HPXdrive - Kinshofer

HPXdrive
Due to the fact that no operating cylinder is necessary, the unit is compact and
resistant against dirt, blows and uprising material from the grab.
The Revolutionary Drive Unit for Hydraulic Grabs
The rotation of the arms of the grab is generated by two hollow shafts, which run
opposed and have a helix thread, hydraulically driven by a single piston. The
shells are fixed to the shafts.
l Extending service life – up to 50% the drive unit runs in a permanent oil bath
- no lubrication necessary.
l Constant closing forces and optimal geometry of the shells allow easy digging,
even in compacted soils.
l The bucket shells are bolted to the shafts, and therefore it is very easy
to replace them with another set of shells. One HPXdrive can be used
for different applications which guarantees total versatility.
The HPXdrive is available for
l excavators up to 3t operating weight: D03HPX
l excavators up to 5t operating weight: C05HPX / D05HPX /
A05HPX / R05HPX
l excavators up to 8t operating weight: C08HPX / D09HPX /
A09HPX-HD / R08HPX
...all with exchangeable shells
Characteristics of the HPXdrive
Pressure Relief Valve
Two pressure relief valves protect the
grab against excessive operating pressure.
Therefore, the installation of extra valves
on the crane is no longer necessary, and
saves time and money.
Synchronization of Shells
As a result of having only one piston
the shafts run synchronically and
uniform. Compensation rods are
unnecessary.
Long Service Life
The outer surface of shafts and
piston are hardened through a
nitrate-coating, ensuring durability
and minimum wear and
tear.
Maintenance Free
The drive unit runs in a permanent oil bath
– no lubrication necessary. This saves time
and extends the service life.
Rotator and HPXdrive
Optimal Weight
The KM 04F140-30V hydraulic
rotator with continuous rotation
and the HPXdrive are integrated
in a single unit. Connecting
hoses are not necessary, therefore
no danger of leaks or breakage.
Hollow shafts and optimally sized parts
reduce overall weight.

Exchangeable Shells
The bucket shells of the HPXdrive are bolted to the shafts, and therefore it is very easy to replace them with another set of
shells. Different types of shells for different applications can be refitted onto the driving unit, e.g. clamshell bucket, rock
grab, timber grab, hay and forestry grab and multi purpose clamshell. Other types of shells are available on request.
The interchangeable shells are delivered with an exchange aid that guarantees that the HPXdrive can be positioned with ease.
Package: exchangeable shells, bolt-on teeth (for clamshell buckets), exchanging support

Characteristics of the HPXdrive
Synchronization of the Shells
Counterbalance Valve
The counterbalance valve grants the function
„Close“ and sustains the clamping force, if the
hydraulic pressure drops or fails. It protects the
drive from overstressing caused by external forces.
As a result of having only
one piston the shafts run
synchronically and uniform.
Compensation rods are
unnecessary.
Long Service Life
The outer surface of shafts and
piston are hardened through a
nitrate-coating, ensuring durability
and minimum wear and tear.
Rotator and HPXdrive
The flat hydraulic rotator with
continuous rotation by means
of two motors and the HPXdrive
are integrated in a single unit.
Eco-friendly: Connecting hoses
are not necessary, therefore no
danger of leaks or breakage.
Maintenance Free
The drive unit runs in a permanent oil bath
– no lubrication necessary. This saves time
and extends the service life.
