Although Indeco will remain specialists in the production and sales of hydraulic breakers, we are currently preparing to launch a range of new demolition products, such as crushers, grabs and grabbles. And that’s not all – pulverizers, compactors and telescopic handlers with the Indeco logo have been produced for several years, and imported on request to Australia and the rest of the world.

The intelligent system optimises the hydraulic pressure delivered by the machine, thus improving productivity and greatly enhancing the overall performance.

When purchasing a hydraulic breaker, you should follow a few basic principles:

• choose the right breaker for the type of job;
• evaluate any difficulties arising on site with a technician, and ensure that the machine is ready to be mounted with a breaker;
• choose a breaker which achieves a balance between the weight of the machine/weight of the breaker and between the power of the machine/power of the breaker;
• prevent excessive rebound vibrations to the boom by choosing a breaker with a suitable shock-absorption system;
• make sure that there is good after-sales assistance;
• evaluate the benefits of taking out a maintenance contract;
• find time to ensure that the breaker is taken out of use to have its first service (as specified in the “Instructions for use and maintenance” booklet, even if it appears to be working properly.
• Check in advance the availability and cost of spare parts

Pneumatic breakers have a gas chamber (usually pre-loaded nitrogen) which acts on the top part of the piston. The pressure of the gas increases when the piston moves up, pushed by the oil. This pressure then pushes the piston down until it hits the tool.

The biggest problem is the loss of nitrogen, which gradually reduces the pressure applied to the piston and consequently also the energy per blow. To resolve this problem therefore requires refilling the breaker with nitrogen. These breakers also age very quickly, as the main components wear out very quickly and tend to suffer from overheating. From a hydraulic point of view they are rigid, and they place enormous stress on an excavator’s telescopic handlers and roller bearings. They place great stress on the discharge and return tubes, and rapidly wear out the excavator’s pumps. Last but not least, their second-hand value is very low.

In hydraulic breakers, like the Indeco range, by contrast, the piston is lowered by the hydraulic pressure and “accelerated” by the oil-gas combination in the accumulator. This type of system has the following advantages :

• the gas charge and energy per blow can remain constant;
• less need for maintenance, resulting in lower costs;
• efficiency less affected by temperature changes;
• lower stress on excavator handlers and couplings due to hydraulic shock absorption;
• lower wear and tear on the discharge and return tubes.
• reduced component wear and high residual value of used breakers.

All Indeco breakers have an internal hydraulic system which provides high efficiency, which leads to a lower consumption of oil, thus lowering the fuel consumption of the excavator and less effort on the part of the machine’s hydraulic pumps.
The breaker is also equipped with a dual shock-absorption system, a hydraulic internal one and a mechanical external one, which reduces the stress transmitted to the excavator.

The centralised greasing system enables the sliding parts to remain lubricated even when the breaker is operating horizontally, thus considerably reducing wear and tear on components and extending product lifetime.

Alongside most standard versions is the Indeco WHISPER soundproofed version, the quietest breaker on the market.

Under working conditions, Indeco breakers weigh less than their counterparts in the same class (i.e. which have the same tool diameter), benefiting the machine as well as the excavator boom, which is thus subject to lower levels of stress.

Finally, Indeco have come up with a streamlined and well-proportioned structure which enables the user to work rationally even in difficult situations such as tunnels or deep narrow trenches.

Because it has a special hydraulic system which automatically regulates the energy and frequency of the hammer blows according to the type of material being demolished. This system, in our technical jargon, is known as Controlled Automatic Variance (C.A.V.).
