Mini excavator weight is one of the essential factors you’ll need to consider if you plan on using one for your project. Although they are powerful enough to do many jobs, there’s no harm in finding the one that suits your needs best. Thus, here are the most frequently asked questions related to a mini

Investing in a mini excavator can be an excellent decision for construction or landscaping projects. Their compact size and maneuverability can help increase productivity and efficiency on the job site. The mini excavator price can vary depending on several factors, such as the brand, model, size, and features. These are the frequently asked questions about mini

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 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 low failure rate, easy maintenance, and low cost.   Most small and 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.

Hydraulic Breaker Hammer Working Principle A hydraulic breaker hammer is a type of construction machinery that is mounted on excavators, backhoes, skid steers, mini-excavators, and stationary plants. Driven by hydraulic power it breaks rocks into smaller sizes or demolishes concrete structures into manageable pieces. This engineering article classifies the hydraulic breaker hammer working principle,

What kind of after service do you expect when buying a machine? If you sell products for a living, you are going to lose, and that's just how it works. We know if we sell products for a living, we are going to lose. what we sell is "product+service”, it's always easy said than
