Eight Rope Reeving System

• The eight rope reeving arrangement for the hoist
located on the trolley ensures that load sway is
eliminated in hoist, trolley, long travel and skew
directions

• Lower energy consumption

• Superior ne positioning for stack building and truck
loading

• Increase in productivity of between 30 - 40% when
compared to alternative designs

Drive Management System

• Allows simultaneous drive motion for hoist, trolley
and travel

• Increases the machine’s performance

• Reduces fuel consumption

• Optimised for automation

Liebherr Options

• Twinlift 50.8 tonnes/ 65 tonnes

• DGPS automatic gantry steering & container
position recognition, with interface to terminal
operating system.

• Contactless anti-collision system

• Energy chain / festoon

• Remote access to crane management system

Electric Spreader

• Connected directly to the hoist ropes without
a head block thereby reducing tare weight and

providing a more energy efcient operational cycle

with lower fuel consumption

• Single or twinlift execution

• Fixed side guides provided

Liebherr Drive Systems

• Liebherr engineered drive control system for AC
and DC

• Maximum reliability

• Ease of service and repair

• Crane specic modular design

• High quality components

Liebherr offer a full range of power options to suit different operational models. Whether it is diesel, electric or a
combination of both, the Liebherr RTG will deliver power when it is needed to ensure higher productivity.

Power Options

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.

Signicant savings on fuel bills are achievable when

compared with traditional RTG power options.

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.

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.

Full Electric

A full electric RTG from Liebherr delivers many
benets. 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 tted for
electric operation or an E-RTG solution can be retro
tted. 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 tted with an auxiliary generator

or connection for a portable generator to allow
movement between the stacks.
