Dual Speed Diesel
Liebherr RTGs are supplied with a dual speed diesel
engine as standard. Controlled by Liebherr designed
drive systems, the engine switches to idle mode when
full power is not required reducing fuel consumption.
Significant savings on fuel bills are achievable when
compared with traditional RTG power options.
Variable Speed Diesel
A Liebherr variable speed engine delivers optimum
power levels as required while reducing the engine
speed wherever possible. Liebherr’s drive system
ensures precision control over the entire process
resulting in further savings in fuel consumption.
Diesel Electric Hybrid
Fitted with an energy storage solution, this option offers
substantial savings without any loss in productivity.
Using stored power from the reserve when ever possible,
the reduced dependability on the diesel engine typically
delivers fuel savings of up to 40% dependent on
operation.
Full Electric
A full electric RTG from Liebherr delivers many
benefits. Reduced maintenance and lubrication costs
resulting in substantial savings, with a considerable
reduction in energy costs and the elimination of engine
noise and emissions. RTGs can be factory fitted for
electric operation or an E-RTG solution can be retro
fitted. Power regeneration on the RTG to the grid also
means that energy costs are further reduced. Options
include a cable reeling drum or conductor bar system.
Electric RTGs can be fitted with an auxiliary generator
or connection for a portable generator to allow
movement between the stacks.
