9.3. Hydraulic pump unit for rotor drive
Order nr: 114151
The hydraulic pump unit for the rotor drive consist
of a tank, a gearbox with an hydraulic pump as well
as necessary valves.
The unit is mounted as in fig. At A there is already
provided holes for the mounting bolts in the
attachment frame.
The U-bolts B support the top part. The return hose
4 from the hydraulic motors are connected to the
fitting 4 on the return oil filter unit, the pressure pine
3 for the motors are correspondingly mounted to
the fitting 3 on the valve unit.
The speed regulation is done by the valve C (hand
wheel or screw), or by adjusting the PTO speed.
NOTICE
MAX 540 RPM ON THE PTO!!!
Do not use higher PTO speed than necessary to obtain wanted rotor
speed. High PTO speed increase un-necessary the heating of the oil.
Be careful to keep the telescope profiles of the drive shaft undamaged
and well lubricated. Jamming telescope profiles will rapidly damage the
drive shaft!
NOTICE
The return lines from the lifting cylinders and motor drain lines need to
be separated when mounting the hydraulic power unit.
