Product Introduction
Application Areas
It is widely used in narrow trench excavation, demolition and reconstruction, mining, various engineering construction and metallurgical industries.
Advantages
▪ Its compact design, lacking a housing, makes it small, lightweight, and easy to operate. Furthermore, it’s 40% lighter than similar box-type hammers.
▪ Easy to transport and install, allowing for flexible operation in confined spaces.
▪ Optimized fluid dynamics improve structural strength, enhancing overall structural stability and reliability.
▪ No-load operation is possible, with high frequency and strong impact force.
▪ Equipped with a centralized lubrication system and an environmentally friendly channel with a water spray function, it reduces dust, is environmentally friendly, and saves energy.
▪ An additional oil drain port prevents false faults and facilitates maintenance.
