Product Description

Meta Description: Introducing the SB81 / GCB220 Silent-Type Hydraulic Breaker — a machine designed to provide elite breaking force of over 4,000 joules while significantly reducing noise pollution, making it the intelligent choice for urban and sensitive environment projects.

SB81 / GCB220 Silent-Type Hydraulic Breaker: High Power, Lower Noise for 18-26 Ton Excavators

Engineered for Power and Compliance: The Silent Advantage

The SB81 / GCB220 Silent-Type Breaker is engineered to tackle the most demanding rock breaking and heavy demolition tasks while addressing critical modern worksite requirements: noise control and operational sustainability.

Core Technology & Silent Design Principles:

Advanced Noise Reduction System: Unlike standard breakers, the SB81 integrates specialized noise-dampening technology. This includes a optimized shroud design, internal damping materials, and a precision-engineered impact mechanism that minimizes sound wave emission without sacrificing power, achieving a controlled noise level of 118 dB.
Intelligent Auto-Variable Frequency: Leveraging our in-house R&D expertise in auto-frequency conversion, this breaker intelligently adjusts its impact rate (350-500 BPM) based on real-time material hardness. This not only optimizes efficiency and protects the carrier from hydraulic shock but also contributes to a smoother, less erratic—and consequently quieter—operation cycle.
Hydraulic, High-Efficiency Design: Our 100% pure hydraulic system ensures consistent, powerful performance with superior energy transfer. The combination of 4,067 Joules of impact energy and optimized oil flow requirements ensures maximum force is delivered to the tool tip, translating to faster material fracture and higher productivity per fuel unit.
Robust Construction for Longevity: Designed for a 140mm tool diameter, it features heavy-duty, wear-resistant components. The silent-type housing protects internal mechanisms from debris while the hardened piston and front head are built to withstand continuous high-impact stress, ensuring durability and lower total cost of ownership.
