It is hard to find a qualified heavy-duty rock breaker(over 50-ton class) at a reasonable rate.

The eligibility criteria are just too strict.

For instance, the Atlas Copco rock breaker adapts SCM420 alloy steel as cylinder material.

Its qualified hardness is 58-62 HRC, with carburizing thickness more than 2.5mm.

Moreover, the cylinder’s machining tolerance must be less than 0.1pm(0.0001mm).

There are no more than 3 domestic players who can meet the technical criteria of Atlas Copco.

In fact, 80% of 50-ton class rock breakers tend to damage within 3 months due to a piston or cylinder scratch.

We know who can handle it all well and can offer a true warranty of 1-year in the business.

The retail price is only around 50% of an Atlas Copco.

A heavy-duty rock breaker needs more attention than a small one.

In fact, at least 50% of damages result from improper operation.

It particularly occurs when installed for the first time. Here are several tips to follow.

1. We recommend charging and discharging the nitrogen at least 3 times before use. This way the nitrogen purity achieves nearly 99.99%.

2. Before installing a rock breaker, it is recommended to connect the breaker input and output hoses on the excavator’s forearm. Then start the carrier to circulate the hydraulic oil for about 30 minutes. This is to ensure the oil clean and can avoid possible piston and cylinder scratches.

3. Install the rock breaker on the boom, and then lightly strike the hammer vertically on soft ground for several minutes. This step is to exhaust air from hydraulic oil.

Finish the 3 steps, and your hammer is ready to go.

Those tips are not written in any troubleshooting books. We get those by years of practice and massive customer feedback. Talk to an expert.
