1. GENERAL

This manual contains general information about assembly, installation, operation
and maintenance of the DYNASET HVB Hydraulic Vibration Pump and DYNASET
HVD Hydraulic Directional Vibra.

ATTENTION!

Read this user manual before installation, use or maintenance of the HVB
and HVD to ensure proper handling, operation and maintenance right
from the beginning. Pay attention to warnings and safety instructions.
READ CHAPTER ”2. SAFETY” for more information.

HYDRAULIC VIBRAS

GENERAL

1.1. PRODUCT INFORMATION

DYNASET HVB Hydraulic Vibration Pump is connected to the base machines
hydraulic cylinder that operates the tool e.g. bucket. Activating HVB it creates
fast back-forth movement to the cylinder resulting vibration to the tool. HVBs can
create up to 30 Hz vibration. The Vibration power depends on the cylinders max.
power. HVB is a great for enhancing bucket emptying, increasing frozen ground
penetration, soil compacting and pile driving.

DYNASET HVD Hydraulic Directional Vibra is installed straigth to the tool e.g. to a
bucket. HVDs produce powerful directional vibration for buckets, street cleaning
units, soil compacting etc. HVD vibras create up to 70kN power with 35 Hz
frequence.

2. SAFETY

2.1. SAFETY PRECAUTIONS

ATTENTION!

Operators and maintenance personnel must always comply with local
safety regulations and precautions in order to close out the possibility of
damages and accidents.

The pressure in hydraulic circuit of HVB and HVD is considerably high. The technical
condition of your equipment and hydraulic system should be under constant
observation.

HYDRAULIC VIBRAS

SAFETY

WARNING

HIGH PRESSURE OIL!

Can cause severe injuries.
Always wear appropriate clothing
and safety equipment.

Couplings, valves and hoses should be maintained tight and clean to avoid
possible leakages of pressure and hot blowouts. Hydraulic leakages must be
rectified immediately to avoid user and bystander injuries.

In order to avoid possible accidents, it is not allowed to clean or inspect HVB or
HVD unit when hydraulic circuit is pressurized. Prior to any cleaning, inspection
and service, hydraulic system of your base machine must be stopped and hydraulic
circuit must be depressurized.

2.2. SAFETY EQUIPMENT

Always wear appropriate clothing and safety equipment such as safety goggles,
safety shoes and ear protection when operating the HVB or HVD unit.

Dynaset Oy | Menotie 3, 33470 Ylöjärvi | puh. 03 3488 200 | [e-mail] | www.dynaset.com

15

2.3. OPERATING SAFETY

When operating the HVB or HVD unit, beware of machinery parts warmed by hot
hydraulic oil.

RISK OF BURNS!

Parts of the unit, oil, and oil filler cap
can be hotter than 80 °C!

Wear personal safety equipment!

HYDRAULIC VIBRAS

SAFETY

WARNING

ATTENTION!

Do not exceed the maximum pressure, temperature and load.

2.4. MAINTENANCE SAFETY

ATTENTION

Installation and service of hydraulic equipment must be performed by
qualified and experienced personnel only.

NOTE!

When carrying out any maintenance to HVB or HVD unit, keep the
components of the system clean. This is important to ensure safe, reliable
and longlife operation of your equipment.

3. OPERATING PRINCIPLES

3.1. OPERATING DESCRIPTION

HVB

HVB hydraulic Vibration Pump increases and decreases the pressure in cylinders A
and B lines creating a small fast pace movement, vibration.

HYDRAULIC VIBRAS

OPERATING INSTRUCTIONS

Picture 8: Operating description of HVB

When the hydraulic flow is opened to the HVB (1) it starts to create pressure to one
of the cylinders hydraulic lines. At the same time the HVB decreases the pressure
same amount from the other cylinders hydraulic line.

The patented pump structure of HVB reverses piston movement when the piston
reaches the peak point and the pressure direction turns to opposite. This way the
cylinder moves back and forth (2) safely creating vibration to the tool it is attached.

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.

HYDRAULIC VIBRAS

OPERATION

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.

6. MAINTENANCE

DYNASET HVB and HVD units are low-maintenance units. Only normally wearing
parts and materials should be replaced either when necessary or in accordance
with a service program.

Prior to starting any maintenance or repair, ensure that the HVB or HVD unit is
completely depressurized.

6.1. MAINTENANCE INTERVAL

All maintenance must be complied with as they are scheduled in this manual.
The following table provides maintenance schedule for DYNASET HVB or HVD unit.

HYDRAULIC VIBRAS

MAINTENANCE

CHECK POINTS

Clean HVB / HVD unit x

Change sealings and pump uid valves x

6.2. HYDRAULIC FLUIDS

Wide range of standard hydraulic fluids can be used with DYNASET hydraulic
equipment. Depending on the operating temperature, following mineral hydraulic
oils are recommended:

Mineral hydraulic oil Operation temperature up to

ISO VG 32S 60 °C
ISO VG 46S 70 °C
ISO VG 68S 80 °C

NOTE!

Recommended oil viscosity is between 10 to 35 cSt when operating at
normal operating temperature.

After daily use Every 4000 hours or if

necessary

Synthetic and bio-oils can also be used if their viscosity characteristics and
lubricating efficiency are similar to the mineral oils.

Automatic transmission fluids and even engine oils can be used, provided that
they are allowed to be used in hydraulic system of your base machine.

For the hydraulic fluid change interval follow the base machine’s maintenance
instructions.

To use special hydraulic fluids with DYNASET equipment, please contact the
nearest DYNASET representative for more information.
