Product Description
SB30 / GCB60 Hydraulic Breaker: Precision Performance for 4-7 Ton Excavators
Experience powerful precision with the SB30 / GCB60 Hydraulic Breaker. Designed for 4-7 ton excavators, it delivers superior efficiency and durability in demolition, trenching, rock breaking, and concrete recycling—perfect for professionals and rental fleets who demand results.
Advanced Engineering Features
Efficient Open-Type Structure
Designed with a classic open-body architecture, the SB30 / GCB60 ensures excellent heat dissipation, minimizes wear on internal components, and simplifies routine maintenance. The open-side construction allows rapid visual inspection and effortless cleaning of debris—keeping your equipment running longer with minimal downtime.
Smart Auto-Frequency Tuning Technology
Developed through Guchuan's proprietary R&D, the auto-frequency tuning system dynamically adjusts impact rate and striking power according to material hardness. This intelligent adaptation ensures optimal energy transfer, maximizing impact efficiency while reducing vibration and backpressure—protecting both your breaker and carrier from excessive stress.
Pure Hydraulic Power for Consistent Output
Unlike pneumatic or hybrid systems, the SB30 / GCB60 runs on pure hydraulic power, ensuring smooth, consistent force from your excavator's hydraulic system. The result: faster cycle times, improved fuel efficiency, and lower total operating costs—ideal for rental fleets and contractors demanding reliability on every job.
Optimized Integration with Your Excavator
Calibrated for 110-140 bar of pressure and 40-70 L/min of flow, the SB30 / GCB60 pairs perfectly with 4-7 ton excavators. This compatibility guarantees maximum productivity without overloading your machine—making it the ideal choice for operators searching for the best hydraulic breaker for 5-ton excavators or an efficient breaker for Kubota U35-class machines.

Superior Durability and Extended Service Life
Crafted with precision-machined components, a high-efficiency accumulator, and heat-treated alloy steel in critical wear zones such as the housing and bushings, the SB30 / GCB60 is built to perform under the toughest conditions. Its enhanced durability results in fewer breakdowns, lower maintenance costs, and a longer service lifespan.
High Efficiency and Reduced Operating Costs
Operating at up to 900 blows per minute, the SB30 / GCB60's optimized hydraulic system converts energy into impact with minimal loss—breaking more material in less time. This means lower fuel consumption and reduced labor hours, earning its reputation as a high-productivity mini excavator hammer trusted by professionals worldwide.
Versatile Across Applications
Featuring a 68mm chisel, this breaker is ideally suited for a wide variety of applications. From demolition, trenching, and rock excavation to asphalt, frost, and concrete breaking, the SB30 / GCB60 adapts to diverse working environments including construction, landscaping, utilities, and mining.
Simplified Maintenance and Global After-Sales Support
Engineered with serviceability in mind, the SB30 / GCB60 uses standardized tools and easily accessible spare parts, including compatible moil points and chisels. Backed by Guchuan's global supply network and responsive technical support, your operations stay efficient, wherever the job takes you.
