CARGO HANDLING METHOD FOR CONTAINER CRANE, AND CONTAINER CRANE

摘要

PROBLEM TO BE SOLVED: To reduce fuel consumption and exhaust gas by applying a downsized low-output engine. SOLUTION: A container crane includes a portal crane body 3 having girders 2 at the top; traveling wheels 5 provided at the lower part of the crane body 3; a trolley 6 traversing on the girders 2; and a hanging implement 7 suspended from the trolley 6. A hanging implement winding speed Vmax under a rated load is reduced by a multiple of a ratio tn/tmax of hanging implement lifting load tn under no load to lifting load tmax under rated load based on the hanging implement winding speed Vn under no load.
