SPREADERFLEX — Complete Basket, Vertical Reeling and Mobile Harbour Crane Series

A comprehensive English engineering guide covering gravity-fed basket cables, dedicated fibre-optic basket designs, the vertical-reeling family now mapped to SPREADERFLEX REEL XPRT, the −50°C branch and the public SPREADERFLEX XTRM configuration.

1. Source hierarchy and counting rule

2019 3GSLTOE matrix
50 metric, AWG, bus and integrated-FO basket records.
2021 SYSLTOE matrix
31 dedicated LWL basket records with published tensile-force values.
2019 vertical matrix
28 CORDAFLEX(SMK)-V records, retained as the legacy matrix behind the new REEL XPRT mapping.
XTRM public flyer
One fully quantified representative mobile-harbour-crane configuration.
Counting rule: 110 published records are included. Arctic and new-brand mapping documents define product branches but do not publish additional complete matrices.

3. Basket-operation construction

SPREADERFLEX BSKT XPRT / 3GSLTOE-SYSLTOE basket-cable anatomy Representative bundled construction with central aramid/lead-ball support, screened pairs and an optional optical unit. 1. Black special PUR outer sheath 2. Control-core bundlesBundles are laid around the central support element. 3. EPR or special thermoplastic insulation3GSLTOE uses cold-rated EPR;SYSLTOE uses thermoplastic insulation. 4. Bare class-FS copper 5. Aramid around lead-ball cordsSized for a factor of safety of five at 50 m vertical suspension. 6. Optional optical element 7. Optional screened pairTinned Cu braid: ≥60% core screen, ≥80% twisted-pair screen.
The central support uses aramid threads woven around lead-ball cords. Its breaking load is designed for a safety factor of five when the cable is vertically suspended for 50 m. Larger constructions may use a round rubber filler with aramid threads.

4. Vertical-reeling construction

SPREADERFLEX REEL XPRT — legacy CORDAFLEX(SMK)-V vertical-reeling anatomy Representative control-plus-fibre design from the mapped 2019 matrix; exact current XPRT construction requires confirmation. 1. Yellow PCP outer sheathPROTOFIRM Special, abrasion and tear resistant. 2. Reinforced polyester braid 3. Yellow PCP inner sheath 4. Numbered control coresBare class-FS copper with high-stabilitythermoplastic insulation. 5. Central aramid support elementPublished Fmax includes the additional support capacity. 6. Optional fibre-optic group
The table is an official 2019 legacy matrix. The 2025 brand map renames the old CORDAFLEX(SMK)-V/-V-S family as SPREADERFLEX REEL XPRT, but does not state that every old Part number remains commercially current.

5. SPREADERFLEX XTRM public construction

SPREADERFLEX XTRM — published 37×2.5 + CAN BUS representative configuration Engineering interpretation of the public flyer image and stated features; exact production drawing and compounds are not published. 1. Black high-duty sheath systemExact compound is not stated in the public flyer. 2. Visible reinforcement braid 3. Thirty-seven 2.5 mm² cores 4. High-strength central supportShown as an engineering interpretation; exact construction is order-specific. 5. CAN BUS pair, 2×0.24 mm² Published performance points Tensile strength >4.5 kN · breaking strength >20 kN · 160 m/min · 90 m lift with 130 m total cable · 1.5 kg/m · 28.7 ±1.0 mm.

8. Complete 3GSLTOE basket matrix — 50 rows

The source table does not publish a row-by-row tensile-force column. F15 and the minimum 50 m support-breaking requirement are therefore shown only as derived engineering references.

14. Installation and acceptance checklist

  • Confirm BSKT XPRT, REEL XPRT, Arctic or XTRM before selecting dimensions.
  • For basket operation, follow the specified counter-clockwise lay direction and verify 30D/45D basket geometry against lift, speed and wind load.
  • Define the support-element termination; do not transfer suspended load through electrical conductors alone.
  • Confirm fibre type/count, optical budget, breakout length, splice/connector architecture and OTDR baseline.
  • For screened pairs, verify protocol impedance, attenuation and bonding.
  • For REEL XPRT, obtain a current datasheet rather than ordering from a legacy Part number alone.
  • For XTRM, obtain the exact construction drawing and confirm total cable length, lift height and support termination.

15. Failure mode and effects analysis

Wrong basket direction: reverse coiling introduces twist and unstable basket payout.
Undersized basket: diameter below 30D increases compression and loop damage.
Support bypass: electrical cores carry suspended mass instead of the aramid system.
FO microbending: basket pressure or guide geometry increases attenuation.
Legacy mapping error: an old CORDAFLEX-V Part number is treated as a confirmed current REEL XPRT code.
XTRM assumption: unpublished compounds or layer dimensions are inferred from a marketing image.
