As well as being efficient and reliable, Indeco
hydraulic hammers are now proving to be even
more environmentally-friendly and low on fuel
consumption. With a now even more efficient
hydraulic system |13|, the HP series has now also become
FS (Fuel Saving). Compared to other manufacturers’ models
of equivalent weight and performance, Indeco hammers
require less oil per minute and lower operating pressure.
And as using lower hydraulic power means reducing the
number of revolutions per minute on the carrier, they lead
to fuel savings o f up to 20%, while ensuring optimum
performance and maximum productivity. This becomes
even more evident when comparing the Indeco hammer
with gas or gas/oil powered products of similar size
manufactured by competitors.
The ABF (Anti Blank Firing) system |12|,
installed as standard on all of the medium- and
large-range Indeco hammers, cuts out blank
fire by eliminating any down pressure from
the hammer whenever the tool is not resting firmly on the
surface to be demolished.
This increases the service life of all components subject
to wear and tear, as well as reducing stress to the hammer
body and excavator arm.

Features of
Indeco hammers
All Indeco hammers have a special intelligent hydraulic
system |1|, enabling them to automatically vary the energy
and frequency of the blows according to the hardness of
the material being demolished.
This optimises the hydraulic pressure delivered by the
machine, thus improving productivity and enhancing the
overall performance.
Exclusive features such as the synchronised internal
distributor |2| aligned with the piston, the oil cushions |3|
for vibration dampening and the short hydraulic flow
pattern |4| make it possible to completely do away with
seals in the distribution area, a decisive factor in extending
the working life of the hammer and significantly reducing
downtimes.
The use of special low-alloy steels, exclusively manufactured
according to Indeco’s own formula greatly lengthen the
average working life of the major hammer components.
The housing |5| is made out of extra-strength HARDOX®
steel wear plates, which eliminate buckling.
The piston |6| is divided into two parts, for greater impact
energy and lower operating costs.
The centralised greasing system |7| enables the sliding parts
to remain lubricated even when the hammer is operating
horizontally, thus considerably reducing wear and tear on
components and extending product lifetime.
The “quick change” interchangeable bushing |8| is available
in various materials for different jobs; it is inserted into the
lower tool bushing where the tool moves, and reduces
maintenance times and costs, by cutting out the long
machine downtimes needed to replace the traditional fixed
bushing.
All carriers which mount Indeco hammers benefit from
the Indeco dual shock-absorption system |9|: an internal
hydraulic one and a mechanical one, located outside the
body, which substantially reduce the vibrations transmitted
to the excavator.
The excavator boom is also subject to lower stress levels,
as Indeco hammers are considerably lighter under working
conditions than rival makes in the same class. Alongside
the standard versions there is also a super-soundproofed
Whisper version, whose body is lined internally with sound-
absorbent material |10| and an “anti-rumble” paint, which –
combined with a few modifications to the bushing – enable
noise emission levels to be considerably reduced.
By lowering pressure peaks, the rechargeable hydraulic/
nitrogen accumulator |11| also reduces stress in the
excavator hydraulic circuit, keeps the gas charge
and energy per blow constant, and reduces maintenance
and operating costs.
