ROCK BREAKER HIRE
DOWIN Rock Breakers
These rock breakers are made in South Korea using superior quality alloy steel that provides excellent durability.
The pressurized N2 gas in the main power cell allows operating with less demand on the base machine’s hydraulic power.
Fewer components
- DOWIN T series breakers are designed to harmonise the long piston stroke with the nitrogen cushion on the top of the piston, creating less shock and vibration than competing breakers.
- The Box Type breaker was developed to minimize noise during operation, with the use of sound-absorbing materials and a noise-reducing frame design; very useful for job sites in urban areas.
- Outstanding Power to Weight Ratio
- High Performance with Qualified Control Valve
