On behalf of Ningbo Changshi Electric Power Machinery Manufacturing Limited, a prominent China manufacturer and global exporter, we are thrilled to introduce our pinnacle achievement in conductor stringing technology: the 30 Ton Hydraulic Conductor Puller. This monumental machine is meticulously engineered to address the most formidable demands of extreme-scale overhead transmission line (OHTL) stringing operations. It stands as the definitive solution for the largest, most complex, and strategically critical power infrastructure developments across the globe.

Product Features & Benefits:

The Ningbo Changshi 30 Ton Hydraulic Conductor Puller is designed for unparalleled strength, surgical precision, and relentless reliability. It ensures the seamless, precise, and unequivocally safe handling of the heaviest, largest-diameter, or multiple bundled conductors over exceptionally long spans and through the most challenging, remote terrains, safeguarding your invaluable assets.

  • Ultimate 30-Ton Pulling Capacity: Offers an astonishing 300 kN (30 Ton) of continuous pulling force, setting a new industry benchmark. This makes it the definitive solution for the heaviest conductors, record-breaking ultra-long distance pulls, and the most complex multi-bundled conductor stringing configurations in grand-scale, UHV (Ultra-High Voltage) transmission projects.

  • Next-Generation Hydraulic Precision: Equipped with a state-of-the-art, high-pressure closed hydraulic circuit, featuring premium-grade, globally recognized components (e.g., top-tier Rexroth, Sauer-Danfoss). This sophisticated system allows for infinitely variable speed control and ultra-precise, digitally monitored tension management, ensuring absolute control and eliminating any risk of conductor damage under the most extreme loads.

  • Engineered for Extreme Durability & Longevity: Constructed with an exceptionally reinforced, anti-corrosion treated heavy-duty steel chassis, oversized structural components, and superior-grade materials throughout. This machine is built for extreme resilience against continuous, high-intensity operations and the most severe environmental conditions, guaranteeing unparalleled operational life and maximum structural integrity.

  • Advanced Multi-Tiered Safety System: Incorporates a robust automatic spring-applied, hydraulic-released brake system for instantaneous and fail-safe braking. A comprehensive over-pulling protection system, an integrated multi-point emergency stop system, and sophisticated real-time diagnostic monitoring provide the highest possible level of safety for both highly skilled personnel and multi-million-dollar conductor assets.

  • Maximum Output Industrial Powerhouse: Driven by an exceptionally high-performance, water-cooled industrial diesel engine (e.g., top-tier Cummins, Deutz, Caterpillar equivalent), meticulously optimized for consistent, maximum power delivery, superior torque, and optimal fuel efficiency even during the most demanding, prolonged pulling tasks.

  • Intuitive & Comprehensive Operator Interface: Features an advanced, ergonomic control panel with large, crystal-clear digital instrumentation and integrated diagnostic displays for real-time monitoring of pulling force, speed, engine parameters, and critical system indicators. This empowers operators with unparalleled control and simplifies even the most complex operations.

Product Applications:

Our 30 Ton Hydraulic Conductor Puller is specifically designed and highly recommended for:

  • Ultra-High Voltage (UHV) transmission line Construction: The ultimate solution for handling the massive conductors and complex bundles required for 500kV, 750kV, 1000kV, and future higher voltage lines.

  • Complex Multi-Bundled Conductor Stringing: Efficiently and safely pulling intricate bundles of 6, 8, or more conductors simultaneously over challenging distances.

  • Extreme Long-Span Crossings: Ideal for critical pulling operations over vast distances such as major river crossings, deep valleys, high mountain passes, and dense urban environments where intermediate tension points are minimal.

  • Super Heavy-Duty Re-conductoring Projects: Replacing existing large-diameter conductors with new, heavier, or larger capacity ones in the most demanding and sensitive environments.

  • Global Large-Scale Infrastructure Projects: Providing robust and reliable performance for national grid expansions, international interconnections, and remote large-scale power infrastructure development.
