HYDRAULIC VIBRAS
OPERATION
5. OPERATION
After having ensured the proper mechanical and hydraulic installation of the HVB
or HVD unit it is ready for use.
5.1. OPERATING HVB AND HVD UNITS
HVB and HVD units are typically controlled with a push button from the cabin.
1. Start the base machine and make sure the hydraulic system is operational
2. After system is operational the vibration is strated by pressing the activation
button. Vibration starts immediately
If HVD is installed as in picture 16 on page 26, vibras pressure line is installed in to
same pressure line with the tools cylinder, the HVD starts automatically when the
pressure has increased enough in the pressure line.
This might happen when e.g. a bucket is used to penetrate frozen ground. When
the bucket hits frozen spot on the ground and can’t penetrate the pressure rises
and the HVD starts to vibrate helping the bucket to get through. The vibration
stops when the bucket pierces the ground and pressure decreases in the cylinder.
