30 Patents 
35 Trademarks 
36 Copyrights R&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, a leading level in the 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 shear lifespan 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 (P/H/M/DL/T/DT/DLT) and supports major brands such as Caterpillar, Komatsu, Hitachi, Sany, and XCMG.
Manufacturing Equipment
Precision Built. Systematically.
From German laser cutting (±0.1mm) to automated painting lines, every step of our manufacturing process 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; 45-day delivery from requirements assessment to prototype testing.
