@shandongboss001: You probably didn't know this. Tower cranes don't get taller with another crane. They grow by themselves. Using a hydraulic climbing system, the crane lifts its own upper structure, creating space for a new mast section to be inserted underneath. The process is then repeated until it reaches its final height. One section at a time. That's how tower cranes grow. Follow me—not only to see my company, our daily work, and the industrial projects we're building, but also to discover the side of China that most people never get to see. #towercrane #construction #engineering #machinery #china
