The principle difference between single and double girder cranes is hook height (how far above the floor your hoist will lift). Double girder cranes provide better hook height. Double girders typically allow 18-36 inches higher lift.
Double girder cranes can provide more lift, because the hoist is placed between the cross girders rather than under them. Therefore, the depth of the cross girder is gained in switching to double girders.The advantages of double girder traveling bridge cranes become particularly evident with load capacities over 10 tons, or spans of over 50′. These advantages are:Higher hook lift, since the hook can be pulled up between the main girders.Extremely rigid girder construction and durable trolley design are well suited for heavy service applications.
Double Girder Bridge Cranes are most frequently used where capacities over 10 tons and/or spans of 60 to 100 ft are needed. They can be utilized at any capacity where extremely high hook lift is required because the hook can be pulled up between the girders. Double Girder Bridge Cranes are often used where high speeds and heavy service are required, or where the crane needs to be fitted with walkways, crane lights, cabs, magnet cable reels or other special equipment.
