INTRODUCTION

Shanghai Deru Cable, China officially release the upgraded PUR Heavy Duty Crane Reeling Cable, a round copper torsion resistant cable specially engineered for rigorous industrial dynamic operation. Designed to serve mining facilities, port hoist equipment, and industrial conveyor systems, this heavy-duty reeling cable solves the long-standing pain points of traditional trailing cables, including torsion distortion, sheath abrasion, core fracture, and short service life under continuous winding, unwinding, and reciprocating dragging. With integrated round flexible structure, pure copper conductivity, and high-performance PUR protection, it has become a reliable power transmission solution for heavy-duty mobile industrial machinery.

Round Stranded Copper Conductor for Stable & Efficient Power Supply

This heavy-duty crane reeling cable adopts high-precision round stranded copper conductors with compact structural arrangement and excellent electrical conductivity. Different from flat cable structures, the round copper core design features uniform stress distribution, stronger bending resistance, and no internal wire dislocation during frequent reel movement. High-purity copper material ensures low resistivity, stable current transmission, and low power loss, supporting long-term continuous operation of high-load port hoists, mining lifting equipment, and automated conveyor systems.

The flexible stranding process greatly improves the cable’s anti-fatigue performance, enabling it to withstand tens of thousands of cyclic winding and trailing movements without core breakage, which fully meets the 24/7 continuous working requirements of industrial production and logistics transmission systems.

Heavy-Duty PUR Sheath for Harsh Industrial Environment Resistance

Built with premium industrial-grade PUR (Polyurethane) sheath, this crane reeling cable delivers far superior protection compared with ordinary PVC and rubber cables. The heavy-duty PUR outer layer features exceptional wear resistance, tear resistance, mechanical impact resistance, and structural stability, effectively resisting sharp friction, reel groove extrusion, and external collision during crane and conveyor equipment operation.

In addition to outstanding mechanical performance, the PUR sheath boasts excellent chemical resistance, including oil resistance, acid and alkali corrosion resistance, moisture proof, and salt fog resistance. It perfectly adapts to complex and harsh working scenarios, such as dusty and humid underground mining environments, corrosive coastal port terminals, and high-dust industrial conveyor operation workshops. The cable maintains stable flexibility and structural integrity within a wide temperature range of -40°C to 90°C, avoiding sheath hardening, cracking, and aging failure in extreme weather and working conditions.

Professional Torsion Resistant Structure for Dynamic Reeling Operation

Torsion failure is the main cause of premature damage for traditional crane drum cables. Our torsion resistant round reeling cable adopts an optimized internal cabling structure and reinforced anti-twist design, which can effectively offset torsion force generated during high-frequency rotation, winding, and unwinding.

This structural upgrade prevents cable twisting, knotting, core distortion and layered separation in long-term dynamic operation. It greatly reduces equipment downtime and cable replacement frequency, extending the overall service life by 3–5 times compared with conventional industrial reeling cables. The smooth round outer profile ensures flexible retraction and release on various crane reels and conveyor reel systems without jamming or deformation, guaranteeing uninterrupted power supply for mobile industrial equipment.
