Working Principle & Advanced Technical Features

The HB20G adopts an advanced nitrogen-hydraulic composite power system, which is the core technology that sets it apart from standard hydraulic breakers.

1. Nitrogen Energy Storage & Recovery System

The rear chamber is filled with high-pressure nitrogen. During the piston’s upward stroke, nitrogen is compressed to store energy. During the downward stroke, hydraulic pressure and nitrogen expansion energy act simultaneously on the piston, significantly boosting impact energy and impact frequency. This design reduces hydraulic oil consumption, lowers heat generation, and protects the excavator’s hydraulic system.

2. Open Type Frame Structure

The open-frame design provides direct access to internal components for inspection, cleaning, and maintenance. It improves heat dissipation, reduces clogging from mud and debris, and enhances durability in harsh working conditions.

3. Optimized Hydraulic Control System

The precision-engineered hydraulic system ensures smooth oil flow, stable pressure, and consistent impact performance. It automatically adjusts impact frequency based on material hardness, preventing blank firing and reducing component wear.

4. High-Strength Alloy Steel Components

Key parts including the piston, cylinder, front head, tool bushing, and control valve are made from high-strength alloy steel (40CrMo, 42CrMo) through precision forging, heat treatment, and fine grinding. This ensures exceptional wear resistance, pressure resistance, and service life under heavy loads.

5. Anti-Blank Firing & Overload Protection

The built-in anti-blank firing system prevents piston damage when the chisel is not in contact with the material. Overload pressure protection avoids system failures caused by excessive pressure, improving safety and stability.

6. Easy Maintenance & Long Service Life

The modular design simplifies seal replacement, tool changes, and routine inspections. High-quality oil seals and wear parts extend service intervals and reduce downtime.

Core Product Advantages

1. Strong & Stable Breaking Power

With 3692 Joules of impact energy and an impact rate of 350–600 Bpm, the HB20G efficiently breaks reinforced concrete, asphalt, rock, and hardened soil. The nitrogen-assisted system ensures consistent power without hydraulic fluctuations.

2. Open Frame for Durability & Maintenance

The open structure reduces heat buildup, resists mud and dust, and allows quick maintenance. This lowers long-term operating costs and increases uptime.

3. Perfect Compatibility with 18–25 Ton Excavators

It fits all major excavator brands including CAT, Komatsu, Hitachi, Kobelco, Doosan, Hyundai, XCMG, SANY, and LiuGong. Installation and debugging are simple and fast.

4. High Efficiency & Energy Saving

The optimized hydraulic system matches the 125–160 l/min oil flow range of medium excavators, reducing fuel consumption while improving work efficiency by 20–30% in municipal and renovation projects.

5. Heavy-Duty Reliability

High-strength components, advanced heat treatment, and strict assembly standards ensure stable performance in harsh construction environments.

6. Safe & User-Friendly Design

Anti-blank firing, overload protection, and stable vibration control enhance safety for operators and equipment, especially in urban and confined spaces.
