3GSLTOE Spreader Cable is a 0.6/1kV heavy-duty flexible cable for gravity-fed collector baskets and vertical hanging routes on container-crane spreaders. TEBAOFLEX supplies this model for projects that require stable power, control and optional data transmission while the cable repeatedly travels, bends and carries its own suspended load.
This is a project-configured cable: core count, cross-section, control circuits, screen arrangement, data elements, support construction and final test requirements are agreed from the crane duty cycle and installation geometry before manufacture.
Applications for 3GSLTOE Spreader Cable
- Container crane spreaders and load-lifting equipment
- Gravity-fed collector basket systems
- Vertical hanging and basket-coiling cable routes
- STS, RTG and RMG crane installations
- Outdoor port and terminal machinery with repeated dynamic movement

Reference construction
The following construction is based on the supplied reference parameters and is subject to TEBAOFLEX engineering confirmation for the final order:
- Conductor: extremely fine-stranded bare copper for flexible movement
- Core insulation: EPR-based compound with numbered light-colour core identification; protective earth green/yellow where required
- Screen options: tinned-copper braid for screened cores or twisted pairs when specified
- Core arrangement: cores laid into bundles around a central support element
- Support option: aramid reinforcement selected for hanging length, cable mass and tensile requirement
- Outer sheath: black special PUR compound

Reference control-cable configurations
These examples help with preliminary layout planning. Outer diameter, bending radius, mass and current capacity change with the exact conductor count, cross-section, screen and data-element combination.
| Control configuration | Outer diameter range | Minimum free-moving bend radius | Approx. weight | Current capacity |
|---|---|---|---|---|
| 24 x 2.5 mm² | 29.1–32.1 mm | 161 mm | 1780 kg/km | 30 A |
| 36 x 2.5 mm² | 34.5–37.5 mm | 188 mm | 2780 kg/km | 30 A |
| 24 x 3.5 mm² | 32.0–35.0 mm | 175 mm | 2350 kg/km | 39 A |
| 42 x 3.5 mm² | 42.4–45.4 mm | 227 mm | 4510 kg/km | 39 A |
| 7 x 4 mm² | 18.1–20.1 mm | 101 mm | 670 kg/km | 41 A |
Integrated bus elements, screened pairs and fibre-optic units can be considered where the crane architecture requires combined power, control and data functions. Send the control-core schedule, communication protocol, hanging length and basket dimensions to TEBAOFLEX for a configuration review.
Installation and selection notes
For collector-basket systems, cable lay direction, basket diameter, basket height, hanging length and strain-relief location should be defined with the crane designer. As a reference, basket diameter can be planned at a minimum of 30 x cable diameter and basket height at approximately 45 x cable diameter; the final installation drawing takes precedence. This model is intended for vertical basket operation, not as a substitute for every reeling or festoon cable duty. For alternative motion systems, compare our 0.6/1kV rubber festoon cable and YSLTOE-J spreader basket cable.

Frequently asked questions
Can the 3GSLTOE Spreader Cable include data elements?
Yes. Screened bus elements or fibre-optic units can be evaluated as part of a project-specific composite construction. Specify the protocol and required element count for confirmation.
Is this a standard off-the-shelf cable?
No. This page presents a defined 0.6/1kV spreader-cable model with reference parameters. Final construction is confirmed for the crane, basket route and operating conditions.
Can it be used in cold outdoor port conditions?
The reference construction covers fixed and flexible temperature ranges, but compound selection and final suitability must be confirmed for the actual low-temperature requirement and duty cycle.
