ROTARY TROLLEY OF A CONTAINER CRANE FOR CHANGING THE DIRECTION OF A TRAILER

摘要

PURPOSE: A rotary trolley of a container crane is provided to rotate a container at 180 degrees by moving back and forth and rotating the trolley and to position a door of the container at which freights are easily checked, in loading the container on a train. CONSTITUTION: A rotary trolley of a container crane is composed of a main frame(10) moving longitudinally along a rail(2) separated from a girder(5) at the predetermined height; a lift mechanism assembly(20) installed rotatively in the center of the main frame to lift up a container; a ring-shaped circular frame(15) formed in the center of the main frame; an orbiting rail(16) disposed on the circular frame along the circumference; an orbiting wheel(41) installed under the lift mechanism assembly and placed on the orbiting rail; and a motor(42) for rotating the orbiting wheel.
