Heavy Load Double Girder Gantry Crane with Cantilever and 3 Control Methods

Model Number: MG - SGY-H Brand Name: KUANGYUAN Key Specifications/Special Features: Introduction of gantry crane:Design, features and specifications: double girder cranes are used when heavy loads, wide spans or high working frequency are required than single girder gantry craneDouble girder gantry cranes consist of two torsion-free box girders and four legs to achieve perfect construction stabilityThis makes double girder gantry cranes especially suitable for lifting and transporting loads over 10T and for span of more than 25m, load capacities up to 100T and with spans up to 50MThe profiles of the main girder are optimally produced using a integrated technology which is weld-less, so that maximum performance with a minimum of deadweight can be achieved

Standard features of gantry crane:

• Motors: motors are used specially crane duty suitable for frequent starting, reversing and braking in accordance with ISO 9001:2000 ISO 14001:2004
• Motors are totally enclosed in dust-proof construction foot-/flange-mounted TESC/TEFC, Sq cage motors with integrated safety brakes, insulation class F, IP54 protection for hoisting, CT and LT motions
• Brakes: independent hydraulic brake make the crane more safe and easier to control
• Gear box: the entire gear boxes are made of accurate hob cut helical/spur gears and pinions having hardness 250 to 350BHN made from carbon alloy steel
• All gears and pinions running on anti-friction type ball/roller bearings in totally enclosed oil bath giving constant splash lubrication
• The helical/spur gear designed for adequate strength and optimum wear resistance for smooth operation and long lifespan
• Wheels: wheels of crane crab ,main beam and end carriage are produced in our special
• Vacuum casting workshop (no sand inclusion technique) which makes our wheels more elastic and outer surface hard-wearing and durable
• Electrical panel: modular design, ease to install and maintain, reliable operation, fuse less circuitry, ducted wiring and compact terminals
• Motor overload protection to prevent overloading
