TEBAOFLEX YSLTOE-J (YSLTÖ-J) is a compact, torsion-balanced 300/500 V halogen-free PUR spreader basket control cable designed for gravity-fed collector baskets on high-speed STS (ship-to-shore), RMG, ASC, and RTG container cranes. Unlike concentric-lay control cables that twist and birdcage during rapid hoist deceleration, YSLTOE-J arranges 24 to 60 flexible copper control cores into reverse-twist multi-core sub-bundles around a high-modulus synthetic aramid and optional weighted ballast center so loops drop cleanly at speeds up to 160-240 m/min.
1. Application Scope & Spreader Basket Family Comparison
YSLTOE-J is purpose-built for container spreaders where 24 V DC, 110 V AC, or 230 V AC control, twistlock proximity sensors, telescopic beam limit switches, corner flipper valves, and twin-lift I/O signals are consolidated into a single slim vertical basket cable:
- Ship-to-Shore (STS) Quay Cranes: High-lift vertical loops (
50-85 mfree suspension from trolley/headblock to vessel cell guides) requiring high tensile safety margin and wind-stable gravity coiling. - Intermodal RMG & Automated Stacking Cranes (ASC): Continuous 24/7 yard stacking cycles where compact
300/500 Vcable diameter maximizes coil capacity inside narrow spreader collector baskets. - RTG Cranes & Straddle Carriers: Outdoor marine terminals exposed to hydraulic oil mist, salt spray, tropical UV radiation, and sub-zero winter operation down to
-40°C.

2. Cable Construction (Verified Against 42G Factory Cross-Section)
As shown in our factory macro cross-section photograph, YSLTOE-J eliminates internal stranding torque by grouping individual control conductors into symmetrical sub-bundles around a dedicated load-bearing and ballast core:
3,000 N to 12,000 N), available with an encapsulated lead-bead / weighted elastomer ballast core so lightweight control cables drop rapidly into the collector cone in high winds.-40°C.YSLTOE-O without PE available).5-core or 6-core sub-bundles around soft textile fillers, then cabled in a counter-balanced short lay around the central support core with non-woven gliding tape.3.

Pre-Tension Relaxation & Basket Laying Rule: Never pull YSLTOE-J off the side flange of a flat-lying reel, as each coil injects 360° of permanent twist. Always pay off tangentially from a rotating drum stand, suspend the cable freely from the headblock for 12-24 hours before locking the lower basket stocking grip, and verify the collector basket rim diameter exceeds 25-30 × OD.

5. Frequently Asked Questions (YSLTOE-J Selection & Basket Commissioning)
When should crane engineers specify 300/500 V YSLTOE-J instead of 0.6/1 kV 3GSLTOE spreader cable?
Specify 300/500 V YSLTOE-J when the telescopic spreader operates on hydraulic power packs located on the headblock or uses low-voltage 24 V / 110 V / 230 V control, twistlock proximity sensors, flipper solenoids, and twin-lift I/O (24 to 60 cores). Its thin-wall thermoplastic core insulation reduces overall cable diameter and basket fill volume by 18-25% compared with 0.6/1 kV EPR-insulated 3GSLTOE Spreader Cable.
What is the purpose of the central weighted ballast core visible inside the YSLTOE-J cross-section?
High-core-count 300/500 V PUR control cables are lighter per meter than thick rubber power cables. Integrating a central high-modulus aramid tensile core with an optional encapsulated lead-bead ballast increases linear mass-to-diameter ratio so the cable drops cleanly into the conical collector basket against 20-25 m/s coastal crosswinds without loop blow-out during 160-240 m/min empty-spreader hoists.
How should YSLTOE-J be coiled into the spreader collector basket during commissioning?
Unreel YSLTOE-J axially from a rotating cable drum without pulling loops over a stationary flange. Hang the cable over the full crane hoist height for 12-24 hours to relax handling stress before clamping the bottom basket grip, then feed coils into the collector basket in the natural lay direction (typically counter-clockwise, matching sheath lay arrows). Recommended collector basket outer diameter is 25 to 30 times cable OD.
What does the -J suffix mean in YSLTOE-J (câble YSLTOE-J)?
In DIN VDE control cable nomenclature, -J indicates that one conductor in the outer bundle is a continuous green/yellow protective earth (PE) core, while all remaining control cores are black with white sequential numbers. YSLTOE-O (without green/yellow core) is also available upon request.
Configure YSLTOE-J for Your STS, RMG or RTG Spreader Basket
Share your core count (30G2.5, 36G2.5, 42G2.5, 48G2.5, or custom), vertical drop height, hoist speed, collector basket inner/outer cone diameters, and weighted vs. standard aramid center preference.
