Liman

Motorized cable trolley for round cables with AC or DC technology. Depending on speed and load, it comes with a patented compact drive (Progr. 0380) or with a gear motor (Progr. 0385). The entire system consists of motorized cable trolleys, a frequency converter control for optimizing movement and cable trolleys from programs 0365 and 0375.

Main applications

• High-speed STS-container cranes of all Panamax classes
• Special overhead bridge cranes
• Scrap and ladle cranes in steel mills
• High-speed conveyor systems
• Transport systems

The requirements of today's systems, especially in container handling, often exceed the physical limitations of conventional systems when it comes to speed, acceleration and cable package weight. The application of motorized cable trolleys in combination with non-motorized cable trolleys allows for controlled acceleration and deceleration. This synchronization with the consumer makes it possible to increase the travel speeds of the entire system enormously. In addition, wear and maintenance work are reduced considerably, increasing the availability of the complete facility and minimizing the overall costs.

Special features of cables for Festoon Systems

• Low weight and small diameter due to a stranded layered conception. In the case of power cables, the earth conductor is split into three conductors.
• Resistant to alternating bending loads due to finely stranded conductors
• Sheathing compounds with very high resistance to outdoor atmospheric conditions
• Notch-resistant sheathing compounds with high resistance to tearing, highly resistant to stress caused by continuous bending at the bottom of the loop
• Robust outer sheath designed to absorb impact forces
• High axial rigidity and resilience due to pressure filled extrusion in interstices
• Highly resilient cables allow the smallest possible bending radius and therefore, short system lengths
