product DescriptionDouble girder overhead crane with hoist, also known as double girder bridge crane or double girder crane, is the kind of overhead crane specially engineered with stronger double girder to lift and transport heavy loads up to 63 tons across large areas.     Double girder overhead travelling crane is composed of box type welded main girders, double rail lifting trolley with fixed electric hoist, crane traveling mechanism and electrical system, etc. All these overhead crane components are designed and optimized with continuously rigorous functionality, high performance and safety operation by NANTE experienced professional team.     NANTE brand double girder bridge crane features custom modular design, integrated manufacturing, customized construction, safe and flexible operation, etc. Our double girder crane can be designed for work duty as A4, A5, A6 and integrated into different building structures by our customized girder connection parts, it is the ideal material lifting and transporting equipment for Medium heavy duty applications with longer span.------------------------------------------------------------------Design and manufacturing features--------------------------------------------------------Design Code: NANTE's Single Girder Low headroom overhead crane follows the design code of FEM, CMAA, ISO EN, BS, GB standard. Double Girder Hoist: Low head room design, compact structure, smooth operation, accurate positioning, high Safety reliability, and Maintenance-friendly.Girder: Compact Design and low weight, use Q355B steel material(ISO EN S355, DIN ST52, ASTM A 572 Grade 50), welding specification follows ISO 15614, AWS D14.1, deflection can from 1/700 ~ 1/1000, MT or PT is requested for Fillet welding and UT is requested for joint welding. End Carriage: Direct Driving design with high transmission efficiency. Using hollow tube for the steel housing. Wheel material is alloy steel with proper heat treatment which is more stable and durable.    Gear Motor:Worldwide top brand gear motor to make sure the quality, IP55, F insulation class, overheat protection, manual release bar, and equipped with electro-magnetic brake.Control Panel:Follow IEC standard, IP55 powder coating high quality enclosure, socket plug-in for easy connection, DIN standard terminal, international brand for the inverter, MCB, Contact and electrical devices on the panelFestoon System:Double line Galvanized C track system or I beam with flexible flat cable, one line for hoist power and signal transmission, one line for the pendent control trolley movement. No-welding claw is design for the brackets of the festoon system fixing. Safety Protection Functions:NANTE Double girder overhead crane include a lot of protection functions, like Overheat protection for the lifting, load cell type overload limit switch, up&down position limit switch, cross limit switch for the cross travel and long travel. Phase sequence relay, and other optional functions, like crane monitoring system, LED load displayer. Controls:NANTE Double girder overhead crane can offer remote control, pendent control and crane cabin control. Anti-corrosive Treatment:Shoot Blasting follow ISO8501-1 SA2.5 class, roughness follow ISO 8503 G class, clearness follow 8502-3 Level II. Use top brand's Rich zinc epoxy painting for the prime, middle layer coating. Use polyurethane topcoat for the finished layer coating. All NANTE painters are trained or inspected by NACE or FROSIO level II InspectorApplications:Double girder crane is the ideal material handling equipment for wide span medium, heavier-duty applications such as mechanic processing workshop, subsidiary workshop of metallurgical mills, warehouse, goods yard and power station, etc. It is widely used in such fields as Pre Engineered Steel Building, Steel Plant, Steel Product Maker, Oil Industry, Plastic Plant, Cement Plant, Power Plant , Mine Industry, Food Industry, Chemical Industry, Cable Plant, Machine Tools, Car/Truck Industry, Transport Company, Construction Company, Electrical Company, Shipyard, Stone Yard, Installation and Maintenance, etc.Product Parameters Technical Data of Double Girder Overhead Crane with HoistCapacity5t10t16t20t25t32t40t50t63tDuty Group(ISO/FEM)M5/2mM5/2mM5/2mM5/2mM5/2mM5/2mM5/2mM5/2mM4/1AmSpanm10~40Height of Liftingm6~40Power220v, 240,380v,400v,415v, 440v,460v,480v,525v / 3P / 50hz, 60hzControl Voltage24v, 36v, 48v, 110v, 220vLifting Speedm/min5/0.85/0.84/0.64/0.62.8/0.53.2/0.72.8/0.60.7~3.30.7~3.3Trolley Speed5/20  (Inverter Control)Long Travel Speed5/20,  8/32, 10/40, 15/60, 20/80 (Inverter Control)Lifting MotorkW6.19.51515189.5/1.5224040Trolley Motor0.37x20.37x20.95x20.95x21.1x21.5x21.5x22.2x23x2Long Travel Motor0.55~1.1kw × 20.75~2.2kw × 20.75~1.5kw × 41.5~2.2kw × 4Model of HoistNHA-D Low Head Room Double Girder Hoist(Double Lifting Speed is defualt, Inverter contro
