Product Advantages

Why Choose Us: Premium Quality Hydraulic Breakers & Attachments

Our company is recognized in the industry for superior product quality, advanced manufacturing processes, and outstanding customer service. Here’s what sets our hydraulic breakers and excavator attachments apart:

1. Advanced Manufacturing Excellence

Forging vs. Cold Drawing: Most critical components, such as rod pins, are produced using forging techniques for enhanced strength, precision, and durability. We only use cold drawing for select models (HB20G, HB30G, SB121), always with the highest-grade materials.
Enhanced Functionality: We perform additional processes like chamfering and drilling lifting holes to improve usability and safety—steps often skipped by competitors.
Superior Heat Treatment: Our cylinders utilize CQT (Carburizing Heat Treatment), achieving a wear-resistant layer thickness of 1.5-1.7mm, far above the industry standard of 1.1-1.3mm. Precision grinding ensures a flawless finish and longer operational life.

2. Premium Raw Materials

We use only high-quality alloys, such as 20CrMo for medium cylinder forged parts, 20Cr2Ni4A/616V for high-strength pistons, and Q355 (22mm thickness) for shells—superior to the cast or scrap materials and Q235 steel commonly used in the market.
Our material choices not only enhance product longevity but also deliver higher cost-effectiveness in the long run.

3. Customization & Innovation

Our strong R&D capability allows us to provide custom hydraulic breakers and attachments tailored to your project requirements. OEM/ODM services ensure versatile solutions for various industries.

4. Quality Assurance & Exceptional After-Sales Service

Every product comes with a 1-year warranty, supported by a professional after-sales team.
We resolve claims within 8 hours, minimizing downtime and ensuring customer satisfaction.

5. Transparent Operations & Factory Visits

We welcome clients to visit our facilities, observe our advanced manufacturing processes, and witness our strict quality control measures firsthand.

Conclusion
Although our hydraulic breakers and attachments may come at a higher initial price, the investment is justified by:

Unmatched durability (forging, CQT heat treatment)
Superior materials (high-grade alloys)
Precision engineering (grinding, chamfering)
Reliable customization and fast after-sales support

Choose us for hydraulic breakers and excavator attachments that deliver long-term value, maximum performance, and peace of mind.
