Connection to Hydraulic Power Sources
The post driver can be connected to various hydraulic power sources, such as excavators,
trucks, loaders, tractors etc., and of course HYCON powerpacks, the design of which ensures
your new HYCON post driver the absolute best working conditions.
It is important that the post driver is not subjected to an oil flow and a working pressure
beyond its design capability. Please refer to the ID-tag on the post driver in case of doubt.
Check the oil flow and the working pressure by means of test equipment. The test
equipment should comprise a pressure gauge, a flow meter and a valve for adjustment of
the pressure.
Make sure that:
the oil flow is not too high
the working pressure is not too high
the return pressure is not too high
the pressure relief valve is not set higher than 160 bar
the internal diameter of the hoses is sufficient (min. ½”)
all couplings are clean
the power source is equipped with an oil filter of min. 25 Micron
Hoses with too small internal diameter and/or defect couplings cause the post driver to work
with incorrect working pressure. Your dealer can help you check this.
If the output of the power source is too high:
the power source must be adjusted to correct output
or you can choose to mount a HYCON oil flow divider to protect the post driver
against overload
or you can choose one of our HYCON powerpacks. Your dealer can guide you in
choosing the right powerpack.
In case of doubt, please contact your dealer or HYCON A/S.

NB. At service/repair it is important to mount the hoses correctly. The feed line from the power source must be mounted
at “P” and the return line at “T”. “P” and “T” are marked on the valve housing.
