We designed and manufactured two sets of 450-ton rail mounted gantry crane for Ssangyong Engineering & Construction Co., Ltd. of South Korea. The equipment was used in the section 2 to 4 of Honam High Speed Railway project to lift and transfer the box girders with length of 35m, 30m or 25m as well as to load these girders into the girder transporter.
Our 450 ton railway rail mounted gantry crane is capable of completing hoisting, handling and loading of box girders weighing less than 450 tons in the precast yard. It is usually used across the main bridge to load girders into the girder transporter on the bridge deck and lift the bridge erecting machine and girder transporting vehicle that are assembled on the ground to the bridge deck. Two sets are adopted for synchronous operations.
In China's high-speed railway construction, when the precast yard is arranged around the bridge, two sets of 450-ton railway rail mounted gantry cranes are used to complete the hoisting and loading of box girders. Our company has produced more than 30 sets of this equipment. They are widely used in the construction of multiple domestic high-speed rail lines.Reference Parameters
