ARZ305 Monoblock Breaker: A New Standard in Hydraulic Excavation Tools
The ARZ305 Monoblock Breaker represents a cutting-edge solution for modern excavation and construction needs. Designed for excavators and carriers weighing between 4.5 and 9 tons, this breaker combines high impact performance with reliability and precision, making it an essential tool for demolition, trenching, and material breaking tasks. With a chisel diameter of 80 mm, it is engineered to deliver powerful and focused force to break concrete, rock, and other tough materials efficiently.
Powerful Performance and Technical Excellence
The ARZ305 operates with a working flow of 60–85 liters per minute and a working pressure of 100–150 bar, ensuring smooth and consistent hydraulic performance even in demanding applications. Its impact rate ranges from 600 to 1260 beats per minute, providing operators with the flexibility to adjust the breaker’s speed and force according to the material hardness and the task requirements. This wide operational range ensures versatility across a variety of construction and demolition scenarios.
Built for heavy-duty use, the breaker weighs 300 kg, striking a balance between durability and manageability for carriers in the 4.5–9 ton class. The auto start mode enhances operational efficiency by activating the breaker immediately upon contact with the work material, reducing operator fatigue and speeding up repetitive tasks.
Safety and Environmental Considerations
The ARZ305 Monoblock Breaker incorporates advanced hydraulic and pneumatic safety features. The accumulator pressure of 40–45 bar stabilizes the hydraulic system, while the water pressure of 4 bar and water consumption of ≤9 liters per minute provide effective dust suppression, keeping work sites cleaner and safer. Noise levels are maintained at 121 dB(A), which is competitive for equipment of this power class, helping operators manage auditory safety on construction sites.
Additionally, the breaker requires a low air pressure of 2 bar and an air flow of ≤0.73 m³/min, ensuring minimal auxiliary power consumption while maintaining precise and consistent operation. These parameters make the ARZ305 suitable for extended use under challenging conditions while minimizing environmental impact.
Versatility for Modern Construction Needs
The ARZ305 Monoblock Breaker is engineered to adapt to diverse construction scenarios. Its high performance allows for rapid breaking of concrete slabs, asphalt, and natural rock, while the adjustable impact rate gives operators control for delicate tasks requiring precision. This versatility makes it ideal for urban construction projects, roadwork, quarrying, and general demolition operations.
The compact design and operational simplicity of the ARZ305 allow for quick installation on compatible carriers, reducing downtime during equipment changes or maintenance. The breaker’s robust construction ensures long-term durability, while the combination of hydraulic and pneumatic systems ensures efficient energy use and reduced operational wear.
Operator Efficiency and Productivity
Operators benefit from the intuitive design and advanced functionality of the ARZ305. The auto start mode, combined with adjustable hydraulic settings, reduces repetitive strain and improves productivity. With impact rates capable of reaching up to 1260 bpm, the breaker can handle both heavy-duty demolition and lighter precision tasks with ease, making it a versatile tool for multi-purpose use on construction sites.
Maintenance is simplified by the Monoblock design, which integrates the breaker’s primary components into a single unit. This reduces the number of potential failure points, minimizes service requirements, and allows operators to focus on project progress rather than equipment downtime.
Conclusion: A Benchmark for Hydraulic Breakers
The ARZ305 Monoblock Breaker sets a new benchmark for hydraulic excavation tools. Its combination of high impact power, adjustable operational parameters, and advanced safety features makes it an indispensable attachment for modern construction, demolition, and quarrying projects. Designed for carriers ranging from 4.5 to 9 tons, it delivers the perfect balance between power, control, and durability.
From urban construction to heavy industrial demolition, the ARZ305 enhances operational efficiency, reduces downtime, and ensures that operators can tackle even the toughest materials safely and effectively. Its robust build, versatile performance, and operator-friendly features make the ARZ305 Monoblock Breaker a smart investment for contractors, construction companies, and equipment rental services seeking to maximize productivity and reliability on the job site.
With the ARZ305, companies gain a dependable and efficient hydraulic breaker capable of performing across a wide range of applications, helping to set new standards in modern excavation and demolition efficiency.
