High-precision paving, slipform kerb casting, and intelligent road construction solutions directly from our Industry 4.0 factory.
Founded by Chang'an University Highway Machinery Experts | Pioneering Highway Engineering Innovations Since 1998
HEM Group (HME TOP Machinery Equipment Co., Ltd.) was established in 1998, originating from the elite academic research teams of Chang'an University—China's premier institution for highway construction and mechanical engineering research. Initially registered as Xi'an Hongda Communications Technology Co., Ltd., our enterprise stands as one of the earliest high-tech pioneers devoted to the independent R&D and custom fabrication of heavy-duty road construction machinery.
Over two decades of rigorous field testing, mechanical dynamics simulation, and hydraulic system optimization have propelled HEM Group into an international authority. Recognized as a official "High-Tech Enterprise" by the Shaanxi Provincial Department of Science and Technology in 2006, our engineering roster holds extensive invention patents covering key fields: advanced engine power matching algorithms, high-frequency vibratory extrusion systems, closed-loop hydraulic transmissions, and digital microprocessor auto-leveling networks. To scale global procurement access, HME TOP Machinery Equipment Co., Ltd. was created in 2017 to handle direct factory exports, OEM customization schemes, and global field engineering support.
Traditional precast kerb placement suffers from joint degradation, intensive manual labor costs, and poor structural alignment over extended highway spans. Premium curb pavers utilize continuous slipform extrusions—feeding zero-slump concrete or dense asphalt matrix into custom-milled molds under intense hydraulic compaction. The result is a monolithic kerb or gutter structure with superior flexural strength, impermeability, and sub-millimeter level precision guided by 3D stringless GNSS sensors.

Equipped with dual-slope electronic sensors and auto-leveling algorithms. System continuously adjusts elevation and cross-slope within ±1mm accuracy even across uneven subgrades.
Constructed from wear-resistant HARDOX® steel alloys. Quick-change mold mounts allow transition between barrier walls, curb-and-gutter, and drainage ditches in under 45 minutes.
Load-sensing hydraulic pumps deliver precise dynamic flow to vibrators and crawlers, reducing overall fuel consumption by up to 22% compared to conventional constant-flow pavers.
Tailored engineering packages designed for global contractors, municipal authorities, and mega highway developments.
Extruding heavy tall-wall concrete barriers (up to 1.2m height) directly on highway median corridors. Our slipform pavers deliver high structural integrity capable of withstanding heavy impact testing while eliminating temporary formwork setup cost.
High-efficiency curb slipforming along urban arterials and residential developments. Integrates integrated gutter pan slipforming with automated radius steering down to 2.5-meter tight turning circles.
Precision slipforming for massive trapezoidal drainage ditches and heavy airfield apron boundaries. Designed to process extra-dense, low-slump concrete mixes with zero structural slumping during initial setting.








Advanced Robotics, Unmatched OEM Customization, and High-Volume Production Integrity.
Spanning over 50,000 square meters of state-of-the-art heavy manufacturing space, HEM Group operates dedicated automated robotic welding cells, high-capacity CNC plasma and laser cutters, ultrasonic weld flaw detectors, and full-climate paint lines. Our vertical integration guarantees that over 85% of critical chassis components and structural weldments are fabricated in-house under strict ISO 9001 and CE compliance protocols.






Whether projects demand unique curb cross-sections, specialized crawler track pads, tropicalized cooling radiators, or custom diesel power ratings, our engineering team provides full 3D CAD modeling and tailored fabrication.
By leveraging China's dense industrial manufacturing ecosystem and maintaining raw material strategic buffers, we protect global clients from global supply chain shocks while offering competitive Total Cost of Ownership (TCO).
Next-generation automation, stringless 3D guidance systems, hybrid powertrains, and AI slump diagnostics.
Replacing traditional stringlines with high-precision RTK-GNSS and robotic total station tracking. Eliminates stringline setup labor, accelerates project turnaround by up to 40%, and guarantees millimeter-level accuracy over irregular terrains.
Integrating real-time acoustic sensors inside the mold chamber. Machine AI automatically detects concrete workability variations and dynamically adjusts hydraulic vibrator frequency to eliminate honeycombing without operator intervention.
Transitioning heavy slipform pavers to high-voltage electric motor drives powered by modular lithium battery packs or hydrogen fuel cells for zero-emission urban construction compliance.
Streamlined international logistics, transparent lifecycle pricing, and rapid payback schedules for contractors.
When selecting a reliable curb paver factory, enterprise procurement managers must evaluate more than just initial FOB prices. Operational expenditure—including fuel consumption, replacement vibrator costs, mold wear rates, and field downtime—dictates true project profitability.
All critical hydraulic systems utilize globally standardized components (e.g., Rexroth pumps, Danfoss proportional valves, Parker hose fittings), ensuring fast local parts availability across any continent.
Our machine frames are engineered with fold-down hoppers and quick-detach crawler assemblies, allowing even large slipform pavers to fit into standard 40ft High Cube containers to cut international ocean freight costs.
By replacing manual slipform crews of 15+ workers with a 3-person automated paver team, contractors achieve continuous daily placements of over 1,500 linear meters, delivering capital payback within 4 to 6 months.
Extensive export operations serving over 60 countries with on-site technician training and regional spare parts hubs.
Our heavy machinery is currently deployed on major infrastructure projects across Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, Sri Lanka, India, Nigeria, Mozambique, Australia, Fiji, Bolivia, and beyond. We understand that field uptime is paramount.






Dedicated multilingual service engineers ready for deployment within 48 hours to execute commissioning, hydraulic calibrating, and operator safety training directly at your job site.
Regional distribution hubs stock consumable items, sensor cables, hydraulic seals, and wear plates, guaranteeing fast dispatch to minimize jobsite downtime.
Expert answers regarding curb paver procurement, operation, concrete mix design, and factory OEM support.
Slipform pavers require a low-slump concrete mix, typically between 10mm and 30mm (0.5 to 1.2 inches). The aggregate ratio must be carefully balanced with adequate fine material to ensure the extruding kerb maintains structural shape without slumping or cracking before initial set.
Yes. Our machines utilize modular quick-change mounting mechanisms. By simply unbolting the existing mold and attaching a new HARDOX® steel mold (such as converting from a standard barrier wall to a curb-and-gutter or flat ribbon curb), contractors can transition between profiles in under an hour.
Traditional stringlines use physical stakes and wires to set elevation/steering sensors. 3D stringless systems connect directly to Leica, Topcon, or Trimble total stations/GNSS networks, allowing the curb paver to read digital CAD terrain models automatically. This eliminates manual wire setup errors and drastically cuts site prep labor.
We provide extensive OEM modifications including specific diesel engine emissions compliance (Tier 3 to Stage V), custom hydraulic vibrator ports, specialized track pads, custom mold geometry design, client brand paint matching, and integrated high-pressure washer systems.
