Mounting Bracket Size


Used in a wide range of construction and light demolition applications - such as breaking concrete sidewalks and driveways, pavement, roads, masonry, site prep and landscaping, and breaking frozen ground for utility repairs.


Fully enclosed, silenced housing lowers overall noise level for a quieter, safer job site. Internal power cell is protected, designed and engineered to eliminate stress points.

Flat Top/Top-Mount Style

Flat top/top-mount style provides a larger work area and excellent operator visibility with a common footprint and hole pattern for optimum versatility. Top-mount style increases impact power by keeping breaker force and stick force in line. A top-mount bracket will transfer back significantly less recoil and bending stress into the end of the stick, resulting in reduced impact on machine structures. Full complement of mounting brackets is available to suite coupler or pin-on preference.

Auto Shut Off (ASO)

ASO instantly stops the piston when breaking through material, preventing blank firing, a key contributor to hammer wear. Internal stresses are reduced, hammer is protected regardless of operator skill level.

Tri-Suspension System

Tri-Suspension system comprises the suspension jacket, the upper and lower buffers. Suspension aligns power cell and gives manageable, smooth performance.

Standing Height Grease Point

Standing height grease point makes required maintenance comfortable and easy to perform.

Easy to Tune & Maintain

Gas ports and valves are easy to check and charge while hammer is mounted to machine.

Ports Positioned for Hose Protection

Improved routing protects against force and dirt during impact, eliminating downtime.

Hammer Tools

Tools are heat-treated, matched to piston diameter and provide optimum mass to deliver full blow energy.
