Why Choose the Rocka SK131?

Unrivaled Power: Higher Impact Energy, Less Downtime
The SK141 features an optimized hydraulic circuit and piston design, delivering an industry-leading impact energy of up to 8500 ft/lbs. This results in significantly more effective fragmentation per blow, reducing the number of strikes needed to break through material.

By shortening each work cycle, the SK131 enables higher daily production rates, allowing you to complete mining and demolition projects faster and more efficiently.

Engineered for Endurance: Reinforced Components Reduce Lifetime Cost
Addressing common industry failures like rapid chisel wear and lower cylinder cracking, the SK141 incorporates critical reinforcements. Its lower cylinder is forged from special alloy steel, and the piston surface undergoes super-hardening treatment. Coupled with an external automatic lubrication system, these features ensure optimal performance of core friction pairs, extending wear part life by up to 50%. This dramatically reduces your long-term maintenance and replacement part costs.

Intelligent Compatibility: Auto-Hydraulic Matching Protects Your Carrier & Maximizes Performance
The SK141 is equipped with an intelligent auto-hydraulic matching system. It automatically adapts to the hydraulic flow and pressure variations of different excavator brands This eliminates complex manual adjustments and effectively prevents issues like excavator hydraulic system overheating or reduced breaker efficiency due to flow mismatch. The system guarantees that both your carrier and the breaker operate at their 100% optimal capacity.

Application Scenarios: Built for the Most Demanding Conditions

• Granite / Basalt Quarries: Efficiently handles primary rock breaking and secondary reduction.

• Large Reinforced Concrete Demolition: Rapidly breaks down building foundations, bridge piers, and heavy industrial footings.

• Tunnel & Roadway Profiling: Provides precise and powerful force for contouring and finishing work.

• Port & Dock Pile Breaking: Its powerful impact force is designed to tackle weathered and robust concrete piles.
