In 2002, KOBELCO developed the SK1600D, the world's first building demolition machine with a working height that exceeded 50m. This was followed by the introduction of the 100-ton class SK950DLC and the Guinness award-winning SK3500D, the "world's tallest building demolition machine" with a working height in excess of 63m. Afterwards, we introduced the 100-ton class SK1000DLC and the 200-ton class SK2200D which can be mounted with even larger attachments, maintaining the same working height. Now KOBECLO lineups SK1300DLC, a super-large building demolition machine, available in four configurations, including an ultra-long quad-fold attachment with a maximum working height of 40m.
