CR gantry crane drum composite cable

CR gantry crane drum composite cableSpecially designed for heavy mobile equipment such as port gantry cranes (gantry cranes), suitable for high dynamic working conditions where the drum is frequently retracted and retracted, withexcellentThe tensile, wear-resistant, and flexural properties ensure long-term stable operation in harsh environments.

Main functions:

Its core function is to ensure stable power supply during dynamic movement, while resisting mechanical stress, wear, and corrosion, thereby extending the service life of the equipment and improving safety performance.

Here is a detailed analysis:

‌Tensile and wear-resistant designThe cable adopts a double-layer sheath structure, with the outer layer made of imported polyurethane (PUR) material, which is oil resistant, corrosion-resistant, and UV resistant; The inner layer is reinforced by aramid fiber weaving, providing tensile and torsional resistance to prevent internal structural damage during winding.

‌Dynamic adaptabilityThe conductor adopts multiple strands of ultra-fine oxygen free copper wire twisted, optimizing the twisted pitch to reduce bending stress, ensuring flexibility and fatigue resistance under high-frequency winding.

‌environmental toleranceThe working temperature range is usually between -30 ℃ and 90 ℃, which can adapt toharshClimate; The sheath material has waterproof and chemical corrosion resistance characteristics, suitable for outdoor or industrial polluted environments.

‌Safe and DurableCompliant with international flame retardant standards (such as IEC 60332-1-2), the outer sheath is designed to prevent cracking due to aging, and the service life is significantly longer than that of ordinary cables.
