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

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.
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.
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.
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.
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.
