HKM G190 Hydraulic Breaker

HKM G190 Hydraulic Breaker

HKM Grey Line Medium Breakers offer the most efficient solution for the standard machines that carry the workload of construction sites.
The G190, one of the most popular models in the series, is designed to fully unleash the potential of 20–25 ton class excavators. It is neither too heavy to tire the excavator nor too light to compromise on performance; it offers a perfectly balanced power ratio.

G190: THE "ALL-ROUNDER" WARRIOR OF THE 20-TON CLASS

Hybrid piston technology sets the G190 apart from other breakers in its class. It combines hydraulic oil pressure with the explosive expansion power of nitrogen gas to drive the 140 mm diameter tool into the ground with immense speed.
This technology protects your machine's hydraulic pump while ensuring continuous breaking performance on hard rock and concrete grounds.

The Monoblock Body design eliminates the "tie-rod shearing" and "bolt loosening" problems that are the biggest enemies of breakers. This structure, with reduced parts and increased durability, lowers your maintenance costs.
Advanced noise and vibration insulation makes the G190 superior in terms of both operator comfort and environmental sensitivity.

G190 is a versatile power you can rely on in every project, from road construction to building demolition, quarry preparation to trench excavation.

Frequently Asked Questions (FAQ)

Q: Which tonnage excavators is the G190 ideal for?
A: The G190 is produced for machines between 18 and 26 tons. It gives the best performance especially on common 20, 22, and 24-ton excavators (e.g., 220, 240 series).

Q: What is the difference between G160 and G190?
A: The G190 is heavier (1830 kg) and has a thicker tool (140 mm). This allows for higher breaking power on harder grounds and larger machines compared to the G160.

Q: What is the advantage of the monoblock body?
A: The monoblock body eliminates the side tie-rods of the breaker. This design finishes the risk of tie-rod shearing under heavy working conditions and extends the life of the breaker.
