YSLTOE-J Cable for Gravity-Feed Collector Baskets
YSLTOE-J 300/500V cable is designed for gravity-feed collector baskets on high-speed container cranes. Unlike a general control cable, this cable must move repeatedly into and out of a basket while keeping the core bundles stable and free from torsion. The construction uses six core bundles laid around a central lead ball rope and support element, helping the cable settle correctly in the basket during fast crane operation.
Key Engineering Features
- Basket-specific construction: The cable is built for gravity-feed collector baskets, where cable weight, lay direction and basket diameter directly affect service life.
- Central lead ball rope: The support element helps the cable fall and stack in a controlled way, reducing the risk of disorderly looping inside the basket.
- Kevlar support: Kevlar reinforcement supports tensile loading during repeated crane movement without relying only on copper conductors.
- Anti-torsion lay-up: Six core bundles are stranded around the central support to reduce torsional stress during collection and payout.
- Halogen-free PUR sheath: The PUR sheath provides abrasion resistance for crane environments while supporting halogen-free material requirements.
- High-speed operation: Rated for working speeds up to 160m/min when correctly installed in a suitable basket system.

Selection Notes for Buyers
For YSLTOE-J cable selection, confirm the number of cores, conductor cross section, basket diameter, travel speed, working temperature and cable routing direction. To avoid cable damage, the cable should be installed counter-clockwise in the basket and the basket diameter should be greater than 30 times the cable overall diameter. For multi-layer collection, current capacity should be checked against the number of reeled layers and corrected with the ambient temperature de-rating factor.
