Hydraulic Breaker

HKM RED LINE BREAKERS – R 350 M 

(Mining Series – Engineered for Extreme Duty) 

The HKM Red Line R 350 M is a mining-specialized heavy-duty hydraulic breaker designed for 40–55 ton class excavators. 
With its distinctive white-red housing and reinforced body structure, the R 350 M delivers maximum impact power and durability in the harshest excavation and mining environments. 

R 350 M: BUILT TO GO DEEP. ENGINEERED TO LAST. 

Operating at 130–150 bar pressure with 210–240 l/min oil flow, the R 350 M ensures continuous and efficient impact force, even in high-resistance materials. 
Weighing 3,750 kg and equipped with a 175 mm tool diameter, it’s built for deep quarrying, heavy rock breaking, and large-scale mining operations. 

The high-pressure diaphragm accumulator, mounted directly on the main valve block, guarantees powerful and reliable energy delivery throughout prolonged shifts. 
The nut-free tie rod system uses short rods directly fastened to the front head, absorbing vibration before it spreads, significantly extending spare part life and reducing maintenance costs. 

With a solid housing, dust protection, and integrated vibration/noise damping, the R 350 M offers operator comfort and internal durability. 
It can be customized with automatic lubrication, underwater kits, and mining-grade reinforced housing, making it the go-to breaker for operations in the deepest, most abrasive, and demanding conditions.
