Kobelco large-size SK3500D demolition machines, with a working height of 65.03m, are the largest in the world. These machines were designed to dismantle tall, strong buildings. Kobelco has adopted a new machine structure design which incorporates detachable built-in hydraulic pins. Such pins improve the disassembly and transportation of these large machines. This paper outlines KOBELCO SK3500D and the technologies used in its design.
