Modular Gantry Cranes: Flexible Factory Layout Solutions

The marine gantry crane is a heavy-duty lifting system specifically engineered for the harsh, corrosive environments of shipyards, dry docks, and ports. Unlike standard industrial cranes, a marine gantry crane must withstand constant exposure to saltwater, humidity, and extreme weather while handling incredibly heavy loads such as hull sections, propulsion systems, and shipping containers. These cranes feature massive load capacities, ranging from 100 to 2000 tons, with spans reaching up to 185 meters to cover the entire beam of the largest vessels. The gantry structure is composed of rigid and flexible outriggers with box-type welded main beams, providing high wind resistance and stability. The lifting mechanism uses advanced frequency conversion drives to achieve millimeter-precision control when turning over massive hull blocks or installing sensitive marine engineering equipment. In a typical shipyard, these cranes run on rails embedded in the quay, covering the entire dock area to enhance construction efficiency. Aluminum marine gantry cranes are also available for lighter work, such as moving boats for maintenance in marinas, offering corrosion resistance and portability.
