Application
Our milling excavator picks are engineered for installation on milling excavating equipment such as hydraulic drum cutters, roadheaders, and trenching machines, used for precise rock excavation, tunnel profiling, and surface demolition. They offer broad compatibility with leading global brands, including Erkat, Epiroc, Simex, Kemroc, CAT, and JCB.
These picks are extensively utilized across a wide range of rotary excavating engineering applications, such as:
Trenching: High-precision cutting for narrow utility pipelines, communication cables, and drainage networks.
Demolition: Breaking down reinforced concrete structures, bridge decks, and building foundations with low vibration.
Mining & Quarrying: Primary extraction of medium-hard minerals and cleaning of rock faces in open-cast mines.
Underwater Excavation: Precise deepening of canals and harbor basins where traditional blasting is prohibited.
Tunnelling: Efficiently profiling tunnel arches and excavating hard rock faces in subway or highway tunnels.
Product Composition & Technology
The Hengpu series milling excavator picks integrate a premium tungsten carbide alloy tip with a high-strength 42CrMo steel shank, which undergoes a quenching process for superior durability. Our patented innovation lies in the 3D laser-printed ceramic wear-resistant layer.
Advanced Material: Achieving a remarkable hardness of 68-70 HRC.
Superior Bonding: Utilizing a breakthrough metal-ceramic atomic bonding technology, the layer forms an exceptionally tight bond between the tip and shank. This significantly reduces wear at the critical junction point.
Enhanced Durability: The wear-resistant layer excels on hard geology, offering outstanding abrasion resistance.
By increasing excavating depth while reducing the frequency of tooth replacements, the Hengpu series minimizes labor costs and machine downtime, ultimately maximizing project efficiency and lowering total operating expenses.
3D Laser Ceramic Printed Wear Layer – Industrial Wear Technology Expert
Hengpu is a pioneer in industrial wear resistance technology. We have overcome the long-standing industry challenge of balancing extreme hardness with exceptional toughness.
Technical Breakthrough: Our proprietary process solves the interface bonding difficulties between ceramic particles and the metal matrix. This enables 3D printing of wear layers using over ten types of ceramics (including Al₂O₃, ZrO₂, and SiC) with thicknesses up to 4mm.
Optimized Design: The laser-printed layer features 3D raised and recessed structures that ensure even surface wear distribution, precisely matching the designed service life.
Quality Assurance: The entire manufacturing process adheres to stringent international standards, with each tool certified under ISO9001:2008 and GJB9004B-2009 to guarantee stability and reliability.
Product Advantages
Innovative Bionic Design: Inspired by pangolin scales, our proprietary wear-resistant technology creates a bionic structure where the ceramic layer fuses deeply (≥1mm) with the substrate. This represents a significant leap forward in material science.
Perfect Hardness-Toughness Balance: The atomic bonding technique merges the hardness of ceramics with the toughness of metal, delivering unparalleled performance, especially on hard geology.
Customizable Solutions: Available in various models (e.g., HPS120B-17TD, HPS120B-19TD, HPS120B-22TD, HPXW24B-13TD, HPXW24B-17TD, HPC31-17TD) with handle diameters of 30mm,24mm and 25mm. Custom lengths are available to meet specific equipment requirements.
High-Temperature & Abrasion Resistance: The laser-printed ceramic layer withstands high temperatures and severe abrasion, extending tool life and ensuring superior performance in the most demanding construction environments.
Rapid & Reliable Supply: Manufactured in mature industrial workshop systems to ensure fast delivery without compromising on strict quality control.
