Application fit

Is CRANE FO 2×12/125 right for your machine?

CRANE FO 2×12/125 combines a thick 5GM5 thermosetting rubber outer jacket with a high-tenacity multifilament anti-torsion braid (1,500 N continuous / 2,000 N dynamic pull) to protect 24 optical fibers on motorized and spring-driven crane cable reels.

Motorised monospiral reel

Suitable

Primary duty: horizontal motor-driven and spring-driven crane, gantry and stacker-reclaimer reels up to 120 m/min.

Cylindrical / multi-layer drum

Suitable

Suitable for monospiral and cylindrical reeling drums with ≥ 250 mm minimum bend radius.

Spreader gravity collector basket

Not suitable

Built for tensioned motorised reels; for free-coiling gravity baskets use a dedicated basket cable.

FAQ

Questions engineers ask first

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

Why choose a 5GM5 rubber outer sheath instead of PUR for optical reeling?
On motorized and spring-driven cable reels, the thicker 14–16 mm 5GM5 thermosetting elastomer jacket provides superior radial crush cushioning on multi-layer drums, higher dynamic tensile capacity (2,000 N vs 1,500 N), and consistent grip on drive sheaves.
What minimum drum diameter is required for CRANE FO 2×12/125?
The minimum bending radius is 250 mm, corresponding to a minimum reel drum barrel or deflection sheave diameter of 500 mm.
How are the 24 fibers organized inside the cable?
They are housed in two colour-coded loose buffer tubes of 12 fibers each, with individual fibers colour-coded 1 to 12 according to ANSI/TIA/EIA-598-A.
Can CRANE FO 2×12/125 be used with multi-channel fiber-optic rotary joints?
Yes. The 2 × 12-fiber loose-tube construction is designed for termination inside reel slip-ring housings and multi-channel optical rotary joints on RMG, RTG and bulk-handling cranes.
