HKM R300M Hydraulic Breaker

HKM R300M Mining Series Hydraulic Breaker

HKM RED LINE BREAKERS – R300M (Mining Series – Special Edition)

The HKM Red Line R300M is a mining-dedicated powerhouse designed to dominate in the most abrasive and demanding excavation environments.
Compatible with 33–45 ton class excavators, it features a reinforced white-red housing, a high-pressure accumulator, and a nut-free tie rod system, making it a top-tier choice for mining operations that require nonstop demolition performance.

R300M: BUILT FOR THE TOUGHEST MINING JOBS

Operating at 130–150 bar with an oil flow of 170–250 l/min, R 300 M maintains relentless power under extreme loads.
Its 2,960 kg weight and 160 mm tool diameter are engineered to break through the toughest rock and mineral layers with surgical precision.

Equipped with a high-pressure diaphragm accumulator, mounted directly on the main valve body, R 300 M guarantees consistent power delivery even during prolonged use.
The shortened nut-free tie rods, directly connected to the front head, effectively absorb early-stage vibrations — reducing structural fatigue and extending part life.

For mining-specific reliability, it includes a solid dust-sealed housing, noise and vibration dampening systems, and is optionally equipped with automatic lubrication, underwater kit, and a Flow Secure Valve for extreme fluid control.

The white and red color identity signals its place in the Mining Series, built to outperform and outlast under constant high-impact demands.
