A family‑owned quarry in Italy, famous for marble and granite extraction, faced a bottleneck. After blasting, oversized boulders remained that could not fit into their primary crusher. They had been using a rented hydraulic hammer, but the machine was unreliable, frequently leaking oil, and lacked sufficient impact energy for hard granite. The owner needed a permanent, durable solution.
He searched online for a rock breaker hammer that could work on his 25‑ton excavator. He also wanted a rock breaker for sale with good after‑sales support in Europe. After comparing several brands, he chose YG’s YG850 model.

How Did This Rock Breaker For Sale Performed In Granite?
The Italian quarry mounted the rock breaker for sale onto their 25‑ton excavator. The first test was on a 2‑meter granite boulder. Results were impressive:
- Penetration rate: The rock breaker hammer cracked the boulder into three pieces in under 90 seconds.
- Fuel efficiency: The excavator’s hydraulic system operated at a lower pressure than the rented hammer, saving 15% on fuel.
- Noise level: YG’s rock breaker hammer features a sound-suppression casing, keeping noise within Italian daytime noise limits.
The operator noted that the rock breaker for sale delivered consistent blow energy even at 800 bpm. The automatic lubrication system reduced daily maintenance time.
Customization For Italian Safety And Environmental Rules
YG engineers studied the quarry’s operating conditions: high altitude, cold winters, and strict EU noise regulations. Customizations included:
- Silenced version: The rock breaker hammer received additional sound‑absorbing foam inside the housing, reducing peak noise by 8 dB.
- Low‑temperature seals: All o‑rings and seals were upgraded for operation down to -10°C.
- CE certification mark: The rock breaker for sale came with full CE documentation required for Italian import.
- Quick‑change chisel system: The customer could swap between moil and blunt chisels in under five minutes.
For the rock breaker hammer, YG also provided an Italian‑language operation manual and spare parts list. The rock breaker for sale was painted in the quarry’s corporate orange color.
Tangible Results After Using The Rock Breaker Hammer
After two months of daily use (8 hours per day, five days per week), the Carrara quarry recorded measurable gains:
- Crusher feed rate increased by 35% because oversized boulders are now broken quickly.
- Downtime dropped from 3 hours per week (rented hammer repairs) to near zero.
- Operating cost reduced by 40% compared to the rental arrangement.
- Noise complaints from a nearby village stopped after the rock breaker hammer with silencing was deployed.
The rock breaker for sale paid for itself in just five months. The quarry owner has since ordered a smaller YG530 model for their 8‑ton excavator used in tight marble blocks.
