1. Our efforts to transform thinking about transporting equipment have resulted in greater efficiency in every possible area. We designed the CKS series, BMS series, 7000S series to require less work and to be easier to transport, and to ensure safety during assembly and disassembly. What's more, simpler, more efficient loading for transport have reduced the cost of both transport and storage.
  2. Thanks to superbly rigid construction, and the use of high quality high tensile steel plate, we have been able to create a Upper Frame and body much lighter than other vehicles in the same class, with a greatly reduced width. Not only is assembly and disassembly more efficient, the CKS series, BMS series, 7000S series is easier to transport than any previous system.
  3. The self-removal device of the CKS series, mean that the crawler, carbody weight, and counterweight boom can be assembled and disassembled without the assistance of another crane.
