RTG Reeling Cable (Rubber Tyred Gantry Crane Reeling Drum Cable)
Product Overview
This heavy-duty reeling cable is purpose-engineered for rubber tyred gantry (RTG) cranes and similar equipment operating in demanding industrial environments. It combines extreme abrasion resistance, superior flexibility, high tensile strength, and exceptional tear resistance to withstand continuous reeling and unreeling cycles on cable drums. The specially compounded insulation and jacket materials also deliver reliable waterproof, oil-resistant, UV-resistant, and flame-retardant performance.
Compared with ordinary rubber flat cables, this reeling drum cable offers a service life at least three to five times longer, significantly reducing downtime and replacement costs. It is designed for dry or damp indoor locations and for unguided, freely reciprocating movements without forced guidance – especially in applications where frequent bending and coiling on large reels protect the cable against tangling, abrasion, snagging, and scatter.
Typical applications span container terminals, bulk stockyards, mining operations, large loading and unloading yards, and other harsh-duty sites where RTG cranes and reeling systems must perform reliably.

4. FAQ
Q: How does this RTG reeling cable achieve a longer service life?
A: The combination of super-fine VDE 0295 Class 6 copper conductors, a specially formulated PVC insulation, a high-strength inner sheath, and an imported polyurethane (PUR) outer jacket results in extreme flexibility, abrasion resistance and mechanical strength. Under comparable reeling conditions, these features extend the operational life to at least 3–5 times that of ordinary rubber flat cables.
Q: What is the temperature rating for continuous flexing applications?
A: The cable is rated for a continuous conductor operating temperature range from -40°C to +105°C in both fixed and moving installations, making it suitable for cold storage terminals and high-heat tropical port environments alike.
Q: Can the cable be customized for specific core counts, color coding or jacket color?
A: Yes. The core identification can be produced with numbering or color coding according to your project standards, and the outer PUR jacket can be supplied in grey, black, orange or other custom colors. Minimum order quantities may apply for unique color formulations.
Q: What is the minimum bending radius I should allow on the cable drum?
A: For fixed routing, allow a bend radius no smaller than 5 times the cable’s short diameter (flat cables) or outer diameter (round cables). For moving, flexing and reeling installations, the radius should be at least 7.5 times that dimension to ensure full mechanical and electrical life.
Q: What is the typical lead time for a custom-configured RTG reeling cable?
A: Lead times depend on the specific configuration, order volume and current production schedule. For a precise delivery estimate, please reach out to our sales team with your target specifications and quantity.
