A gantry crane for shipping container handling is a specialized piece of port equipment designed to efficiently load, unload, and stack 20ft and 40ft intermodal containers. These cranes come in two primary forms: the massive Ship-to-Shore (STS) gantry that unloads vessels, and the yard gantry (either Rail-Mounted RMG or Rubber-Tired RTG) that stacks containers in the storage yard. The STS gantry features a cantilevered boom that extends over the ship’s hold to grab containers, running on rails along the dock. In the yard, RTG cranes move freely on rubber tires to travel between stacks. When lifting containers, the crane uses a specialized spreader that locks into the corner castings of the container. The gantry crane shipping container system is critical for logistics, capable of stacking containers four or five high to maximize land use.
