MRX SERIES Rockbreaker System * complete system from smallest to largest appropriate hammer, including electric-hydraulic power pack and IQAN (can-bus) controls * less hammer ** swing pivot to dipper stick / hammer mounting pin (on-center) dimension FEATURES & BENEFITS High strength steel (bent, 4-plate) construction 65 ksi tensile strength; 50 ksi yield strength for longer service life Reinforced pivot and mounting pin joints from improved durability Hardened steel bushings in pivot joints and larger diameter pivot pins provide reduced bearing pressure and increased service life Excavator design hoist (inner) boom design for added strength and increased reach depth Sealed turn-table bearing and gear drive for longer service life Increased cross sectional strength of boom and dipper where high stress is realized Can-bus (IQAN) control technology for more precise control and metering for improved operation response Legend:

MRX Series Pedestal Rock Breaker System BOOM & HAMMER COMBINATIONS Hammer Specifications Hammer Models: Impact Energy Class: ft-lb (J) Impact Frequency bpm (short stroke) (*): BX & BXR hammers are furnished with a sound suppressing housing for superior noise attenuation. Noise levels may vary due to site conditions and barriers. Tool Selection (for aggregate production and mining) Concave Removal Tool For Gyratory Crusher • Blunt is used for boulder and oversize breaking; tool impact delivers the stress wave generated by the hammer causing the material to fracture; excellent wear resistance...
