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.
