In the autumn of 2013, N.C. Nielsen, Denmark's leading supplier of heavy duty machinery, unveiled a customised SMV Konecranes reachstacker with double lifting capacity of 100 tons. This was an unprecedented machine type on the market. The development process started with a query from a harbour terminal in Aarhus that needed a manoeuvrable machine to ship the increasingly heavier offshore turbine elements. The process was concluded when N.C. Nielsen delivered a customised 100 tons prototype based on a heavily modified SMV Konecranes reachstacker for the harbour in Aarhus.
Interest in the new heavy duty reachstacker is large, in Denmark and abroad. The demand has resulted in a unique collaboration between N.C. Nielsen and Konecranes Lifttruck: The Swedish machine manufacturer will deliver brand new SMV Konecranes reach stackers with the 9 metre wheelbase required while N.C. Nielsen will handle the remaining structure of the special version.
The capacity has been doubled by modifying a classic 45 tons SMV Konecranes reachstacker in various key areas. The original lifting cylinders have been turned 180° to reduce their degree of load, the spreader has been removed and the machine's original twin-mounted drive shaft is now complemented by a newly developed "undercarriage" with 2 x 4 wheels to distribute the weight. One of the crucial changes is the widening of the wheel base from 6.4 to 9 metres. When developing the prototype, the chassis of a second-hand SMV Konecranes reachstacker was cut through and extended at N.C. Nielsen's workshop. The agreement with Konecranes Lifttruck now ensures the manufacture of 100 tons versions with a brand new longer chassis.
