RONDOFLEX & PLANOFLEX Crane Festoon & Travelling Cable Series (0.6/1 kV)

High-speed container crane boom festoons, steelworks ladle crane trolleys and automated bulk-handling gantries use two complementary 0.6/1 kV festoon geometries: round cables (RONDOFLEX series) for heavy single- and multi-core loops that must resist wind-induced lateral sway, and flat cables (PLANOFLEX series) for compact multi-tier stacking where trolley parking length and saddle bend radius are constrained.

The round RONDOFLEX series (aligned with DIN VDE 0250-814 / (N)GRDGÖU-J/O) combines Class 5/6 flexible copper conductors and +90 °C 3GI3 EPR core insulation with a pressure-extruded inner elastomer bedding and a heavy-duty black 5GM3/5GM5 polychloroprene outer sheath. Because the inner bedding locks the short-pitch core assembly without stiff metallic armour, RONDOFLEX hangs smoothly in deep catenary loops on motorized festoon carriages running at travel speeds up to 240 m/min.

The flat PLANOFLEX series (aligned with DIN VDE 0250-809 / NGFLGÖU-J/O) aligns 4 to 42 insulated cores in one or two parallel horizontal rows inside a flexible 5GM3 polychloroprene flat web jacket, enabling minimum dynamic bending radii down to 8 × to 10 × cable thickness. Jiangsu Tebaoflex Special Cable Co., Ltd. holds third-party verification of conformity (ICR, cert. ICR/VC/HTT260331) against the DIN VDE 0250 series based on test reports XMT0202600330W/EMC and /LVD (2025-03-30).

Indicate whether your festoon system uses round RONDOFLEX or flat PLANOFLEX saddles, along with core count, cross-section, loop depth and trolley travel speed. TEBAOFLEX manufactures custom festoon lengths from a 50 m minimum order quantity with a standard lead time of 7–45 working days.

For related round and flat VDE rubber crane festoon cables, compare these specifications: (N)GRDGOEU-J/-O 0.6/1 kV Round Festoon Cable (for VDE-designated extra-flexible rubber round festoon loops at 0.6/1 kV); (N)GFLCGÖU-J/O 0.6/1 kV Screened Rubber Flat Festoon & Reeling Cable (for EMC-screened flat rubber festoon and VFD crane drive circuits at 0.6/1 kV). Verify round versus flat trolley saddle geometry, core count, and bend radius before ordering.

Construction

The representative construction illustrates RONDOFLEX (N)GRDGÖU-J 0.6/1 kV 12G2.5 mm² Round Crane Festoon Cable (alongside PLANOFLEX flat geometry): 12 Class 5/6 extra-flexible copper cores insulated with +90 °C 3GI3 EPR cabled in a short pitch around a central elastomeric filler, locked in a vulcanized light-grey 5GM3 inner sheath and protected by a supple, flame- and oil-resistant black 5GM3/5GM5 polychloroprene rubber outer sheath.

Applications

Select round RONDOFLEX for high-wind outdoor port crane boom festoons (where round profiles minimize aerodynamic drag and twist) and flat PLANOFLEX for indoor/outdoor C-rail and I-beam trolleys requiring tight saddle radii.

• Ship-to-shore (STS) container crane boom catenary festoon systems operating at trolley speeds up to 240 m/min.
• Overhead bridge cranes, steelmill charging cranes, foundry hoists and bulk grab cranes with I-beam or box-beam festoon carriages.
• Automated high-bay warehouse stacker cranes, shipboard gantry cranes and electroplating/galvanizing hoist lines.
• Flexible single-core (1×50 to 1×240 mm²), multi-core power (4G2.5 to 4G120 mm²) and multi-core control (7G1.5 to 42G2.5 mm²) festoon loops.

For container crane boom festoons, steel-mill overhead cranes, and high-speed trolley tracks, review these references: Festoon System: Components, Track Types, and Industrial Cable Selection (for trolley spacing, loop depth, and cable pack stacking engineering); (N)GRDGCGOEU-J 0.6/1 kV Screened Festoon Cable (for round copper-screened rubber festoon cables on inverter-driven cranes at 0.6/1 kV). Confirm trolley travel speed, loop sag, and outdoor weather resistance before installation.

Specifications

These are the standards this construction is designed and manufactured to (DIN VDE 0250-809 for PLANOFLEX flat cables and DIN VDE 0250-814 / (N)GRDGÖU for RONDOFLEX round cables).

On round festoon systems, clamp each cable in contoured rubber saddle blocks with a saddle arc radius of at least 6 × to 7.5 × cable outside diameter.

Continuous current ratings are stated at +30 °C ambient air per DIN VDE 0298-4.
