Features
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.
Pin On/Side Mount Style
Pin On/Side Mount style hammers provide more flexibility and are better suited for highway or construction breaking jobs. The reduced number of bolted joints also provides a more robust frame that increases hammer longevity.
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°.
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
