HKM RS350 Hydraulic Breaker

HKM RS350 Hydraulic Breaker

HKM RED LINE - RS350: BUILT FOR HARD ROCK AND DEEP FOUNDATIONS

Unstoppable in Heavy Duty Operations. Power that Goes Deep. Performance that Lasts.

The HKM Red Line RS350 is engineered to dominate the heaviest demolition jobs in mining, quarrying, and large-scale infrastructure projects.
Compatible with 40-55 ton class excavators, this model delivers massive impact power while maintaining a long service life even under the most punishing conditions.

RS350: THE FORMATION GIVES WAY FIRST

With an operating pressure of 130-150 bar and oil flow of 210-240 l/min, the RS350 delivers maximum performance without compromise.
Weighing 3,750 kg and equipped with a 175 mm tool diameter, it is built to crush the hardest materials efficiently and consistently.

The high-pressure accumulator, mounted directly above the main valve block, provides optimal energy delivery with every blow.
Its nut-free tie rod design uses shortened, directly tightened rods to absorb vibration before it spreads - minimizing mechanical stress, reducing downtime, and extending spare part life.

The solid housing, equipped with dust protection, vibration and noise absorption, ensures both internal durability and a more comfortable operating environment.
Customizable with optional features such as reinforced housing for abrasive conditions, underwater equipment, and automatic lubrication systems, the RS350 is ready for any mission - deep, harsh, or complex.

Frequently Asked Questions (FAQ)

Q: Can the RS350 break hard rock in quarries?
A: Absolutely. With a massive operating weight of 3,750 kg and a 175 mm tool diameter, the RS350 is specifically engineered for high-impact performance in marble and stone quarries.

Q: What size excavator is required?
A: The RS350 is designed for heavy-duty excavators in the 40 to 55-ton class, ensuring optimal balance and hydraulic flow.

Q: How does it handle abrasive mining environments?
A: The RS350 comes with a dust-protected solid housing as standard. For extreme conditions, we also offer an optional "Reinforced Housing" to further protect the breaker body from wear and tear.

Q: Has the R350 been replaced by a new model called RS350?
A: It has not been replaced. R350 and RS350 are the same breaker: the Red Line range simply switched from R codes to RS codes. The 3750 kg operating weight, the 175 mm tool diameter and the 40-55 ton carrier range are all unchanged, and the spare parts list did not move. Chisels, bushings, seal kits and tie rods bought for the R350 fit the RS350 exactly.
