Hydraulic Breakers
AST Series Hydraulic Breakers
High-performing Piston Design
Engineered striking‑surface geometry ensures balanced weight distribution, helping prevent one-side firing.
Vibration Damper System
Additional side-ear dampers absorb vibration and provide structural support to the main body. AST130 & AST160 only
Optimized Seal Design
Designed to maximize seal life and reduce scratching.
Heavy-Duty Tool Retainer Pins and Front Tool Bushing
Ensure longer service life for key components.

- Higher Durability – reduces and wear and damage by only applying the power level required
- Increased Power – provide my more efficient hydraulic circuit
- Operator Convenience – eliminates the need to manually adjust the speed control
Signal Telemetry
- Monitor hydraulic breaker data and get notifications via Smart Phone, PC, or tablet.
- Track Location
- Monitor Operating Hours
- Be notified of Maintenance & Service Intervals
Automatic Greasing System
- Breaker mounted, hydraulically driven grease pump, connected to dedicated pressure and return ports on the hydraulic breaker body
- 400 g (14 oz) Replaceable Grease Cartridge that can be replaced or can be refilled through a grease fitting
- Grease output adjusted for each model of AST Hydraulic Breaker, the unit is equipped with an adjustment screw

CX Series
Easy to Service
With fewer parts integrated into the design, servicing the hydraulic hammer is both easy and less expensive
Low Operating Cost
High flow rates and low operating pressures minimize heat generation and hydraulic shock loading for smooth operation and maximum service life for both the carrier and hydraulic rock breaker
Operate in Varying Rock Conditions
Anti-blank fire on/off selector allows you to alternate modes when working in varying conditions (CX8 only)
Reduce Noise Levels
Boxed housing keeps the noise levels down, essential in high-density population areas
Optimize Production
Breaker-mounted manual high/low stroke selector valve optimizes power and speed, giving you options
Configurations
Configured for today’s skid steers, mini excavators, and backhoes for efficient use of the carrier’s hydraulic circuit
 BX Series
Easy to Service
With fewer parts integrated into the design, servicing the hydraulic hammer is both easy and less expensive
Low Operating Cost
High flow rates and low operating pressures minimize heat generation and hydraulic shock loading for smooth operation and maximum service life for both the carrier and breaker
Operate in Varying Conditions
Anti-blank fire on/off selector (BX10 – BX30) allows you to alternate modes when working in varying rock conditions
Extreme Duty and Wear Bar Kit Option
The extreme duty and wear bar kit offers additional protection against the wear and tear of your hydraulic rock breaker with a factory application of cast abrasion strips and a wear-resistant plate with rock claws
Reduce Noise Levels
Boxed housing keeps the noise levels down, essential in high-density population areas
Optimize Production
Hydraulic rock breaker-mounted manual stroke selector valve optimizes power and speed, giving you options for different applications
Auto-grease Options
The auto-grease system keeps your tool lubricated without the hassle of stopping your production cycle flow while delivering just the right amount of grease when it’s needed most. The system installs directly on the breaker
BXR Series
Extreme Impact Energy
The extra-long stroke pressure-balanced piston, oil regeneration system, and button-nose piston design maximize the blow energy needed to break hard rock
Continuous Duty in Harsh Conditions
High-strength alloy plate steel with abrasion-resistant plate housing and heat-treated alloy pistons allows the rock breaker to withstand the harshest conditions
High Operating Efficiency
The oil regeneration system increases BPMs (Beats Per Minute) without decreasing energy in hard material applications
