Vertical / spreader reel
Primary duty: vertical motorized spreader reels up to 240 m/min (RXX) or 300 m/min (RXX-D) with central strain relief.
Product
Extra-heavy-duty (N)SHTOEU-J vertical spreader reeling cable with central strain relief, short-lay cores and bonded yellow dual-PCP sheath with anti-torsion braid for container cranes and grab dredgers.
Typical values for this cable type, based on DIN VDE 0250-814 — confirmed in the datasheet and quotation for your order.
Application fit
RXX and RXX-D are built for vertical motorized spreader reels and grab-dredger hoists combining high suspended tensile loads (3,200–6,000 N), rapid vertical acceleration (up to 240 m/min on RXX and 300 m/min on RXX-D), ±50 °/m twist and wet outdoor or submerged operation.
Primary duty: vertical motorized spreader reels up to 240 m/min (RXX) or 300 m/min (RXX-D) with central strain relief.
Rated for temporary water submersion down to 50 m depth on grab dredgers and floating dredgers.
Suitable for high-speed horizontal and diversion-roller reeling with ±50 °/m twist tolerance.
Engineered for tensioned motorized drum winding; use 3GSLTOE or BSKT XPRT SYSLTOE FO for gravity collector baskets.
