Flat Crane Cable – Flexible NBR Festoon Cable for Hoist and Crane Systems

Product Overview

Our flat crane cable is engineered for demanding power transmission and control applications on moving equipment. It features a robust design that is waterproof, oil-resistant, cold-resistant, UV-resistant, abrasion-resistant, and flame-retardant. With a bending life exceeding 5 million flex cycles, it delivers outstanding durability in dynamic installations.

Compared to conventional round cables, the flat profile offers a significantly smaller bending radius, saving valuable installation space. Multiple cables can be stacked and bundled neatly together, simplifying cable management on cranes, hoists, and trolley systems.

Installation Note: To ensure optimal performance in long-travel or high-speed applications, a supporting strength member is recommended.

• Cores laid flat in a single row: For suspension lengths > 40 m and travel speeds > 2 m/s, we recommend integrating a steel wire or aramid yarn support.

• Cores arranged in a helical bundle: For suspension lengths > 80 m and travel speeds between 4–10 m/s, a steel wire strength member is recommended.

Key Features & Benefits

• Superior Flexibility & Long Service Life: Endures over 5 million bending cycles, reducing downtime and replacement costs.

• Compact, Space-Saving Design: Flat profile allows for a tighter bending radius than round cables and enables stacked installation.

• All-Weather & Harsh Environment Resistance: Excellent resistance to oil, water, UV radiation, cold, and abrasion.

• Enhanced Safety: Flame-retardant properties help prevent fire propagation.

• Versatile Core Configuration: Available with cores in a single-row flat layout for standard applications, or a helically stranded bundle for high-speed, long-distance travel.

4. FAQ

Q1: What is the main difference between a flat crane cable and a round crane cable?
A flat crane cable offers a much smaller bending radius than a comparable round cable, which saves installation space and reduces the mechanical stress on the conductors. Its shape also allows multiple cables to be stacked perfectly, providing a more organized and compact solution for festoon and reeling systems.

Q2: For what travel lengths and speeds can I use this flat cable without an integrated strength member?
For standard applications, the cable operates reliably without additional support. However, as a rule of thumb, if your suspension length exceeds 40 meters and travel speed is above 2 m/s, we strongly recommend integrating a steel wire or aramid yarn strength member. For helically stranded designs used at speeds of 4–10 m/s and lengths over 80 meters, a steel support is essential to bear the tensile load.

Q3: What materials are used for the jacket, and are they suitable for my environment?
Both the core insulation and outer sheath are manufactured from a high-quality, oil-resistant, and flame-retardant NBR compound. This makes the cable ideal for harsh industrial settings with exposure to lubricants, cutting fluids, UV radiation, and low temperatures down to -15°C during flexing.

Q4: Can you supply this cable with a specific core color code and a ground wire?
Yes. Our standard configuration includes color-coded or numbered cores with an integral yellow/green ground conductor. We can also produce custom color coding and core identification to match your specifications.

Q5: What standards does your flat crane cable comply with?
The conductor conforms to DIN VDE 0295 Class 5 and IEC 60228 Class 5 for superior flexibility. Our cables can also be supplied with RoHS and CE compliance documentation upon request to support your regional certification needs.
