Hitachi Sumitomo in Japan has launched a heavy duty version of its 90 tonne capacity SCX900-2 crawler crane.
The SCX900HD-2 has a 60 m maximum boom and a 272 kW engine for heavy duty application. The front and rear main winches have 28 mm diameter wire rope and 25 tonne line pull. Multiple wet-disc brakes with pressurised oil cooling system also feature. A third winch drum, offering the same specifications as the front and rear winch drums, is also available.
An LCD display panel indicates actual load, rated load, load ratio, working radius, boom angle and engine speed. A voice and display warning are given when the load moment reaches 90% of rated capacity.
The Mitsubishi 6M70-TL engine meets Tier 3 emission regulations for off-road diesel engines in Europe, North America and Japan, the manufacturer said.
The standard machine's list price is JPY 111,000,000 (US$ 1.2 million). Hitachi Sumitomo forecast sales of 20 units a year.
