Explore our top-tier engineering solutions manufactured under strict OEM compliance for global road rehabilitation and civil infrastructure development.
Built upon groundbreaking academic research from Changan University since 1998, HEM Group and HME TOP Machinery lead the global sector in high-efficiency cold milling, asphalt recycling, and hydraulic power matching.
Founded in 1998 under the original title of Xi'an Hongda Communications Technology Co., Ltd. by esteemed professors from Changan University—Asia's premier institution for highway engineering and construction machinery design—HEM Group established the foundational standards for Chinese high-tech road equipment design.
Over more than two decades, our research engineers have pioneered scientific research achievements in mechanical dynamics, engine power matching, hydraulic transmission stability, and digital electro-proportional control systems. Recognized in 2006 as a official "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology, our cold milling machinery integrates structural rigidity with microscopic cutting precision.
Why global contractors and equipment fleets choose Chinese cold milling machine OEMs for unparalleled cost-efficiency, component durability, and vertical manufacturing integration.
Direct access to high-tensile structural steel alloys, tungsten carbide cutter tips, and heavy-duty casting facilities allows us to deliver ultra-durable milling drums at fraction of European manufacturing costs.
Whether configuring custom milling widths (from 0.5m micro-milling up to 2.2m full-depth surface extraction), engine tier compliance, or specialized track chassis, our engineering team executes seamless modification.
Our 5,000m² state-of-the-art production base leverages synchronized assembly lines, guaranteeing standard unit delivery within strict operational timelines to support rapid project deployment.
Evaluating long-term economic performance for international road maintenance enterprise buyers, municipal asset managers, and leasing companies.
For international fleet owners purchasing cold milling machines, capital expenditure (CapEx) is only one element of the equation. Operating expenses (OpEx)—driven by fuel consumption, tooth wear rate, conveyor belt longevity, and unscheduled downtime—determine true profitability.
HME TOP Machinery engineers machines designed specifically for maximum wear life. Our quick-change toolholder systems reduce tooth replacement downtime by 40%, while optimized cutter bit angles ensure maximum asphalt fracture efficiency with minimum dust generation.




From highway mainlines to urban micro-trenching, explore how modern milling innovations meet rigorous global engineering challenges.
High-speed full-width removal of rutted and damaged asphalt layers. Dual grade and slope electronic sensors ensure pinpoint leveling profile prior to fresh paving overlay.
Compact milling machines engineered for maneuverability around manhole covers, narrow municipal lanes, utility installations, and flush curb stripping without structural damage.
Precision fine-milling drums remove rubber deposits from airfield runways and strip thin-layer waterproof coatings on bridge decks with millimeter accuracy.
The road construction landscape is rapidly shifting toward digitized jobsite management and environmental sustainability. Emerging technology trends built into our latest OEM prototypes include:
Ensuring total operational confidence across borders through specialized export services, international engine compliance, and dedicated local technician hubs.
In 2017, HEM Group established HME TOP Machinery Equipment Co., Ltd. as its dedicated export and global service arm. We handle every phase of international transactions—from customs clearance, documentation, and maritime logistics to localized duty compliance.
Our equipment complies with global environmental standards, offering engine options compatible with Euro Stage V / US EPA Tier 4 Final emission norms, as well as robust Tier 2/3 variants designed for high-sulfur fuel regions.
