Port Crane Cable

TEBAOFLEX port crane cables are built to move with the crane: round NSHTOU-J and PNCT cables for motorised or spring reels and spreader baskets, flat NGFLGÖU-J and screened NGFLCGÖU-J festoon cables, and round PUR-C-HF-J and CUR-2PNCT/3PNCT festoon alternatives. Ratings are 300/500 V, 600 V and 0.6/1 kV, with Class 5 or Class 6 copper, EPR insulation and chloroprene or halogen-free PUR sheaths for ship-to-shore, RTG and RMG cranes. YY, LiYY, YSLYSY and PUR-JZ control cables cover circuits that do not travel.

Selection Guide

Port Crane Cable Selection Guide

Model comparison, operating conditions and RFQ checklist.

A port crane cable is a flexible power, control or data cable built to move with the crane. It is wound on a motorised or spring-driven reel, carried in loops on a festoon trolley track, dropped into a spreader basket, or laid as fixed control wiring. Compared with installation cable it uses finely stranded conductors and rubber or polyurethane sheaths, and it serves ship-to-shore, RTG and RMG cranes, stacker-reclaimers and hoists.

Reeling cable or festoon cable: which does your crane need?

The cable-handling system sets the mechanical stress, so choose by system first.

  • Motorised or spring reel: a reeling cable is wound and unwound under tension and sees tensile load, torsion and layer pressure together. Choose a round cable with an anti-torsion braid between the sheaths, such as the NSHTOU-J type, or a PNCT reeling variant.
  • Festoon trolley: a festoon cable hangs in loops and bends repeatedly with little tension. Flat NGFLGÖU-J and screened NGFLCGÖU-J cables stack on trolley saddles and bend in one plane; PUR-C-HF-J and CUR-2PNCT/3PNCT are the round alternatives.
  • Basket or spreader: the cable drops vertically and must coil without kinking. The PNCT page covers basket operation; state drop height and basket diameter in the enquiry.
  • Fixed and control wiring: circuits that do not travel can use the auxiliary control cables listed below.

Which operating conditions decide the choice?

  • Bending radius: compare drum, sheave, roller and saddle diameters with the minimum bending radius for moving use, not the fixed-installation figure.
  • Speed and acceleration: these set the dynamic tensile load. Check the product-page limit for reeling, festoon or chain use.
  • Tensile load: compare the load from suspended length and cable weight with the permitted conductor tensile stress.
  • Water, oil and weather: quayside cables meet rain, salt spray, UV and lubricants. Confirm sheath resistance and immersion suitability.
  • Temperature: use the limit for a cable in motion, which is narrower than for fixed laying.
  • Flame and halogen-free: specify halogen-free only where the product page states it, and name the flame test required.
  • EMC: use screened constructions on converter-fed drives.

For a replacement-planning example, see the Hai Phong 6.6 kV 3PNCT replacement review, including the reel geometry, drawing and inspection information to confirm before production approval.

Frequently Asked Questions

Quick answers about Port Crane Cable from our engineers.

01Does my crane need a reeling cable or a festoon cable?

Choose by the cable-handling system. A reeling cable is wound and unwound on a motorised or spring reel and takes tensile load, torsion and layer pressure together, so use round NSHTOU-J with an anti-torsion braid or a PNCT reeling variant. A festoon cable hangs in loops on a trolley and bends repeatedly with little tension: flat NGFLGÖU-J or NGFLCGÖU-J, or round PUR-C-HF-J or CUR-2PNCT/3PNCT.

02When is a screened festoon cable needed?

Use a screened construction on converter-fed drives. NGFLCGÖU-J adds a tinned copper wire braid to the flat NGFLGÖU-J design for frequency-conversion drives, servo systems and combined power and signal circuits, and the braid must be grounded. PUR-C-HF-J is a round 0.6/1 kV alternative with a tinned copper braid of at least 80 % coverage under a halogen-free, flame-retardant PUR sheath.

03Which travel speeds and tensile loads are stated for reeling and festoon use?

NSHTOU-J is listed for horizontal reeling at up to 120 m/min with a maximum acceleration of 0.4 m/s², and the tensile stress on the conductors may not exceed 15 N/mm². PUR-C-HF-J lists up to 200 m/min on festoon systems, 60 m/min horizontal and 200 m/min vertical reeling, a 15 N/mm² maximum tensile load and ±25°/m torsion. Compare these limits with the crane's speed and acceleration.

04What is the difference between CUR-2PNCT and CUR-3PNCT?

Both are 600 V AC festoon cables to JIS C 3327 with Class 5 tinned copper, EPR insulation and a chloroprene sheath in 2 to 24 cores. CUR-2PNCT is the standard grade for light and medium-duty festoon up to 60 m travel, such as workshop hoists and light gantry cranes. CUR-3PNCT adds a canvas reinforcement layer under the sheath for heavy-duty, long-travel festoon on RTG and RMG cranes and stacker-reclaimers.

05Can the YY, LiYY, YSLYSY or PUR-JZ cables be used on reels or festoons?

Their product pages give no reeling or festoon rating. They are general-purpose low-voltage types for fixed or occasionally moved wiring: YY and LiYY are unscreened PVC cables, YSLYSY has an overall copper braid or foil/braid screen, and PUR-JZ has a PUR sheath with numbered cores and a green-yellow earth for handling equipment. Confirm voltage, temperature and motion duty for the exact variant.

06What should I send with a port crane cable RFQ?

The crane type and handling system (reel, festoon, basket or chain); rated voltage, cores, cross-sections, screening and any data or fibre elements; travel length or lift height, speed and acceleration; drum core, sheave and roller diameters and trolley spacing; ambient temperature and exposure to water, oil, UV or salt; the required standard, flame or halogen-free requirement and documents; and the length per drum, with the existing cable marking for replacements.
