Redesigned Montabert Hydraulic Breakers

Montabert V1800 and V2500 Evolution hydraulic breakers feature an automatic two-speed variation system — adjusting impact energy and striking rate to deliver high energy per blow on hard ground and high frequency on soft ground — to improve productivity when processing homogeneous materials. The heavy-range hydraulic breakers have recently been redesigned to extend service life and reduce operating costs.

Operators can easily replace the lower bushing in the field without dismounting the breaker from the carrier. The two models also feature a modified lower suspension that extends the service life of the suspension system by reducing the wear on working parts.

An optional soft-start feature is available, allowing the breaker to deliver high frequency and low energy at the onset of operation. After a few seconds, the breaker resumes normal operation, delivering higher energy at a lower frequency.

Ideal for activities such as rock splitting and oversize breaking, the soft-start feature minimizes blank firing effects by creating a niche in the material for better positioning and energy transfer — preserving the breaker’s tool retainers and front guide. Standard features of the V1800 and V2500 include a blank-fire protection system that reduces harmful metal-to-metal contact and an energy recovery system that recycles recoil energy from the piston to increase strike power.

Working tools available for the V1800 and V2500 include a general purpose moil, a blunt tool and a chisel.
