RQ Line Silenced Series
The RQ-series have been designed with many special features:
The advanced gas & oil percussion mechanism generates extra power by accumulated gas pressure which ensures a very reliable performance with a wide range of excavator pump conditions.
IPC & ABH System, Integrated Power Control & Anti-Blank Hammering System allows you to choose from 3 different modes.
The automatic anti blank hammering function (shut off) can be switched off or on. The operator can select the cor rect operating mode from high frequency with normal power to low frequency with extra power. With this advanced system, the operator may choose the correct mode in accordance with site requirements in a matter of minutes and with a minimum of hassle.
Auto shut-off & easy start function
Breaker operation can be automatically stopped in order to prevent consequential damage to the power cell due to the blank hammering. Especially in secondary breaking or when the operator is unskilled.
Breaker operation is easy to restart when soft pressure is applied to the chisel to the work surface.
Enhanced vibration dampening & sound suppression system
Meet strict noise regulations and allow more comfort for the operator.
Further features are standard connections for underwater operation and an automatic lubrication pump.
Power control & Anti blank hammering system
H – mode: Long stroke & Extra power, ABH is OFF
· Mode used for hard rock breaking such as primary breaking, trench works and foundation works where the rock condition is constant.
· Hammer can be started without applying contact pressure to the working tool.
L – mode: Short stroke & Maximum frequency, ABH is OFF
· Hammer can be started without applying contact pressure to the working tool.
· This mode is used for soft rock and semi-hard rock breaking.
· High impact frequency and normal power provides higher productivity and reduces strain on the hammer and the carrier.
X – mode: Long Stroke & Extra power, ABH is ON
· This mode is used for hard rock breaking such as primary breaking, trench work, and secondary reduction works, where the rock condition is not constant.
· In ABH (Anti-blank hammering) working mode, it switches off the hammer automatically and prevents the blank hammering, as soon as the material is broken.
· The hammer can be easily restarted when minimal contact pressure is applied to the working tool.
· The ABH system reduces strain on the hammer and the carrier.
