Engineered for maximum density, precise levelling, and unmatched reliability across global highways, airports, and urban municipal networks.
Bridging theoretical mechanical dynamics with world-class road building equipment.
Founded in 1998 as Xi'an Hongda Communications Technology Co., Ltd. by esteemed professors from Chang'an University—China’s premier institution for highway engineering and transportation machinery—HEM Group has maintained an uncompromising focus on independent R&D and design. Recognized as a certified "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology in 2006, our organization represents over two decades of mechanical mastery.
In 2017, to facilitate growing international operations and technical exchanges, HME TOP Machinery Equipment Co., Ltd. was established as the direct export arm. Today, we deliver complete operational chains covering highway construction, pavement rehabilitation, mining aggregates processing, and environmental dredging.
Our core engineering team holds extensive invention patents in mechanical dynamics, load-sensing hydraulic transmission, smart CAN-bus digital control systems, and optimal engine-power matching designed for heavy load cycles.
Combining automated heavy manufacturing with flexible custom engineering to support global OEM/ODM equipment needs.
Our production base features multi-axis robotic welding, high-precision laser profiling, and automated boring centers. Structural components for asphalt pavers and screeds undergo ultra-rigorous FEA stress analysis to guarantee performance under harsh dynamic loads.
By controlling everything from raw steel processing and hydraulic valve assembly to electronic control programming, we mitigate component bottlenecks, guaranteeing stable delivery schedules and cost-competitive global distribution.
Every paver, milling machine, and bitumen distributor undergoes rigorous operational trials before shipment, including thermal imaging of heating screeds, hydraulic pressure test cycles, and electronic sensor calibration.
Leading the shift toward digitalized paving, autonomous operations, and zero-emission drivetrains.
Our upcoming generation of SUM and DRF series asphalt pavers integrates 3D GNSS satellite positioning and non-contact ultrasonic grade sensors. By communicating directly with site BIM models, these systems automatically control screed height, slope, and steering, reducing mat thickness variance to within ±1.5 mm while eliminating traditional stringlines.
Uniform temperature distribution is vital for asphalt durability. HEM pavers employ electric heating screeds managed by pulse-width modulation (PWM) controllers, guaranteeing precise thermal consistency across working widths from 2.5 meters up to 12 meters. Dual-tamper high-compaction technology achieves pre-compaction density up to 95%, reducing the workload on subsequent road rollers.
With integrated IoT modules, fleet managers can monitor real-time fuel consumption, hydraulic fluid temperatures, engine diagnostic codes, and paving rates via a centralized dashboard. Remote firmware updates (OTA) and predictive fault alerts minimize costly field downtime for global engineering teams.
Targeting global carbon-neutral mandates, HME TOP Machinery is pioneering hybrid-electric drivetrains and low-emission burner systems for asphalt plants. Our Cold In-Place Recycling (CIPR) machinery allows 100% recycling of existing asphalt layers on-site, slashing material procurement costs and carbon footprints.
Providing specialized machinery tailored for complex, large-scale infrastructure operations.
Heavy-duty asphalt pavers, feeder machines, and synchronized chip sealers capable of continuous high-capacity placement on multi-lane highways and airport runways.
Compact cold milling machines, road wideners, micro-surfacing pavers, and road line markers designed for agile maneuvering in congested city environments.
Mobile jaw crushers, mobile primary vibrating screens, and heavy excavators designed to handle harsh rock extraction and urban construction waste recycling.
Comprehensive aftermarket infrastructure ensuring seamless operational uptime.
Exporting to more than 60 countries and regions worldwide—including India, Sri Lanka, Indonesia, Nigeria, South Africa, Russia, Uzbekistan, Ghana, Kenya, Fiji, and Bolivia—we understand that machine availability is the key factor in contractor profitability.
HME TOP Machinery maintains established regional technical support hubs and stocking centers to provide rapid-response servicing, technical guidance, and direct access to low-cost factory-certified spare parts.
