Engineered for extreme performance, high durability, and maximum demolition efficiency. Explore our standard product range below.
In modern heavy engineering, mining exploration, and urban demolition, hydraulic rock breakers are pivotal in transforming raw horsepower into precise impact energy. As global infrastructure initiatives demand faster execution and tougher structural capabilities, the engineering specifications of excavator attachments have faced heightened scrutiny. Buyers globally seek manufacturers who balance robust metallurgy, micro-tolerance piston alignment, and intelligent hydraulic integration.
China has evolved from a mass-production hub to the epicenter of high-precision heavy machinery components. Key clusters in Shandong province, notably Yantai, host advanced industrial centers where companies utilize state-of-the-art heat treatment technology and robotic welding processes. When selecting a China Excavator Hydraulic Rock Breaker Supplier, leading global companies evaluate three core pillars: metallurgical longevity, hydraulic seal system reliability, and custom OEM manufacturing compliance.
Yantai Huida Intelligent Equipment Co., Ltd. was initially established in December 2016 and subsequently renamed on March 25, 2019, with a registered capital of 20 million yuan. Positioned as a premier research-oriented manufacturer in Yantai, the company specializes in scrap steel processing technology, automotive recycling machinery, renewable resource utilization systems, and high-performance excavator attachments.
With nearly 40 product invention patents and a robust intellectual property portfolio, Huida integrates advanced research, lean manufacturing processes, and rigorous testing methodologies. The comprehensive product lineup features state-of-the-art Eagle Hydraulic Shears, Double Cylinder Steel Shears, Hydraulic Car Scrap Shears, Concrete Crushers, Specialized Sorting Grabs, Quick Couplers, Heavy-Duty Lifting Electromagnet systems, Rippers, and advanced Top-Type/Box-Type Hydraulic Breakers.
Every piece of equipment undergoes a multi-phase quality assurance workflow, from raw material chemical testing to ultrasonic weld inspections and performance benchmarking under extreme hydraulic stress. This dedication is backed by our certified compliance with the ISO9001 Quality Management System.
Our Core Mission & Business Values
"Putting customers at the center and providing attentive service" represents our foundation and ongoing trajectory. Guided by the values of "innovation and efficiency, striving for excellence, and service first," our team is dedicated to designing products that match the longevity of your host excavator. We aim to secure our partners' operations, minimize unexpected downtime, and maximize investment returns across all demolition and excavation deployments.
Reliability in high-impact environments is driven by rigorous engineering design. The modern rock breaker operates via a complex oil-gas hybrid power cycles. To prevent hydraulic oil contamination and reduce recoil fatigue on excavator booms, Yantai Huida has integrated a series of engineering improvements:
We source heavy-gauge structural plates and high-grade chromium-molybdenum alloys. Components such as pistons, cylinder bodies, and front-heads undergo proprietary deep carburizing heat treatments to exceed HRC60 hardness standards, preventing micro-fissure expansion under stress.
Cylinder boring operations are performed in temperature-controlled CNC cells with tolerances held to < 0.005mm. This strict quality control prevents blow-by gases, minimizes internal friction, and maximizes hydraulic energy transfer efficiency to the chisel.
For custom systems, including electromagnetic lifting couplers and specialized shears, our manufacturing line integrates custom multi-layer control circuits (supporting 1 to 24 layers, with custom dimensions matching complex enclosures). This ensures telemetry feedback, real-time temperature sensing, and automated lubrication control.

Demolition and excavation attachments must adapt to varying environmental conditions. Yantai Huida’s engineering team configures product components for specific regional field conditions:
Our facility is situated in the Yantai industrial corridor, giving us direct access to high-quality steel mills, precision seal manufacturers, and local heat-treatment facilities. This regional advantage allows Yantai Huida to maintain competitive lead times and raw material quality control:
We manage all core processes—from alloy steel blank preparation, forging, precision CNC milling, and heat treatment to final quality testing—within our audited production areas. This localized workflow reduces logistics delays and minimizes assembly misalignments.
We work with established suppliers for critical wear parts, like Nok seal kits, high-strength piston rings, and impact chisel steels, ensuring consistent performance across batches.
With a 20-million-yuan capital base, advanced production bays, and nearly 50 skilled machinists, Yantai Huida can fulfill bulk dealer requests and custom OEM engineering orders on schedule.
Underpinned by the "Never give up" philosophy, our engineering division develops durable attachment designs.
Our team includes 6 specialist R&D engineers who develop customized attachment models using dynamic stress analysis and CAD modeling software, matching attachments to excavator operating weights and fluid flow requirements.
Nearly 50 skilled machining technicians operate our CNC machining lines. We implement strict quality, safety, and environmental protocols to ensure consistent production tolerances across all components.
We maintain active management plans for all raw materials. Our long-term partnerships with raw material suppliers ensure stable manufacturing timelines, even during periods of global supply chain volatility.
In addition to mechanical structural engineering, our advanced facility has capabilities to manufacture 1 to 24 layered printed circuit boards (PCBs). With a maximum board size of 16" x 26", this facility supports the production of customized electronic control modules, sensor integration, and telemetry systems for intelligent equipment lines. The standard manufacturing turnaround time depends on the complexity and quantity of the boards needed.
Our commitment to quality, environmental safety, and structural integrity is confirmed by recognized testing and certification bodies.

Answers to common questions regarding logistics, technical configuration, and custom OEM processes.
Matching is primarily determined by the operating weight of the host excavator and the hydraulic oil output parameters. The excavator's operating weight determines the payload stability of the boom. Using an oversized breaker can risk structural fatigue or tipping, while an undersized unit reduces work efficiency. Secondly, the hydraulic flow (L/min) and relief valve operating pressure (bar) must align with the breaker's operational specs to prevent overheating or piston seal failure.
Our chisels and internal pistons are forged from high-density alloy steel (40CrNiMo or 20CrNiMo equivalent). They undergo multi-stage deep carburizing heat treatment to achieve a surface hardness profile of HRC58-62, with core toughness maintained to withstand repeated mechanical shock.
Upon receiving client design criteria (such as specialized pins, dual-bracket linkages, or custom control wiring), our design team creates detailed 3D CAD configurations. We run finite element analysis (FEA) simulations to assess stress points before machining prototype units. Prototyping is followed by pressure cycle tests on our testing benches prior to final manufacturing approval.
The top-type breaker design offers a longer overall reach and is well-suited for high-angle quarry walls, trenching, and steep-slope demolition work. It provides direct downward force transfer from the excavator arm. For noise-restricted environments, we also offer box-type (silenced) models.
All heavy hydraulic units are thoroughly drained of residual testing oils, sealed with anti-corrosive industrial coatings, wrapped in protective barrier films, and secured in export-grade steel-framed wooden crates. This packaging prevents movement damage and moisture exposure during long ocean transit.
