Features
This heavy-duty box type hydraulic breakers for large excavators is designed specifically for large-scale projects. It combines cutting-edge fluid dynamics design with military-grade manufacturing processes, making it a core, profitable product with low failure rates and high returns.
Featuring a monocoque design with a triangular structure, the housing is forged from high-tensile alloy steel and precision-bored. This significantly enhances the BLT280’s resistance to twisting and its strength under lateral loads. During heavy-duty crushing operations with large excavators, the housing perfectly absorbs the reaction forces from the excavator’s boom, effectively protecting the internal components from deformation.
The optimized hydraulic circuit and nitrogen chamber design enable a synergistic output of “high flow + high pressure,” with an impact frequency of 60–90 bpm (compared to an industry average of 50–70 bpm for similar products). This means customers can process a greater volume of material per unit of time, making it particularly suitable for secondary crushing of hard rocks such as granite and basalt. Construction efficiency is significantly improved, and the payback period for end customers is reduced by 20%.
Large-diameter drill rods offer enhanced flexural strength, while the long-rod design allows for greater drilling depths. When combined, these features reduce drill rod wear by 40% when drilling through highly abrasive materials such as reinforced concrete and ore. Compared to standard drill rods, the replacement interval is extended to over 800 hours, which not only lowers dealers’ costs for selling wear parts but also improves customer satisfaction.
The internal oil passage design has been optimized to reduce heat generation caused by turbulence. Combined with a high-flow oil circulation rate of 550–650 L/min, this ensures that the oil temperature is consistently maintained between 60 and 70°C even in high-temperature environments of 35°C. This guarantees that performance does not degrade during extreme heat or under high-intensity operating conditions, maintains an availability rate of over 98%, and prevents project delays caused by equipment downtime.
The BLT280 is a heavy-duty demolition tool designed specifically for large-scale engineering projects. It is perfectly suited for 120-200 ton excavators and is widely used in the following fields:
Open-pit mining: Secondary crushing and splitting of hard rocks such as granite and iron ore.
Large-scale infrastructure projects: Construction of hydroelectric dam foundations, tunnel excavation, and rock breaking for foundations.
Metallurgy and cement industries: Removal of steelmaking slag and treatment of cement kiln caking.
Large-scale demolition: Breaking and demolition of reinforced concrete structures.

FAQ
If your engineering project is large-scale, involves complex operating conditions, and aims for long-term economic benefits, purchasing a heavy-duty hydraulic breaker is not only worthwhile but also a key investment in enhancing your company’s core capabilities and productivity.
High Efficiency Yields High Returns: Although the initial purchase cost of a heavy-duty hydraulic breaker is relatively high, it is equipped with a large-diameter chisel (the BLT280 features a Φ210mm chisel) that delivers immense impact energy. When tackling large-volume projects, its operational efficiency is unmatched by small and medium-sized breakers.
Ideal Alternative to Traditional Blasting: In “no-blasting” zones—such as urban areas, roadside locations, tunnels, or complex mining sites—blasting operations are restricted. Heavy-duty hydraulic breakers are currently the most efficient and direct mechanical alternative to blasting.
Enhanced Safety and Environmental Protection: Compared to blasting, mechanical breaking has a smaller impact on the surrounding environment. It eliminates safety risks and dust pollution caused by flying rocks and vibrations, better aligning with modern engineering safety and green construction standards.
Reduced Idle Time and Relocation Costs: For owners who already possess large excavators, equipping them with a heavy-duty breaker allows the machine to switch flexibly between excavation and breaking operations. This improves the host machine’s utilization rate and avoids waste caused by idle time.
