The following characteristics
contribute to making VISTARINI HPV hydraulic
breakers extremely productive
work tools:
• possibility of universal usage
• long life
• high performances
• high level reliability
• simple maintenance
• protection for the carrying machine
Numerous sophisticated details that have
been tested on the field (here illustrated
on a VH hydraulic hammer)
give our hydraulic hammers
a superior quality.
Vertical distributor protecting the
delivery and return oil pipes, can be
easily dismounted. The pressure seal cap
makes it easy to load the gas without
dismantling the pipes.
A -
Counter-pressure values
The hydraulic breaker is designed
to be able to work with very high
counter-pressure values. The
demolition performances are not
influenced up to counter-pressure
values of 27 kg/cm2. B - Compact dimensions
The bracket conformation has been
specially designed so that the
machine is particularly slim and
tapered. Moreover the hoses do not
protrude from the profile of the
breaker. C - No membranes
The particular energy recuperation
system, combined with the nitrogen
gas cycle system, has made it
possible to eliminate the
traditional rubber membrane, often
the cause of machine breakdowns. D - Extended piston
The extended design of the piston
guarantees excellent transfer of
the breaking wave for the whole
duration of the demolition cycle. E - Simple maintenance F - Energy recuperation
The nitrogen in the chamber of the
breaker抯 upper head is
compressed when the piston moves
upwards. In this way the energy
accumulated by the gas is
efficiently converted into blow
energy as the piston descends. The
result is an exceptional breaking
capacity which also contributes
effectively by acting as an inner
shock absorber, considerably
reducing the vibrations
transmitted to the excavator arm. G - Noise reduction
A silencing system has been used
to reduce the machine抯
noise level. Sound-proof chambers
have been created inside the
breaker and special buffers
outside deaden the resonances
produced by the bracket. H - Damping recoil for the
safety of the operator and the
machine
Obtained by the long piston
stroke. I - Long life of the
external structure
Guaranteed by the use of raw
materials that resist wear and
tear in the points subject to the
most intense stresses. L - Long life of the
bushings subject to wear and tear
The VISTARINI system provides
effective protection against dust. M - Reliable tools
High level performances and
reliability obtained as a result
of accurate scaling, the quality
of the steel used and the thermal
treatments carried out. N - Easy to extract the
pin
The tool locking pin is easy to
extract without having to use any
special tools
Vertical distributor
protecting the delivery and return
oil pipes, can be easily
dismounted
The pressure seal
cap makes it easy to load the gas
without dismantling the pipes
