Hydraulic Breakers
Medium Breakers
Four models from SC50 to M900MS, built for 7 to 25 tonne excavators. Production demolition, quarrying, trenching and the steady-state rock breaking that fills most Australian site days.

Medium-class hydraulic breakers
Mid-class impact energy for the excavators that do the work. 7 to 25 tonne carriers across demolition, civil and quarrying.
Montabert's medium range bridges the compact SD line and the heavier V-series, putting serious impact energy in the hands of mid-class excavator operators. SC50 sits at the entry, M900 and M900MS top the range, with the 501 NG covering the busy middle ground. All four share Montabert's heavy-duty construction, automatic pressure adjustment and broad market-attachment compatibility, supported by Monty Products parts and service from Perth.
Four-Model Range
SC50, 501 NG, M900 and M900MS cover the mid-class, pick the breaker that matches your hydraulics rather than settling for what's on the shelf.
Built for Production
Made for sustained breaking on quarries, demolition and trenching jobs where uptime, impact energy and frequency all matter equally.
Reliable & Serviceable
Heavy-duty hydraulics, automatic pressure adjustment, broad attachment compatibility and parts ex Perth keep the M-series earning.

Where It Works
Common applications across Australian construction, demolition and civil sites.
Production demolition
Mid-rise structural demolition, slab removal and reinforced concrete on commercial and civil sites.
Quarry & rock breaking
Stockpile reduction, oversize boulder secondary breaking and quarry face work.
Trenching & utilities
Rock trenching for water, gas and conduits where the compact range no longer keeps up.
Foundations & footings
Heavy footings, pile caps and foundation breakouts on industrial and infrastructure builds.
Civil works
Road and rail formation, bridge abutments, kerb and channel demolition for council and DOT projects.
Mass rock reduction
Bulk earthworks where blasting is restricted and mechanical breaking is the only path forward.
