Application

Cat® B Hammers are suitable for use 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.

Ergonomically Positioned Hydraulic Lines

Ergonomically positioned hydraulic lines are designed to optimize serviceability, are easily accessible and require no special tools. Housing has been positioned to protect against force and dirt during impact but allow for wrench access. Hydraulic lines and back head pressure can be checked and charged while breaker is mounted to machine, allowing quick monitoring of breaker's condition.

Gas Fired Design

Gas fired design delivers consistently high production over time making the breaker reliable in applications such as concrete, asphalt, rock and light trenching.

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.

Newly Designed Skid Steer Loader Mounting Bracket

Newly designed skid steer loader mounting bracket features enhanced hose routing and improved ingress/egress with new bolt-on step and updated central step. Brackets are compatible with H Model Hammers, E Series Hammers and the CVP16 and CVP40 Vibratory Plate Compactors.

Slip Fit Bushings

Slip fit bushings are field replaceable and easy to maintain due to one locking pin, extending wear life and reducing owning and operating costs. Upper bushing rotates 360°, lower bushing has two positions and can be rotated 90°.

Tool Mounted Operation and Maintenance Manual (OMM) Holder

Tool mounted OMM holder is sealed from the elements and includes all operation manuals and maintenance guides required for proper operation of the hammer (Skid Steer Loader bracket only).

Included with Each B Series Hammer

Every B Series Hammer comes with: Tool Kit w/Storage Box 2 Tools (1 x Conical and 1 x Transverse Chisel) Maintenance Kit
