Why is Die DN hydraulic hammer so unique from other playerS?

Has this ever happened to you?

You are an earth mover and need a hydraulic hammer for your carrier, but with so many brands in the market, you are totally confused.

You ask a local dealer for advice, but there are too many options.

Everyone tells that their hydraulic hammers feature the best performance and easy maintenance, but the features are too hard to understand:

Electric frequency control device, super dust-free protection, auto greasing system, underwater operation, and anti-blank firing design.

These options seem impressive, but do you really need them all?

What if you just need to find a hammer with satisfying performance, stable quality, and cost efficiency?

Then this article is for you!

It will help you find the right hammer in terms of structure, function, price, and service.

Internal valve vs external valve structure

There are two main types of hydraulic breaker designs on the market: internal valve and external valve.

Internal valve

Der DN-Hydraulikhammer is an internal valve type.

The design is simple and smart, with only two moving parts and fewer components.

The control valve is installed inside the cylinder.

The biggest advantage of an internal valve is of niedrige Ausfallrate, einfache Wartung, and low cost.

Most small Und medium-sized breakers are internal types.

External valve

There are also excavator hammers that adopt an external valve design, Furukawa being a typical example.

These types of breakers are more complex in structure, with more components that cost more to repair.

But they also have their upsides.

The external valve provides more buffer to the hydraulic pressure, which cools down the oil flow and relieves the impact to the excavator.

All these factors are crucial to heavy–duty excavator hammers.

With an accumulator set up to further relieve oil pressure, both the hammer and the excavator are better protected from the high oil pressure.

That’s why most heavy-duty excavator hammers (over 50 tons) are external valve types.

Conclusion

Internal valve types have better performance for small and medium-sized breakers, while external valves are better for heavy-duty excavator hammers.

So if you are interested in buying a small or medium size hydraulic hammer, or if you want to find a rock breaker that is easy to maintain and has reliable performance, then the DEHN rock breaker is the right choice for you.

Simplicity vs multi-function

Simplicity is the ultimate sophistication.

While many companies are busy making big, overly complicated, and fancy-looking machines in order to maximize profit, we at DN are fulfilling our end users’ underlying request for a simple, reliable and cost-efficient hydraulic breaker.

Over our 20 years of experience, we have always followed our own path. When it comes to hydraulic solutions, there is a choice between complicated and simple.

Our approach has always been simple and reliable, focusing on core functions.

A hydraulic hammer is meant to break rocks, and that is what it should be designed for. It does not have to be equipped with electric devices just to seem “intelligent.” Nor does the user need to pay another $1000 for an “auto-greasing” system.

Zusätzliche Funktionen für einen Hydraulikhammer kosten nicht nur mehr Geld, sondern verursachen auch potenzielle Probleme während der langen Lebensdauer.

Multifunktionalität bedeutet zusätzliche Komponenten und ein komplexeres Design, was wiederum ein höheres Ausfallrisiko bedeutet.

The balance between simplicity and multi-function is hard to handle, but that is where DEHN breakers excel. We’ve invested our 20 years’ experience to come out with hydraulic hammers with outstanding cost performance in the market.

With comprehensive feedback and fast reaction to the market, we have satisfied thousands of clients with our “philosophy of simplicity.”

Der DEHN hydraulic hammer is your choice for best cost performance.
