40 Ton Hydraulic OHTLstringingequipment.com/Hydraulic-Conductor-Pullers.html target='_blank'>Conductor Puller: The Apex of Power for the World's Most Monumental OHTL Projects

On behalf of Ningbo Changshi Electric Power Machinery Manufacturing Limited, a prominent China manufacturer and global exporter renowned for cutting-edge tools and equipment for power lines, substations, and electrical construction, we are proud to unveil our unparalleled masterpiece: the 40 Ton Hydraulic Conductor Puller. This colossal machine sets a new global standard, meticulously engineered to command the most formidable demands of extreme-scale, long-distance, and complex overhead transmission line (OHTL) stringing operations. It is the definitive, indispensable asset for the largest, most challenging, and strategically critical power infrastructure developments across the globe.

Product Features & Benefits:

The Ningbo Changshi 40 Ton Hydraulic Conductor Puller is designed for unrivaled strength, surgical precision, and absolute unwavering 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 and ensuring project integrity.

Groundbreaking 40-Ton Pulling Capacity: Delivers an astonishing 400 kN (40 Ton) of continuous pulling force, establishing a new industry benchmark for extreme applications. This makes it the ultimate 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.
Supreme Hydraulic Precision & Control: Equipped with a state-of-the-art, ultra-high-pressure closed hydraulic circuit, featuring the highest-grade, globally recognized components (e.g., top-tier Rexroth, Bosch, Sauer-Danfoss). This sophisticated system allows for infinitesimally variable speed control and ultra-precise, digitally monitored tension management, ensuring absolute command and eliminating any risk of conductor damage under the most extreme loads.
Engineered for Unmatched Durability & Longevity: Constructed with an extraordinarily reinforced, anti-corrosion treated heavy-duty steel chassis, monumental structural components, and superior-grade, fatigue-resistant materials throughout. This machine is built for unprecedented resilience against continuous, peak-intensity operations and the most severe environmental conditions, guaranteeing unparalleled operational life and maximum structural integrity.
Advanced Redundant Safety System: Incorporates a robust, multi-layered automatic spring-applied, hydraulic-released brake system for instantaneous and fail-safe braking. A comprehensive, intelligent 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.
Hyper-Output Industrial Powerhouse: Driven by an exceptionally high-performance, water-cooled, heavy-duty industrial diesel engine (e.g., premium 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 Command Center: Features an advanced, ergonomic control panel with large, crystal-clear digital instrumentation, integrated diagnostic displays, and user-friendly HMI. This empowers operators with unparalleled control, simplifies complex operations, and enhances real-time decision-making.

Product Applications:

Our 40 Ton Hydraulic Conductor Puller is exclusively designed and highly recommended for:

Global Ultra-High Voltage (UHV) transmission line Construction: The ultimate solution for handling the largest conductors and most complex bundles required for 750kV, 1000kV, 1100kV, and future higher voltage lines.
Hyper-Complex Multi-Bundled conductor stringing: Efficiently and safely pulling intricate bundles of 8, 10, 12, or more conductors simultaneously over unprecedented distances.
Extreme Long-Span Crossings: Indispensable for critical pulling operations over vast distances such as major river crossings (e.g., Yangtze, Amazon), deep valleys, high mountain ranges (e.g., Himalayas, Andes), and highly congested urban environments where intermediate support points are virtually non-existent.
Record-Breaking Heavy-Duty Re-conductoring Projects: Replacing existing colossal-diameter conductors with new, even heavier, or larger capacity ones in the most demanding and sensitive environments.
International Mega-Infrastructure Projects: Providing robust, reliable, and unparalleled performance for national grid expansions, international power interconnections, and remote, large-scale power infrastructure developments in challenging territories.
