Configuration around actual operating conditions
A single girder overhead crane can provide a lean system architecture where capacity, span, hook approach and duty are suitable. Headroom and upper hook position must be checked early because the hoist arrangement directly affects available lifting height.
Selection must consider girder deflection, bridge self-weight, wheel loads, runway capacity, travel speeds, cycles, power supply and maintenance access. Double-girder alternatives should be compared for long spans, high duty or critical hook approach.
Final sizing requires verified structural and operating data.
Technical validation
Final capacity, structural loads, duty class, speeds, braking, limits, power supply and site interfaces are confirmed through approved engineering.
