Connection to Hydraulic Power Sources
The rock drill can be connected to various hydraulic power sources, such as excava-
tors, trucks, loaders, tractors etc., and of course HYCON powerpacks, the desi n of
which ensures your new HYCON rock drill the absolute best workin conditions.
It is important that the rock drill is not subjected to an oil flow and a workin pres-
sure beyond its desi n capability.
Check the oil flow and the workin pressure by means of test equipment. The test
equipment should comprise a pressure au e, a flow meter and a valve for adjust-
ment of pressure.
Make sure that:
•the oil supply is not too hi h
•the workin pressure is not too hi h
•the return pressure is not too hi h
•the pressure relief valve is not set hi her than 150 bar
•the internal diameter of the hoses is sufficient (min. ½”)
•all couplin s are clean
•the power source is equipped with an oil filter of min. 25 Micron
Hoses with too small internal diameter and/or defect couplin s cause the rock drill to
work with incorrect workin pressure.
Your dealer can help you check this.
If the output of the power source is too hi h:
•the power source must be adjusted to correct output
•or you can choose to mount a HYCON oil flow divider to protect the rock drill
a ainst overload
•or you can choose one of our HYCON powerpacks. Your dealer can uide you
in choosin the ri ht powerpack.
In case of doubt, please contact your dealer or HYCON A/S.
