Flat Cable for Crane

Description:

The flat cable for cranes is a specialized cable featuring a flat ribbon-like design, primarily used for power supply (such as festoon system) and signal control in mobile equipment such as overhead cranes and hoists.

Its key characteristics include:

  • High tensile strength

  • Excellent weather resistance

  • Small bending radius

  • Superior resistance to abrasion, oil, and corrosion

​

These attributes enable reliable performance in harsh environments ranging from -15°C to +80°C.

​

The cable structure consists of multi-stranded finely stranded oxygen-free bare copper conductors, insulated with a special elastomer compound or PVC material. Certain models may incorporate steel wire ropes on both sides of the cores to further enhance tensile strength.

​

It is widely used in metallurgy, electric power, port logistics, shipbuilding, and other industries involving mobile mechanical equipment.

Structural Features:

  • Conductor Design:
    Utilizes multi-stranded finely twisted oxygen-free bare copper wires to ensure excellent conductivity and flexibility.

  • Insulation Material:
    Constructed with a special blended elastomer or nitrile/PVC composite material, offering both oil resistance and superior aging resistance.

  • Reinforcement Components:
    Optional galvanized soft steel wire ropes or aramid yarns can be integrated as tensile reinforcement. Certain models support the integration of steel wire ropes on both sides of the core conductors for enhanced tensile strength.

Advantages: 

  1. Environmental Adaptability:
    Engineered for extreme conditions, the cable offers excellent resistance to cold (as low as -55°C), UV radiation, water, and flame—making it suitable for outdoor and harsh industrial environments.

  2. Mechanical Performance:
    With a bending radius as small as 7.5 times the cable thickness, the flat design conserves installation space and effectively prevents cable twisting or entanglement.

  3. Durability:
    The outer sheath features low adhesion and high tear resistance, ensuring long-term stable performance in applications involving frequent movement.
