HB15G: High-Efficiency Open-Frame Hydraulic Hammer for 12-18 Ton Excavators

Product Overview

When the job demands relentless power and mechanical endurance, the HB15G (GCB180) stands as the industry standard for mid-sized excavators. Specifically engineered for the 12-18 ton carrier class, this breaker excels where standard attachments fail—delivering a high-energy impact of 2646 Joules to crush reinforced concrete and volcanic rock with ease.

Technical Parameter Reference

Engineering Excellence: The Guchuan Advantage

1. Specialized Open-Type "Top-Mount" Architecture

Unlike enclosed box types, the HB15G features a high-tensile open-frame design. This is preferred by many operators for three key reasons:

• Superior Thermal Management: The open structure allows for rapid heat dissipation during high-intensity 24/7 operations, preventing seal hardening and oil leaks.

• Rapid Field Maintenance: Every critical bolt and hose connection is easily accessible, reducing routine service time by up to 40%.

• Heavy-Duty Visibility: Provides the operator with a better line of sight for precision breaking in narrow trenches.

2. Intelligent Auto-Frequency Modulation

The HB15G isn't just strong; it's smart. Our Smart-Stroke Technology automatically senses material density:

• Hard Rock Mode: Delivers maximum impact energy at a lower frequency to penetrate deep into granite or bedrock.

• Concrete Mode: Increases the blow frequency for faster clearing of demolition debris.

• Result: This prevents "blank firing," significantly extending the lifespan of the piston and tie rods.

3. Pure Hydraulic Power Cell

While competitors rely heavily on high-pressure nitrogen gas (which fluctuates with temperature), the Guchuan GCB series utilizes a Hydraulic-Priority System. This ensures consistent striking force from the first minute of the shift to the last, regardless of the ambient climate.

Versatile Field Applications

• Infrastructure: Demolishing bridge piers, highway foundations, and heavy reinforced slabs.

• Mining & Quarrying: Primary breaking of oversized boulders and secondary reduction in gold or iron mines.

• Utility Trenching: Carving through hard-packed permafrost and rocky layers for large-scale pipeline installation.
