Giant Excavator

Posted by nahets on October 15, 2008

The following is a news article from the Liebherr Group (also view at Equipment Trader) about their new 800 ton mining excavator:

At the MINExpo 2008 in Las Vegas, Liebherr announced the R 9800 Mining Excava-tor. Rated at 800 tons of service weight the R 9800 provides a nominal bucket capacity of 38 to 42 m³ at a material density of 1,8 t/m³. This new flagship of Liebherr mining excavators’ range is targeting bucket loads of 75 tons in both versions, as a backhoe and a shovel execution.

Liebherr is providing for the machine two engine options, two Cummins QSK 60 with a installed power of 1,492 kW / 2,000 hp each or two MTU 12V4000 with a installed power of 1,425 kW / 1,910 hp.

Whilst the backhoe digging envelope and bucket width remain similar to the previous Liebherr flagship, the R 996, the R 9800 in backhoe configuration provides a break out force of 1,840 kN with a digging force of 1,750 kN. In shovel configuration, the machine is achieving crowd forces at ground level of 2,980 kN and breakout forces of 2,350 kN. These values ensure superior digging capabilities even in toughest mining conditions.

The first units of the new flagship are currently in the final stages of factory testing and the first machine is soon due for operation in Australia.

To get an idea of how big this excavator is, keep in mind that most excavators range from just under 2 tons up to over 100 tons. The ones you see on the side of the road probably weigh anywhere from 5-60 tons. In more practical terms, this 800 ton excavator weighs as much as approximately 100 full grown African elephants, or as much as approximately 15 Boeing Jets!

DEUTZ Introduces World’s First Hybrid Power Unit for Construction Equipment

Posted by nahets on June 16, 2008

DUETZ, a leading independent gas and diesel engine manufacturer, has developed a hybrid power unit for heavy equipment. DUETZ claims the new unit has the potential to reduce fuel consumption by up to 30%. The unit is not only designed to reduce fuel costs and consumption, but CO2 emissions as well.

Here are some of the main specs and functions:

  • Mild hybrid drive unit
  • DEUTZ four-cylinder diesel engine, electric motor, lithium-ion battery pack, control unit
  • Electrical system nominal 15kW output, peak capacity at 30kW
  • Start and stop: automatic engine stop during idling phases, automatic engine start in the case of continued operation, the usual starter is omitted.
  • Power boost: in the case the power peaks, the electric unit is cut in.
  • Battery charging: if the diesel engine has excess power, the electric unit can charge the battery while operating as a generator.
  • Recuperation: part of the braking energy is refed into the battery by the electric unit

The new hybrid drive was developed with Heinzmann, a notable manufacturer of engine control systems and long-term DEUTZ partner and supplier. DEUTZ engines are commonly used in excavators, wheel loaders, access platforms, compactors, cranes, crushers, screeners, compressors, lift trucks, tractors, ride-on mowers, chippers, shredders, gensets and other off-highway mobile plant.
