The double girder cranes are used when heavy loads, wide spans or high working frequency are required than single girder gantry crane. Double girder gantry cranes consist of two torsion-free box girders and four legs to achieve perfect construction stability. This makes double girder gantry cranes especially suitable for lifting and transporting loads over 10 T and for span of more than 25m,load capacities up to 500 T and with spans up to 50 M.

The profiles of the main girder are optimally produced using a integrated technology which is weldless , so that maximum performance with a minimum of deadweight can be achieved.

Standard Features:

Motors: The motors are used specially crane duty suitable for frequent starting , reversing & 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 & 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 & pinions having hardness 250 to 350 BHN made from carbon alloy steel. All gears & pinions running on antifriction 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 & long life.

Wheels: The wheels of crane crab ,main beam and end carriage are produced in our special Vacuum casting workshop (No sand inclusion technic) ) which make 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.

Limit Switch: Safety limit switches for stoppers will be provided to prevent over traveling in all motions.

Painting: -Two coats of primer before assembly & two coats of synthetic enamel after testing.

Optional Features :
