Drum & Reeling Cable | Flexible Round Trailing Cables for Cranes

Industrial drum and reeling cables for cranes, gantries and port equipment. LV 0.6/1 kV rubber and PUR designs, tensile up to 30 N/mm², travel speed to 240 m/min. OEM available.

Drum & Reeling Cables for Industrial Cranes and Port Equipment

Drum and reeling cables are purpose-engineered for cylindrical reel and mono-spiral drum applications where the cable is continuously wound and unwound during crane or hoist operation. Unlike standard flexible cables, reeling cables must simultaneously resist torsion, tensile pull, abrasion, and repeated bending — often at high speed in harsh outdoor environments.

Our range covers standard-duty rubber-sheathed designs through to high-performance PUR halogen-free cables for demanding container terminal and offshore crane operations.


Key Design Features

  • Very finely stranded copper conductors (class FS / class 5) for maximum flex life
  • Anti-torsion polyester braid vulcanized between inner and outer sheaths
  • EPR insulation (PROTOLON compound) — superior flexibility in cold environments
  • Rubber (PCP) or PUR outer sheath options — oil, ozone, and UV resistant
  • Central aramid support element available for vertical/spreader reeling
  • Torsional endurance: ±50°/m sustained
  • Minimum S-type direction change distance: 20×D
  • Optional integrated bus cables: ASI, Profibus, CAN-Bus, Profinet, Industrial Ethernet
