Iron Monster Bridge Builder Machine China
Ever wonder how some countries build those massive bridges? In China, they use the SLJ900/32, which received the nickname “The Iron Monster,” and rightfully so. Developed by the Beijing Wowjoint Machinery Company, this massive machine is capable of carrying, lifting / placing sections of track, and connecting pillars with heavy stone blocks. Once each section is laid, the 300-foot vehicle with 64-wheels returns to collect another block before rolling forward to place another section.

Even transporting a full load of materials, it moves at a steady 3mph, which means it’s still fast quicker than traditional building methods that require large cranes to be erected on the ground. So far, it has worked on several high-speed rail projects, including the link between Inner Mongolia and the rest of the country, which is no surprise since each of the sections can rotate up to 90&deg, allowing the machine drive sideways for efficiency when picking up beams.

Launching machines are always customized to suit the specific bridge design, construction conditions, structural dimensions of beams and so on. Even if a bridge project needs multiple launching machines, the supplier may design different erection solutions and the launching machines may vary in structure, operation and controls,” said Yabin Liu and Fuchun Yuan of the Beijing Wowjoint Machinery Co.
