2019 Magnum Attachments Hydraulic Breaker RHB 303-6 Mini-Excavators
High frequency and high production hydraulic breakers designed specifically for mini-excavators and skid steers for light to medium breaking of rock and concrete.
These hammers are effective in a wide range of construction and demolition applications from breaking non-reinforced concrete with a RHB 303-6 or 304-6 on a mini-excavator to removing concrete sidewalks and pads with a RHB 305-6 on a skid steer.
These hammers have been designed to eliminate the unnecessary rubber bladder type accumulator, minimizing maintenance and downtime.
The 303-6, 304-6, and 305-6 are now designed as a silenced full box enclosure hammer.
Features may include:
Shock Mount- Heavy duty rubber shock mount absorbs power cell recoil minimizing machine wear and improves operator comfort.
- Designed to reduce internal stresses between powercell components resulting in a longer service life.
- Compressed nitrogen gas provides energy to the cylinder downstroke resulting in less demand to the carrier's hydraulic system.
- Integrated Valves on all hammer models provide better durability and performance by reducing the number of parts and minimizing pressure losses through external valves.
- Reduces noise and provides dust protection
- Compatible with automatic lubrication systems to ensure the chisel and bushing area are adequately greased.
- The full box enclosure protects the powercell minimizing hammer maintenance and reduces noise. Standard on all models
- Long piston stroke minimizes recoil, reduces vibration and provides greater impact energy
- As many as eight abrasion resistant wear plates maintain the position of the powercell within the box while reducing noise and vibra
- Allows for easy removal of tool. Dual retaining bars on Models 309-350. Tool Bushing — Field replaceable slip fit bushing, easy to replace resulting in reduced maintenance costs.
- Hardened steel for maximum service life designed to assist the positioning of material to be broken. Quarry Box Design — on Models 313-350.
- High grade heat treated steel.
