30 Patents
35 Trademarks
36 CopyrightsR&D Capabilities
Leading R&D system and technology reserves
40 professional engineers covering fields such as hydraulic systems, structural mechanics, materials science, and industrial design.
R&D Platforms
Yantai City "One Enterprise, One Technology" R&D Center · Provincial-level Enterprise Technology Center.
R&D Investment
Annual R&D investment exceeds 6% of revenue, setting the standard for the china excavator shear industry.
Partner Institutions
Established industry-academia-research partnerships with numerous universities and research institutes.
Core technology
Built for the Toughest Demolition. Engineered to Last
6 proprietary technologies deliver 3–4× longer blade life, faster cycle times, and zero-compromise durability on every jobsite.
Hardox® Monoblock Blade Technology
Uses imported Swedish Hardox® steel; laser-cut and formed in a single piece (no welding or splicing required), extending the lifespan of our scrap shear blades by 3–4 times.
Alloy Steel Forged Pivot Pin
Forged and heat-treated 42CrMo alloy steel replaces traditional castings, delivering impact toughness exceeding 80 J/cm².
360° Rotary Motor System
Features imported (Finnish/Swiss) piston motors with built-in mechanical brakes; offers high torque, rapid rotation, and precise 360° positioning.
Inverted Cylinder Design
Protects the cylinder rod from damage caused by flying debris at the demolition site, extending seal lifespan by 200%.
Differential Acceleration Valve
Increases no-load stroke speed by nearly 50%, significantly shortening the opening/closing cycle and boosting hourly cutting frequency.
Quick-Coupler System
Compatible with all standard interfaces and delivering true oem excavator shear compatibility with major brands like Caterpillar, Komatsu, Hitachi, Sany, and XCMG.
Manufacturing Equipment
Precision Built. Systematically.
From German laser cutting (±0.1mm) to automated painting lines, every step inside our excavator shear factory is engineered for exact tolerances and consistent quality at scale.
Blanking Equipment: German TRUMPF Laser Cutting Machines | 3 units · Precision ±0.1mm.
Welding Equipment: Japanese OTC/Panasonic Robotic Automated Welding | 8 Welding Workstations.
Machining: CNC Boring Machines · Machining Centers · CNC Lathes | 20+ units · Precision ±0.01mm.
Heat Treatment: Vacuum heat treatment furnaces, carburizing furnaces, surface hardening equipment | 5 units.
Testing Equipment: Coordinate Measuring Machines (CMM) · Hydraulic Test Rigs · Fatigue Testing Systems | 10+ Units/Sets.
Spray Coating Line: Eco-friendly automatic spray painting and baking/curing line | 2 lines.
Innovation Direction
The Next Generation of Attachments Starts Here.
From AI-adaptive hydraulics to zero-emission compatibility — we're building the intelligent, lightweight, and electrified solutions your fleet will run on tomorrow.
Intelligent Attachments:Sensor integration, remote operation, automatic weighing, and self-adaptive hydraulic adjustment based on operating conditions.
Lightweight Design: Topology-optimized structures combined with high-strength aluminum alloy composites, reducing weight by 15%–25%.
Electrification: Zero-emission attachment systems compatible with electric excavators.
Customized Development: Solutions tailored to specific customer operating conditions, including customized demolition pulverizer and shear designs; 45-day delivery from requirements assessment to prototype testing.
