ARZ Series Hydraulic Breakers Win Strong Recognition in South America

South America, known for its vast and diverse mineral resources, has seen a rapidly increasing demand for efficient and durable drilling rigs in recent years. These rigs are essential in large-scale open-pit mining operations, undertaking critical auxiliary tasks such as slope clearing, bottom cleaning, and even secondary demolition. For these kind of secondary demolition jobs, special-customized hydraulic breaker will be needful.

After extensive research and testing, ANRV lanuched our ARZ sereis monoblock type breakers for these kind of secondary demolition jobs in the mining site.

1. ARZ series monoblock have been designed in 1 piece out case, the raw material hardness up to 58-62 HRC, significantly improves this series hammer's wear resistance. Which is prefectly fit the demolition jobs in mining condition. ANRV innovative use of new production and processing , ANRV call it HPGF. Under the premise of ensuring the hardness of the shell, the service life of ARZ breaker outcase is maximized, which is a perfect match for the harsh working conditions such as mining pits and tunnel caves.

2. Sometimes, the mining pit and tunnel cave sace is very narrow, so the small size breakers is better choice. Our ARZ305 monoblock breakers, only 300 kgs , and the out dimension is 1355mm*433mm*335mm, easy to get inside these narrow mining pits or tunnel caves. ARZ55, ARZ155,ARZ205 is smaller and lighter.

3. During to the demolition jobs demands, these jobs require the breaker can do different direction impact. the ARZ monoblock breakers have been designed with bevel impact function.

4. New deisgn bring the Blank impact function, that can gurrante the high impact force and frequence, which is much better than normal type hydraulic-Nitrogen breakers.

Monoblock type hydraulic breaker for these drilling rigs that deliver powerful performance and reliability. By integrating these solutions, mining operators are able to significantly boost productivity, reduce downtime, and achieve higher levels of efficiency in challenging environments. This commitment to innovation highlights ANRV’s goal of offering better hydraulic demolition breakers and advanced solutions tailored for the mining industry.

The ARZ series monoblock type hydraulic breakers represent a breakthrough in hammer design. Compact, lightweight, and versatile, they are perfectly suited for smaller drill rigs operating in confined or limited spaces, such as narrow mining tunnels or compact open-pit sections. Unlike many conventional models on the market, the ARZ series is capable of functioning in both open-pit and oblique directions, allowing for flexible adaptation to complex mine layouts and internal configurations. This design not only expands the operational scope but also ensures smoother transitions between different tasks, making the ARZ series an advanced hydraulic breakers for mining applications.

Given the harsh realities of mining and furnace environments, ANRV employs an integrated shell design that offers superior protection for the hammer’s internal core. This ensures durability against shocks, abrasions, and long hours of operation. Furthermore, ANRV has invested in advanced precision forging techniques and adopted tougher, more wear-resistant materials to extend the working life of the ARZ series. After undergoing deep cold treatment, the integral shell achieves a remarkable hardness rating of 58-62HRC, significantly enhancing wear resistance. These improvements translate into greater stability, minimized maintenance, and overall lower operating costs for the customer—making the ARZ series a benchmark in heavy duty hydraulic breakers.

For operations that require continuous, long-term crushing, ANRV has incorporated a water spray system into the ARZ hydraulic hammer. This feature reduces dust infiltration, protects internal components, and improves visibility of the working area—key elements for maintaining operator safety and efficiency in demanding conditions.

The reliability of the ARZ series has already been proven in the field. In May 2025, a South American customer procured one ARZ hammer as a trial sample. After three weeks of rigorous testing under actual mining conditions, the feedback from operators was overwhelmingly positive, with no reports of mechanical issues or operational difficulties.

ANRV has always believed that the market is the best teacher for its products. We are constantly attentive to customer needs and provide customized, differentiated products to maximize customer support.
