Son Amat needed a different material extraction solution due to the geographical location of the Balearic Islands and the problems associated with drilling and blasting in quarries. After thorough analysis, the seven-tonne Epiroc HB 7000 DP hydraulic breaker from specialist dealer COHIMAOP was chosen. The model was deemed the best option due to its flexibility and proven record of facilitating rapid and high production output.

"We were very careful when it came to putting together the right setup for this particular application, as we want to achieve the best possible result. The HB 7000 DP is impressive when dealing with the toughest rock and is undoubtedly the best tool for this project", says Manuel Morcillo, managing director of COHIMAOP.

Among other things, the HB 7000 DP hydraulic breaker opens up previously unused areas in Son Amat quarry. This is a major challenge that requires machines that can handle both limestone and its natural weathering.  The HB 7000 is said to have not disappointed and meets all expectations. It has a high impact force and the optimal per-minute impact rate, which increases productivity. It also works comparatively quietly and with low vibration levels.

The HB range of Epiroc hydraulic breaker offers models suitable for carriers from 22 to 140 tonnes. The exclusive Intelligent Protection System (IPS) – which combines Epiroc's well-known AutoControl and StartSelect functions – automatically adapts the working method of the breaker to any working conditions.

Thanks to the IPS system, the HB 7000 DP can be positioned in the fastest and most precise way. Ineffective blows, which could damage the attachment, can also be prevented. Thanks to the IPS system, which does not require any manual intervention, the operating time of the equipment is optimised, and there are no interruptions in the workflow.

Epiroc HB breakers include the Contilube II auto-greasing system, the PowerAdapt integrated pressure control valve, and the Vibrosilenced-Plus system, which reduces noise and vibration. The EnergyRecovery system also uses the recoil force of the piston for energy recovery. DustProtector II provides additional protection against dust and rock particles.

Son Amat is a significant aggregates supplier for the construction industry on Mallorca. The Son Amat quarry is located in the Porreras area, near Palma de Mallorca, and is one of the largest and most important on the island. Son Amat was founded in 1875, with the company's long history a clear indicator of its forward-looking management.
