Gantry Crane Reel Cable (Drum Cable)
Product Overview
Engineered for the most demanding continuous flexing and reeling systems, our gantry crane reel cable delivers outstanding mechanical durability and a dramatically extended service life. It combines high abrasion resistance, UV stability, tensile strength, and superior flexibility to prevent the common failure modes found in heavy industrial environments — such as tangling, twisting, abrasion, deformation, and snagging. Compared to standard rubber flat cables, this reeling cable provides at least 3 to 5 times longer service life.
Whether installed in dry or damp indoor settings, or in free-hanging reeling systems without forced guidance, the cable performs reliably in port cranes, large stockyards, mining operations, and heavy-duty loading/unloading terminals. It is purpose-built to protect against cable damage while ensuring smooth, uninterrupted coiling and uncoiling.

Frequently Asked Questions
What outer jacket material is used in this reel cable?
The outer jacket is made of premium imported polyurethane (PUR) sourced from the US. PUR delivers exceptional abrasion resistance, oil resistance, UV stability, and flexibility — making it the material of choice for demanding reeling applications.
What is the minimum bending radius for moving applications?
For flexing installations, the minimum bending radius is 7.5 times the cable outer diameter. For fixed installations, it can be as tight as 5 times the outer diameter.
Can this cable operate in extremely cold environments?
Yes. The cable is specifically rated for continuous operation from -40°C to +105°C in both fixed and high-flex moving conditions, making it suitable for freezer terminals, cold climate ports, and high-temperature process areas.
Is a flame-retardant version available?
Absolutely. Flame-retardant properties can be added as an option. Please specify your requirements when you inquire, and we will engineer the cable to meet the relevant IEC or local standards.
How does the service life compare to ordinary rubber flat cables?
Our PUR-jacketed reel cable typically lasts 3 to 5 times longer than conventional rubber flat cables due to the superior mechanical properties of the polyurethane jacket and the high-flex conductor construction.
Can I order custom core configurations and jacket colors?
Yes. Cores can be identified by numbers or colors, and the outer jacket is available in grey, black, orange, or any custom color to match your installation or safety marking requirements.
