Keep your operation running smoothly with the P&H dragline, designed from the ground up to provide long-term, consistent, and reliable performance, regardless of your specific requirements for boom length, bucket capacity, or geometry.
- The ultra-strong tub ensures the even distribution of loads, contributing to outstanding reliability.
- The A-frame is engineered to effectively manage and handle load forces.
- The four-chord boom is equipped with the structural integrity required to operate seamlessly in tough conditions.
- An electronics platform is integrated to assist operators in performing at peak efficiency.
Performance-Optimized Tub Design: Engineered for enduring performance, P&H tubs are constructed for long life and minimal maintenance. Handling multi-directional loads, the tubs feature verti-shield welding joins on all intersection plates, ensuring one continuous weld. This design minimizes distortion with widely distributed loading and maintains low residual stresses.
Productivity-Focused Intelligent Electronics: Efficiently monitor your machine’s performance to support seamless operation and maintenance activities. The Centurion control system incorporates intelligent electronics that actively track and analyze dragline operation, contributing to enhanced productivity.
Highly Engineered Boom and A-Frame: Experience stability and exceptional visibility with the highly engineered boom and A-frame design. The four-chord boom with a flat underside ensures balanced axial working loads and excellent visibility of boom point sheaves. The A-frame is specifically engineered to keep load forces low, especially for maximum-rated suspended loads.
User-Driven Engineering: Our equipment is designed with valuable input from users, focusing on advancements in safety, delivery, and solutions that streamline day-to-day maintenance and inspection activities. The ultimate goal is to assist you in achieving increased production, reduced downtime, and a lower cost per unit moved.
