Box Type Girder fabricated by weld the MS steel plate. If  girders are of the box section type, the web plates are to be stiffened with full length diaphragms where required and short length diaphragms are to be inserted between the full length diaphragms plates to transmit the trolley wheel load to the web plates of the girders.

Girders shall be calculated in accordance with the most recent edition of IS standards for girders design. A rail of adequate size shall be fastened to the top plate of the girder and provided with wheel stops to prevent trolley over running.

Advantages

• Greater hook height – how far above the floor the hoist will lift
• No limits to maximum span or capacity
• Ideal for production and transportation of heavy equipment
• Ideal for high frequency of loading unloading  of heavy loads
• Easy to add additional features like walkways, maintenance platform, cabs, magnetic reels, light etc.

Dis-advantages

• More expensive due to added material, heavy supporting structure and complex crane component
• More costlier than single girder in terms of installation and freight
• Hook approach is lessened for both trolley and girder travel
• Higher maintenance and operating cost
