25 Ton Hydraulic OHTLstringingequipment.com/Hydraulic-Conductor-Pullers.html target='_blank'>Conductor Puller: Unrivaled Power for the World's Most Critical OHTL Projects

As a prominent China manufacturer and global exporter specializing in state-of-the-art tools and equipment for power lines, substations, and electrical construction, [Your Company Name] proudly presents our premier offering: the 25 Ton Hydraulic Conductor Puller. This colossal machine represents the absolute pinnacle of pulling technology, meticulously engineered to tackle the most formidable demands of extreme-duty overhead transmission line (OHTL) stringing operations. It is the indispensable asset for the largest, most complex, and critical power infrastructure developments across the globe.

Product Features & Benefits:

Our 25 Ton Hydraulic Conductor Puller is designed for unparalleled strength, surgical precision, and relentless reliability, ensuring the seamless and safe handling of the heaviest, largest-diameter, or multiple bundled conductors over exceptionally long spans and through the most challenging, remote terrains.

  • Unprecedented 25-Ton Pulling Capacity: Delivers an astonishing 250 kN (25 Ton) of continuous pulling force, making it the definitive solution for the heaviest conductors, record-breaking long-distance pulls, and the most complex multi-bundled conductor stringing configurations in grand-scale, ultra-high-voltage transmission projects.

  • Cutting-Edge Hydraulic Precision: Equipped with a state-of-the-art, high-pressure closed hydraulic circuit featuring premium-grade, globally sourced 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 preventing conductor damage under extreme loads.

  • Engineered for Extreme Durability: 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 invaluable 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 25 Ton Hydraulic Conductor Puller is specifically designed for:

  • Ultra-High Voltage (UHV) transmission line Construction: Handling the massive conductors required for 500kV, 750kV, 1000kV, and higher voltage lines.

  • Multi-Bundled conductor stringing: Efficiently pulling complex bundles of 4, 6, 8, or more conductors simultaneously.

  • Extreme Long-Span Crossings: Ideal for pulling conductors over vast distances, such as river crossings, mountain passes, and urban areas where intermediate tension points are limited.

  • Heavy-Duty Re-conductoring Projects: Replacing existing large-diameter conductors with new, heavier ones in challenging environments.

  • Complex Terrain Operations: Performing reliably in difficult, remote, or inaccessible locations where robustness and precision are paramount.
