HKM RS300 Hydraulic Breaker

HKM RED LINE - RS300: THE PRODUCTION RATE THAT KEEPS A QUARRY MOVING

Engineered for Relentless Performance

HKM Red Line RS300 is purpose-built to deliver uninterrupted, high-impact performance for 33-45 ton class excavators.
Whether it's mining, heavy demolition, quarry operations, or large-scale infrastructure work - RS300 ensures maximum efficiency under extreme conditions.

RS300: BUILT FOR THE LONG SHIFT

With an operating pressure of 130-150 bar and oil flow of 170-250 l/min, the RS300 delivers smooth, high-performance impact energy in every strike.
Its 2,960 kg operating weight and 160 mm tool diameter make it a high-end solution for your toughest jobsite challenges.

The high-pressure accumulator, mounted on top of the main valve body, ensures reliable and consistent power across long operational hours.
Thanks to its nut-free, short tie rod system, vibration is absorbed before it spreads, eliminating fastener loosening issues and extending service life.

The solid housing design, with integrated dust, noise, and vibration protection, helps keep internal components safe while improving operator comfort.
With its superior strength and low maintenance needs, RS300 becomes the go-to tool for maximum uptime and productive performance.

Frequently Asked Questions (FAQ)

Q: What size excavator is the HKM RS300 compatible with?
A: The RS300 is designed for large-scale excavators ranging from 33 to 45 tons. It is an ideal attachment for quarries, mining, and heavy infrastructure projects.

Q: How does this breaker handle vibration in heavy-duty tasks?
A: The RS300 features a "Nut-Free Short Tie Rod" design and a vibration-damping system. These technologies absorb impact shock at the source, preventing damage to both the breaker and the carrier.

Q: Is it suitable for continuous mining operations?
A: Yes, with a weight of 2,960 kg and a solid, dust-protected housing, the RS300 is built specifically for the continuous and high-impact demands of mining environments.

Q: My fleet records list an HKM R300. Is the RS300 a different machine?
A: No, it is the same machine under a new name. The whole Red Line range moved from R to RS, so R300 is now RS300. Operating weight stays at 2960 kg, the tool diameter stays at 160 mm and the carrier range stays at 33-45 ton, so the bracket on your excavator still fits. Chisels, seal kits and all other spare parts ordered for the R300 are identical to the RS300 parts.
