SB81 Hydraulic Breaker: High-Performance Rock Hammer for 18-26 Ton Excavators
Meta Description: Looking for a reliable SB81 hydraulic breaker? Our SB81 rock hammer offers superior impact power, high durability, and fits 18-26 ton excavators. Perfect for mining, demolition, and road construction
The SB81 Hydraulic Breaker is one of the most popular and versatile rock hammers in the construction and demolition industry. Engineered for heavy-duty performance, the SB81 model is specifically designed to fit 18-26 ton excavators, providing the perfect balance between impact energy and operational stability.
Whether you are tackling hard rock mining, reinforced concrete demolition, or road trenching, the SB81 ensures maximum productivity with minimal downtime.
The SB81 utilizes an advanced hydraulic-gas combined power system. By optimizing the nitrogen pressure, the breaker delivers a massive impact force that can crush the hardest granite and reinforced structures with ease.
High-Quality Alloy Steel: The main body and cylinder are forged from premium alloy steel, treated with specialized heat technology to prevent wear and cracking.
Reinforced Through-Bolts: Our SB81 features strengthened through-bolts that prevent breakages during high-intensity vibration.
With fewer internal moving parts and an optimized oil circuit design, the SB81 reduces hydraulic friction and heat generation, leading to lower fuel consumption for your excavator.
Available in both Side Type, Top Type, and Box (Silenced) Type to meet different project requirements and environmental regulations.
To help you choose the right equipment, here are the detailed technical parameters for the SB81 Rock Breaker:
