    Understanding Overhead Crane Deflection and Criteria – Spanco

    For Spanco, this number is, as specified above, L/600. A gantry crane spanning 300 inches has a deflection of a half an inch (.5 inches). To determine the deflection for a jib crane, the equation remains the same, but the terminology can also differ from system to system, and the deflection limits differ once again.

    How Much Weight Can They Lift? – How Tower Cranes Work

    The maximum load that the crane can lift is 18 metric tons (39,690 pounds), but the crane cannot lift that much weight if the load is positioned at the end of the jib. The closer the load is positioned to the mast, the more weight the crane can lift safely.

    The largest capacity overhead cranes are top-running, double-girder cranes. Traveling on top of two parallel girders, these cranes offer maximum headroom and lifting height, carrying capacities upward of 600 tons. For hard-to-reach applications, monorail overhead lifting systems can be installed directly
