Open Type Design Advantages

Superior Engineering for Demanding Applications

Superior Heat Dissipation: Open frame construction prevents overheating during extended operation
Enhanced Serviceability: Critical components accessible for minimal downtime maintenance
Robust Structural Integrity: Heavy-duty wear plates withstand extreme forces
Cost-Effective Operation: Simplified design reduces maintenance and parts replacement costs

Hydraulic-Nitrogen Operating Principle

The HB20G operates on a hydraulic-assisted nitrogen gas return mechanism for consistent performance across varying conditions.

Nitrogen Gas Advantages:

Consistent Impact Energy: Stable pressure across varying temperatures
Reduced Hydraulic Demand: Gas-assisted return improves system efficiency
Lower Operating Temperatures: Efficient energy transfer minimizes heat generation

Frequently Asked Questions

What excavator size is compatible with the HB20G?

The HB20G is designed for excavators in the 18-25 ton class, with optimal performance on 20-22 ton machines.

What materials can the HB20G break?

The HB20G effectively breaks medium-hard rocks including granite and limestone, reinforced concrete (C30-C50 grade), thick asphalt pavement, and industrial materials like slag and refractory.

What is the difference between open type and silent type breakers?

Open type breakers like the HB20G offer superior heat dissipation, easier maintenance access, and robust construction--ideal for heavy demolition and continuous operation. Silent type breakers incorporate noise-dampening enclosures for noise-sensitive environments.

What warranty does Guchuan Machinery provide?

We provide a 12-month warranty on hydraulic breakers and a 6-month warranty on spare parts, with comprehensive technical support throughout the product lifecycle.

Does Guchuan Machinery offer OEM services?

Yes, we offer comprehensive OEM and ODM services, manufacturing breakers to customer specifications with custom branding and packaging.
