Heavy-class hydraulic breakers
Built for the hardest rock and the largest carriers. 20 to 80 tonne excavators across mining, quarrying and major demolition.
Montabert's heavy V-series is built for sustained production on the toughest jobs Australia throws at a breaker. The V1800 EVO and V2500 EVO bring updated hydraulics to the mid-heavy class, while the V3500 and V4700 cover the largest excavators most operators run. Two working positions on each model give a productivity-versus-precision trade-off without changing the breaker. Monty Products provides full parts, tooling and service support nationally from Perth.
Built for the Hardest Rock
High-grade French steel, sound-damped housings and the impact energy for sustained breaking through igneous, metamorphic rock and reinforced concrete.
Two Working Positions
Switch between productivity and precision modes on the same breaker. Match output to material and operator preference without changing equipment.
Service-Friendly Construction
Automatic lubrication, reduced-maintenance accumulators, sleeved cylinders and vibration-dampened housings for operator comfort and long service life.

Where It Works
Common applications across Australian construction, demolition and civil sites.
Quarrying & rock breaking
Primary rock reduction, oversize boulder breakdown and quarry face work where blasting can't reach.
Heavy demolition
High-rise structural demolition, bridge and major civil-works dismantling.
Surface mining
Stockpile reduction, secondary breaking and pit-floor work on metalliferous and coal operations.
Reinforced concrete
Heavy footings, pile caps and foundations on industrial and infrastructure projects.
Civil & infrastructure
Road and rail formation through hard ground, dam works, port and harbour construction.
Primary rock reduction
Mass excavation through hard rock where lighter breakers no longer make economic progress.

Frequently asked
Common questions about Heavy Breakers
- Which heavy-class Montabert breaker fits my carrier?
- The V1800 EVO suits 20 to 30 tonne excavators, V2500 EVO suits 25 to 35 tonne, V3500 suits 30 to 45 tonne and V4700 suits 38 to 55 tonne. For carriers above 50 tonnes, look at the XL Series. Send us your carrier model and we'll size from there.
- What is variable frequency and why does it matter?
- The V Series adjusts strike rate based on material resistance. On softer or fractured rock the breaker speeds up to maximise productivity; on dense rock it slows down to deliver maximum impact energy per blow. The result is materially better productivity than fixed-frequency breakers on mixed-material work.
- Can the V Series be used in mining?
- Yes. V1800 EVO through V4700 are widely used in iron ore, gold and copper operations across WA. For high-volume primary breaking on hard rock, the XL Series may be a better fit. We work with mining contractors directly on TCO modelling.
- How often do heavy breakers need rebuilding?
- Typical rebuild interval is 5,000 to 7,500 operating hours, depending on duty cycle and material. We perform full factory-spec rebuilds at our Malaga workshop and can quote with serial number lookup.
- Do you ship to mine sites?
- Yes. We deliver and commission heavy breakers across WA and the NT, including Pilbara, Kimberley and Goldfields mine sites. Field commissioning includes hydraulic flow and pressure verification before handover.
