Advantages of RMG for Yard Stack-

- Suitable for both Port and Rail Terminals

- Suitable for Various Yard Space Conditions

- Increased Yard Capacity with Wider and Higher Stack Possibilities

- Reduction in Emissions and Noise

- Minimal Maintenance

- Electric Supply - More Energy Efficient (Lower Running Costs)

Liebherr Anti - Sway System

Eight Rope Reeving

Advantages by Design

Minimal Spreader Positioning Times
NO - Sway: Hoist, Trolley & Travel Directions
Anti - Skew
No Additional Ropes or Devices Necessary
No HeadBlock - Reduced Rope Load
Lower Energy Consumption
All Electric Spreader - Less Maintenance

Increased Productivity of between 30 - 40% when compared to alternative designs.

Motors & Speed Control System

Motors / Suppliers

All Drives are Sized for Maximum Torque and Power
Requirements Guaranteeing Extended Lifetime.

All Major Components Sourced From Reputable European
Manufacturers

Speed Control System

The Control System used has been specifically developed
for container cranes by Liebherr, which has resulted in a
flexible, robust construction with exceptional reliability.

equipment is designed to maximise crane availability and
to minimise the necessity for highly skilled electronic
personnel.

-

Simultaneous operation of all main motors is possible. This means that the crane driver can Hoist, Trolley
and Crane Travel at the same time.
