Boost Efficiency & Reduce Noise with the SB43 / GCB75 Triangle Side Type Hydraulic Breaker

SB43 / GCB75 triangle side Hydraulic Breaker.Engineered for 6 to 9-ton excavators, the GCB75 is designed as a high-performance, direct-fit alternative to models like the Soosan SB43. It combines robust impact energy with advanced noise-dampening technology, making it the intelligent choice for urban construction, road work, and any project where noise control is a priority.

The "Triangle Side-Type" Advantage: Engineering for a Quieter Worksite

What sets the GCB75 apart is its innovative triangle side type design. Unlike traditional open-sideplate breakers, – a powerhouse of engineering designed to deliver exceptional impact force, reliability, and efficiency in the most demanding conditions. Whether you're in construction, mining, or quarrying, this hydraulic hammer is built to outperform.

• High-Impact Performance: With a massive 1017 Joules of impact energy, the SB43/GCB75 delivers devastating blows to break through reinforced concrete, rock, and other tough materials with ease.

• Optimal Excavator Match: Specifically engineered for 6-9 ton excavators, this breaker ensures a perfect balance between carrier size and tool power, maximizing efficiency without overloading your machine.

• Superior Efficiency: An operating pressure range of 120-150 Bar and an oil flow requirement of 50-90 l/min mean it works in harmony with your excavator's hydraulic system, providing powerful strikes while maintaining fuel efficiency.

• Rapid Blow Frequency: An impact rate of 400-800 blows per minute (BPM) ensures continuous, fast-paced demolition, significantly reducing project time compared to slower models.

• Robust Build & Compatibility: Fitted with a durable 75mm tool diameter and 1/2-inch hydraulic hoses, it's built for longevity and can handle high-pressure operations day in and day out.

Core Technology & Performance Features

Powerful & Efficient Impact

With a formidable 1017 Joules of impact energy​ and a variable blow rate of 400-800 blows per minute (BPM), the GCB75 delivers a perfect balance of high-impact force and speed. This ensures efficient fragmentation of concrete, rock, and asphalt without overstressing your carrier excavator.

Advanced Pure Hydraulic & Auto-Frequency Control

Guchuan Machinery possesses independent R&D capabilities, a key advantage reflected in the GCB75. Our breakers utilize a 100% pure hydraulic system​ for smooth, consistent power. Furthermore, our advanced auto-frequency control​ technology intelligently adjusts the impact rate to match the breaking material. This "smart" operation maximizes energy transfer, improves efficiency, and reduces unnecessary wear and fuel consumption.

Built for Reliability & Easy Maintenance

Every component of the GCB75 is manufactured to the highest standards. From the high-strength, wear-resistant tool steel piston to the precision-machined housing, durability is paramount. The breaker is designed for easy servicing, with readily accessible parts to minimize downtime and ensure long-term, cost-effective operation.

Ideal Applications for the SB43 / GCB75

This versatile breaker is perfectly suited for a wide range of medium-duty demolition and construction tasks, including:

• Construction Demolition: Breaking concrete foundations, slabs, and walls.

• Road Work & Trenching: Rock breaking, asphalt removal, and creating trenches.

• Quarry & Mining: Secondary rock breaking and material size reduction.

• Landscaping: Boulder breaking and site preparation.

Why Choose Guchuan's GCB75 Over Other Brands?
