PANZERFLEX-L & PANZERFLEX-VS Heavy-Duty Port Reeling & Vertical Spreader Cable (0.6/1 kV)

Port container terminals and bulk cargo quays rely on two distinct 0.6/1 kV reeling duties: horizontal or monospiral gantry travel reels (PANZERFLEX-L series) and vertical hoist-synchronized spreader reels (PANZERFLEX-VS series). TEBAOFLEX manufactures both constructions in accordance with DIN VDE 0250-814 to withstand continuous salt-laden coastal humidity, high acceleration and millions of reverse bending cycles.

PANZERFLEX-L is engineered for horizontal gantry, trolley and boom-hoist reels (from 4G2.5 mm² up to 3×240 + 3G50 mm² and 7G–42G control configurations) operating at travel speeds up to 160–240 m/min. Fine-stranded Class 5 tinned copper conductors and +90 °C 3GI3 EPR insulation are cabled in a short lay pitch, locked inside a pressure-extruded 5GM3 inner sheath, reinforced with an open-weave aramid anti-torsion braid and protected by a black 5GM5 chloroprene rubber outer sheath.

PANZERFLEX-VS is purpose-built for vertical spreader reels on STS, RMG and RTG cranes (typically 19G2.5 to 48G2.5 mm², or hybrid power + control + bus/fibre-optic layouts), where the cable hangs vertically from the trolley boom down to the container headblock under high wind loads and twistlock shock impacts. A reinforced central aramid load-bearing core and double-counter-helical anti-torsion braid support vertical free-suspension heights up to 60 m and dynamic tensile loads up to 30 N/mm².

State whether your application requires PANZERFLEX-L (horizontal drum) or PANZERFLEX-VS (vertical spreader reel), along with the core configuration, travel speed and drum diameter. TEBAOFLEX supplies custom lengths from a 50 m minimum order quantity with a standard lead time of 7–45 working days.

For related vertical container spreader cables and polyurethane spreader feeders, compare these specifications: RXX / TRA-RF Spreader Vertical Reeling Cable 0.6/1 kV (for vertical spreader drum reeling and torsion-stabilized hoist drops at 0.6/1 kV); XTRM (N)SHT11Y Crane Spreader PUR Cable 0.6/1 kV (for polyurethane-sheathed container spreader reeling and basket duty at 0.6/1 kV). Verify horizontal drum reeling versus vertical gravity-fed spreader duty before ordering.

Construction

The representative construction illustrates PANZERFLEX-VS 0.6/1 kV 36G2.5 mm² Vertical Spreader Reeling Cable: 36 Class 5/6 extra-flexible tinned-copper control cores insulated with high-modulus +90 °C EPR (numbered black cores plus green/yellow earth core) cabled in concentric reverse-lay layers around a heavy central aramid tension rope, enclosed in a light-grey vulcanized 5GM3 inner sheath, a bidirectional aramid anti-torsion braid and a black tear- and oil-resistant 5GM5 polychloroprene outer sheath.

Applications

Specify PANZERFLEX-L for horizontal gantry, portal and trolley motorized drums, or PANZERFLEX-VS for vertical spreader reels and gravity spreader baskets on container cranes.

• PANZERFLEX-VS: Vertical motorized spreader cable reels on ship-to-shore (STS) quay cranes, RMG/ASC stacking cranes, RTG yard cranes and mobile harbour cranes (MHC).
• PANZERFLEX-L: Main low-voltage gantry travel reels, boom-trolley reels and magnet/grab auxiliary reels on port cranes and bulk unloaders.
• Telescopic twin-lift container spreaders requiring 24G to 48G control cores or hybrid power (4G10/4G16) + control + optical fibre in a single vertical reeling cable.
• High-speed port reeling service up to 160–240 m/min and -35 °C to +80 °C coastal ambient temperatures.

For ship-to-shore spreader reels, RMG/RTG gantry drums, and telescopic spreader feed systems, consult these resources: Port & Container Crane Cable Solutions (for integrated STS, RTG, RMG, and container spreader cable engineering); PNCT Spreader Basket Cable — 2PNCT-T-U, SPD and SC Types (for Japanese-standard gravity-coil spreader basket service). Check hoisting speed, vertical suspension length, and anti-torsion braid tension before installation.

Specifications

These are the standards this construction is designed and manufactured to (DIN VDE 0250-814 and DIN VDE 0298-4).

For vertical spreader reels (PANZERFLEX-VS), always terminate the cable with a basket-weave strain-relief grip (Kellems-type sock) and anti-rotation swivel at the spreader headblock.

Third-party verification of conformity (ICR, cert. ICR/VC/HTT260331) against DIN VDE 0250-814 is based on test reports XMT0202600330W/EMC and /LVD (Shanghai Ximo Testing Technology, 2025-03-30).
