The 1,100-ton double-girder gantry crane independently researched and designed by China was successfully manufactured by China Railway Baoqiao Co., Ltd. a few days ago. This is currently China's largest portal lifting equipment, known as "China's first crane."
China Railway Baoqiao Co., Ltd. has developed a 1,100-ton gantry crane. The entire crane adopts the current internationally popular double-beam and four-legged steel box girder structures, and uses nearly 600 tons of steel for construction. For the double-car split mode, the main and auxiliary trolleys can lift up to 1100 tons. The hooks adopt stacking double hooks and can rotate 360 ​​degrees. The main beam adopts eccentric rail box beams, and the internal parts of the beams require convenient access. All the legs are rigid legs, and the main beam and the main force members are made of the new high-quality materials rarely used in the domestic steel structure manufacturing. The large and small cars and the main hook use the variable frequency speed control system and use the matched motors. This is in China. It is the first time in the production of gantry cranes. This machine adopts well-known manufacturers' products in the selection of other devices to ensure the product quality performance and become the "first" product in the real sense.
Experts believe that the completion of the 1,100-ton crane marks a breakthrough in the development and design of large-scale lifting machinery equipment in China, and has created conditions for China to enter the international lifting machinery manufacturing industry.
