Product Description

Montabert’s medium/heavy hydraulic breakers have patented designs which offer high quality, high productivity and an unbeatable robustness.


Montabert Medium/Heavy Hydraulic Rock Breakers Protect Your Investment

Maximum protection of the excavator thanks to its patented mechanisms. High resale value due to the longevity and reliability for which Montabert products are famous.
Power and versatility: whether you are breaking rock or concrete, or are excavating, Montabert hydraulic breakers guarantee optimum performance for all your projects.
The choice of a Montabert heavy hydraulic breaker is an investment which will maximize the profitability of your work.
The medium range of breakers with 1 speed (501 NG, 700 and 900) covers all excavators between 8 and 25 tonnes in weight, offering reliability and solutions to the customer’s needs.
The heavy range is designed to be used on excavators over 18 tonnes, for demolition work, in mines, pits and for tunnel excavation as well as public works.


This range offers the choice between two patented systems which guarantee high productivity:

a system with 15 variable speeds (BRV system) which automatically adjusts to the ground conditions.
a system with two automatic speeds (V1200, V1800, V2500, V3500 and V4500), ideal to break up homogeneous materials.
Their reliable design ensures downtime is kept to a minimum , thus minimizing operational costs and lengthening the lifespan of the breaker and the excavator.



The very favourable weight/power ratio obtained through the use of special steels enables the maximum productivity.
Constant power regardless of the hydraulic conditions (temperature, viscosity, …) thanks to the automatic pressure regulator.
An energy recovery device enables the recycling of rebound energy, transmitting it to the following blow and thus increasing the power of the blow.


Save operating costs

Because of the high productivity and the optimized hydraulic efficiency of Montabert medium/heavy hydraulic breakers, the energy of the excavator is better converted into shock waves than with breakers using less advanced technology, hence there is a significant saving of fuel.
Montabert’s high standard of reliability for all heavy hydraulic rock breakers reduces downtime.



Superior reliability thanks to the choice of steel and the manufacturing quality of Montabert.
Blank fire protection: Energy chamber with diaphragm reduces the pressure variations in the hydraulic circuits in order to supply a high constant energy to the hydraulic breaker.
Heavy duty casing reduces noise and protects the hydraulic breaker from dust and foreign objects. From the V45 upwards, the breaker case incorporates a cast
bottom. This significantly increases resistance to wear compared to a traditional casing fabricated from steel.
Protection against overflow and overpressure (patented).



Pressurization kit for underwater work.
Tunnel versions (V32/V45/V55).
Silent series versions, optionally available for M700/M900/V1200/V32.
