SEWOOMIC Triangle Type SB30 Hydraulic Breaker – Compact Nitrogen Rock Breaker for Mini Excavators

Introduction

In the modern construction and demolition industry, hydraulic breakers have become essential excavator attachments for breaking rock, concrete, and other hard materials. Among the various models available on the market, the SB30 hydraulic backhoe rock hammer is widely recognized as a compact and efficient rock-breaking solution for mini excavators.

The SEWOOMIC Triangle Type SB30 hydraulic backhoe rock hammer, developed by Guchuan Machinery, is designed for 2.5–4.5 ton excavators and offers a powerful combination of compact structure, reliable performance, and high cost efficiency. Built with advanced nitrogen-assisted impact technology, this breaker delivers strong impact force while maintaining excellent durability and operational stability.

As a professional hydraulic breaker manufacturer, SEWOOMIC provides high-quality breakers comparable to many global brands while offering better value for contractors and equipment distributors.

Overview of the SB30 Hydraulic Breaker

The SB30 nitrogen hydraulic breaker is a compact excavator attachment designed for light to medium-duty demolition tasks. It uses a gas-assisted hydraulic percussion system, which combines hydraulic oil pressure with nitrogen gas energy to generate powerful impact force.

Typical specifications of the SB30 breaker include:

These parameters allow the SB30 breaker to deliver efficient performance while remaining compatible with most mini excavators.

Key Features of the SEWOOMIC Triangle Type SB30 Breaker

1. High-Efficiency Nitrogen Impact System

The SEWOOMIC SB30 hydraulic breaker uses a nitrogen gas-assisted hydraulic system, which enhances the energy stored during piston movement and releases it during the impact stroke.

Advantages include:

• Higher impact power

• Reduced hydraulic load on the excavator

• Improved energy efficiency

Nitrogen-assisted breakers are widely used in construction equipment because they deliver stronger impact energy while maintaining lower operating costs.

2. Compact Triangle Structure

The triangle type housing design is one of the most popular structures for small hydraulic breakers.

Key benefits include:

• Simple and durable structure

• Easy installation and maintenance

• Lower manufacturing cost

• Lightweight design for mini excavators

This design also provides better visibility and maneuverability for operators working in confined spaces.

3. High Impact Frequency

With an impact rate of 500–1100 blows per minute, the SB30 breaker offers fast and efficient material breaking capability.

The high blow frequency makes it especially suitable for:

• Concrete demolition

• Brick and asphalt breaking

• Secondary rock breaking

This improves overall jobsite productivity.

4. Durable Structural Components

The SEWOOMIC SB30 hydraulic backhoe rock hammer is manufactured using high-strength alloy steel and advanced heat treatment technology.

Important components such as:

• piston

• cylinder

• through bolts

• bushings

are engineered for long service life even under demanding working conditions.

This ensures high reliability and reduces maintenance costs.

5. Easy Maintenance and Low Operating Cost

For contractors and equipment distributors, maintenance cost is an important factor when choosing a hydraulic breaker.

The SB30 breaker is designed with:

• minimal internal moving parts

• easy seal replacement

• convenient tool changing system

This simplifies maintenance and reduces downtime during operation.

Working Principle of the SB30 Hydraulic Breaker

The working principle of a nitrogen hydraulic breaker is based on converting hydraulic energy into kinetic impact energy.

The process typically includes the following stages:

1. Hydraulic Oil Input
   The excavator supplies high-pressure hydraulic oil to the breaker.

2. Piston Acceleration
   The hydraulic pressure moves the piston upward while compressing nitrogen gas.

3. Energy Storage
   The compressed nitrogen stores energy inside the accumulator chamber.

4. Impact Stroke
   The piston strikes the chisel, transferring energy to the material being broken.

5. Return Stroke
   The piston returns to its original position, preparing for the next impact cycle.

This process repeats hundreds of times per minute, enabling the breaker to efficiently fracture rock and concrete.

Compatible Carrier Machines

The SB30 hydraulic backhoe rock hammer is suitable for a wide range of compact construction equipment, including:

• Mini excavators (2.5 – 4.5 tons)

• Compact excavators

• Small construction carriers

Popular excavator brands compatible with this breaker include:

• Kubota

• Takeuchi

• Bobcat

• Cater pillar

• Komatsu

Because of its compact size, the SB30 breaker is particularly popular in urban construction projects where space is limited.

Typical Applications

The SB30 excavator hydraulic breaker is widely used across multiple industries.

Construction and Demolition

• Concrete breaking

• Building renovation

• Asphalt removal

Municipal Engineering

• Pipeline trench excavation

• Road repair projects

• Urban reconstruction
