Crane girder: 
The crane girder is of welded girder construction. This result in lower dead weight with a high degree of  vertical and horizontal rigidity and small wheel loads being transmitted to the crane runway! 
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 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 & long life. 

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