2019 Magnum Attachments Hydraulic Breaker RHB 304-6 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.
Through Bolt
  • Designed to reduce internal stresses between powercell components resulting in a longer service life.
Nitrogen Gas Chamber
  • Compressed nitrogen gas provides energy to the cylinder downstroke resulting in less demand to the carrier's hydraulic system.
Integrated Valve Design
  • Integrated Valves on all hammer models provide better durability and performance by reducing the number of parts and minimizing pressure losses through external valves.
Light-Weight Cover
  • Reduces noise and provides dust protection
Lubrication Port
  • Compatible with automatic lubrication systems to ensure the chisel and bushing area are adequately greased.
Enclosed Box Design
  • The full box enclosure protects the powercell minimizing hammer maintenance and reduces noise. Standard on all models
Piston
  • Long piston stroke minimizes recoil, reduces vibration and provides greater impact energy
Wear Plates
  • As many as eight abrasion resistant wear plates maintain the position of the powercell within the box while reducing noise and vibra
Tool Retaining Bars
  • 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 Rock Claw
  • Hardened steel for maximum service life designed to assist the positioning of material to be broken. Quarry Box Design — on Models 313-350.
High Quality Working Tool
  • High grade heat treated steel.
