Products Description
Gantry crane cables are heavy-duty flexible cables used for port gantry cranes, container RMG cranes and site lifting equipment.
These cables undergo constant winding-unwinding, pulling and bending as cranes move back and forth. Fine-stranded tinned copper conductors stand up to repeated dynamic flexing to avoid wire breakage. Heavy-duty rubber or PUR outer sheath offers good resistance against abrasion, oil and outdoor UV exposure. Commonly deployed in container terminals, yards and heavy-lift working sites.

FAQs
Q1: What makes gantry crane cable different from normal flexible cables?
A: It is engineered for ≥5 million winding-unwinding cycles. Reinforced sheath provides superior abrasion and oil resistance for continuous port-yard operation.
Q2: What is the cable shielding performance?
A: 65 dB+ shielding effectiveness, effectively suppresses EMI interference from crane motors and power units to keep signal stable.
Q3: What kinds of sites suit this cable?
A: Mainly for port gantry cranes, RMG container cranes and heavy-duty lifting yards working under-20℃~+80℃.
