Port & Terminal Crane Wire Rope
Port and terminal cranes, including RMG, RTG, and ship unloaders, run rope under continuous, high-cycle loading, which is why TJ Steel Rope offers the TG FLEX-7 construction specifically optimized for container-crane service. The standard catalog range for this segment also includes compacted 6xK and 8xK rope for higher breaking force at a given diameter. All constructions are tensile tested against their declared minimum breaking force before shipment. See Factory & Quality for the full testing process.
Selecting rope for port cranes
Built for round-the-clock cycles
Quay cranes, RMG and RTG yard cranes and ship unloaders run rope through millions of short, heavy cycles with constant multi-layer spooling. TG FLEX-7 is purpose-built for that duty, with compacted 6×K and 8×K rope where higher breaking force matters more than the last word in fatigue life.
