Application fit

Is 3GRDGÖU right for your machine?

Specify 3GRDGÖU for STS and RMG/RTG container crane headblock-to-spreader gravity collector baskets where the cable must coil under its own weight without corkscrewing.

Spreader gravity collector basket

Suitable

Supple 3G silicone cores let the cable drop and coil smoothly by gravity into conical spreader baskets up to 160 m/min.

Free-hanging vertical run

Suitable

Central synthetic load-bearing core and double-sheath anti-torsion braid (RD) support vertical free-hanging loops up to 50–80 m.

Offshore platform & shipboard deck trays

Suitable

Heavy-duty 5GM3 polychloroprene outer sheath (GÖU) resists marine salt spray, hydraulic spreader oil, and UV sunlight.

Motorised monospiral reel

Not suitable

Optimised for gravity-fed collector baskets rather than high-tension horizontal travelling monospiral reels.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why does 3GRDGÖU use 3G silicone rubber core insulation inside a polychloroprene outer sheath?
In a gravity-fed spreader collector basket, the cable is not pulled into the basket by a motor — it must coil smoothly under its own weight as the crane trolley lowers. Silicone rubber ('3G') core insulation has ultra-low flexural modulus from -40 °C to +90 °C, preventing the cable from stiffening in winter while the tough 5GM3 polychloroprene outer jacket ('GÖU') protects against oil and impact.
What does every code letter in 3GRDGÖU stand for?
'3G' = silicone rubber core insulation, 'RD' = round cable with anti-torsion textile braid reinforcement over an inner sheath, 'G' = elastomeric rubber sheath, 'Ö' = oil-resistant outer jacket, and 'U' = flame-retardant (self-extinguishing) compound.
How is 3GRDGÖU suspended at the crane headblock and spreader basket?
Use a long-mesh stainless-steel Kellems/stocking cable grip combined with a strain-relief bell mouth (bend limiter) and swivel/fixed anchor shackles so tensile load transfers smoothly to the double sheath and central strain core.
How many cores are typically specified for container crane spreaders?
Standard twin-lift and telescopic STS spreaders typically use 30G1.5, 36G1.5, 42G1.5, or 36G2.5 (or hybrid power + optical/bus versions) to carry twistlock solenoids, landing-pin proximity sensors, and flipper motor controls.
