High Carbon Galvanized Steel Cable 7x7 6x19 FC IWRC 6x36 19x7 Trolleying Steel Wire Rope for Tower Crane
This high-performance steel wire rope is specifically engineered for tower crane trolleying and heavy-lift operations, combining premium high-carbon steel material with advanced galvanization technology and multiple flexible strand constructions. It is designed to withstand extreme loads, harsh outdoor conditions, and frequent mechanical stress, ensuring reliable performance and long service life in construction, infrastructure, and heavy-industry applications.
- High-Carbon Steel Base: Made from high-quality high-carbon steel wires (carbon content typically 0.45%-0.95%), the rope delivers exceptional tensile strength, impact resistance, and fatigue durability. It minimizes permanent elongation under heavy loads, maintaining structural stability even during repeated lifting and trolleying cycles.
- Hot-Dip Galvanization (HDG): The entire rope undergoes professional hot-dip galvanization, forming a uniform, dense zinc coating on the surface of each steel wire. This coating provides superior corrosion resistance against moisture, rain, humidity, and industrial fumes—critical for tower cranes operating outdoors or in harsh environments (e.g., coastal areas, construction sites with dust/chemicals).


We offer multiple strand/wire configurations to match different tower crane working conditions (e.g., load capacity, bending frequency, trolley speed). Each structure is precision-engineered for optimal balance of strength, flexibility, and wear resistance:
Tailored to the unique demands of tower crane trolleying and lifting:
- Trolleying Optimization: The rope’s surface smoothness (enhanced by galvanization and precision stranding) reduces friction between the rope and trolley sheaves, minimizing wear on both components and extending maintenance intervals.
- Safety & Reliability: Manufactured in compliance with international standards (e.g., ISO 3154, ASTM A475, DIN 3060) for steel wire ropes in cranes. Each rope undergoes strict quality testing (tensile strength, breaking load, corrosion resistance, and fatigue life) to ensure it meets or exceeds safety requirements for heavy lifting.
- Low Maintenance: The galvanized coating reduces rust and debris accumulation, while the robust core (FC/IWRC) prevents internal wire breakage. This lowers the need for frequent inspection and replacement, cutting operational costs.
- All products are produced in ISO 9001-certified facilities, with full traceability from raw material sourcing to final shipment.
- Available in custom diameters (typically 8mm-60mm) and lengths to match specific tower crane models (e.g., flat-top, luffing jib, hammerhead cranes).
- Optional value-added services: surface lubrication (for further reducing friction), custom labeling, and technical support for rope installation and maintenance.
This high carbon galvanized steel wire rope is the ideal choice for tower crane operators seeking durability, safety, and performance—whether for routine construction tasks or heavy-duty industrial lifting.
