High-performance machinery designed for bridge deck paving, asphalt recycling, precise bitumen distribution, and earthmoving applications.
Tracing our technical lineage from top-tier research universities to global heavy equipment manufacturing leadership.
Founded in 1998 as Xi'an Hongda Communications Technology Co., Ltd. by an elite group of professors from Chang'an University—China's premier institution for highway and bridge engineering—HEM Group represents a synthesis of academic science and industrial application. Our foundation rests upon rigorous research in mechanical dynamics, hydraulic matching, and electronic automation.
Recognized officially as a High-Tech Enterprise by the Shaanxi Provincial Department of Science and Technology in 2006, our engineering teams have pioneered breakthrough inventions in hydraulic transmission circuits, low-emission engine matching, real-time material feeding telemetry, and digital slipform levelling systems tailored for complex viaduct structures.
In 2017, HEM Group established HME TOP Machinery Equipment Co., Ltd. as its dedicated international engineering and export arm. HME TOP handles global technical exchange, custom OEM design engineering, international logistics, and comprehensive remote/on-site after-sales technical support across more than 60 countries worldwide.
Why leading global engineering contractors and equipment dealers partner with specialized OEM factories in China for bridge and road construction machinery.
China's heavy industrial ecosystem provides unmatched access to high-strength structural steel alloys (such as Q355B and Q690D), precision hydraulic valve blocks, world-class powertrain components, and specialized electronic control hardware within a compact geographic radius. This minimizes lead times and optimizes build consistency.
Unlike rigid off-the-shelf Western manufacturers, Chinese OEM leaders like HEM Group offer highly flexible engineering customization. From modifying slipform paving widths for non-standard bridge decks to configuring multi-voltage digital control systems for regional grid compatibility, OEM customization is built into our core operations.
By leveraging advanced automated robotic welding, lean assembly line modularity, and direct factory pricing, Chinese OEM machinery drastically reduces capital expenditure (CAPEX) while ensuring long-term spare parts affordability (OPEX) at costs up to 35-50% lower than European equivalents.
How modern IoT automation, precision leveling, and eco-friendly powertrains are redefining bridge deck erection and highway rehabilitation.
| Technology Vector | Traditional Approach | Modern OEM Innovation (HEM Group Standard) | Impact on Bridge Construction |
|---|---|---|---|
| Pavement Leveling & Steering | Manual stringlines & operator steering | 3D Laser & GPS/GNSS automated slipform control | Millimeter-accurate deck smoothness & zero structural tilt errors. |
| Bitumen Spraying Precision | Fixed-rate pumps with manual speed sync | Intelligent computer-matched flow valves & CAN-bus speed tracking | Uniform binder application, eliminating deck delamination risks. |
| Powertrain Efficiency | High-emission diesel engines without load sensing | EU Stage V / US Tier 4 Final engines with eco-hydraulic power matching | 20-30% fuel savings, lower carbon footprint, and reduced noise levels. |
| Telematics & Fleet IoT | Break-fix maintenance & manual logs | Real-time cloud diagnostics, remote fault code reading & predictive maintenance | Unplanned jobsite downtime reduced by over 45%. |
Demonstrating versatile performance across challenging global job sites, urban elevated structures, and mega bridge projects.
Bridge deck paving requires precise weight distribution and crack-free asphalt laying. Equipment such as our Multi-functional Slip-Form Pavers and Asphalt Paver Feeders guarantee continuous material transfer without mechanical impact on structural bridge joints, maintaining structural integrity.
From sub-zero Siberian highway extensions to humid coastal viaduct projects in Southeast Asia and high-altitude Andean bridges, HEM machinery is engineered with thermal-regulated hydraulic oil coolers, heavy-duty anti-corrosion marine primers, and dust-sealed electronics.
Modifying active elevated bridges and highway ramps without closing traffic channels demands compact machinery. Our DK1800 Road Widener and compact Mini Excavators allow precise shoulder paving, trenching, and utility installation within single-lane operational envelope limits.





Tailored equipment packages and lifecycle procurement management for international contractors, government transport ministries, and equipment rental fleets.
We provide full-spectrum engineering customization services. From tailored chassis dimensions to custom hydraulic flow rates and white-label branding for international distributors, our engineering office turns project-specific requirements into certified operational machinery.
Minimizing equipment downtime is our paramount commitment. HME TOP maintains dedicated spare parts hubs and fast-dispatch logistics pathways across Southeast Asia, Africa, Eastern Europe, and Latin America to deliver critical components rapidly.






Addressing technical, operational, and procurement queries for global bridge construction contractors and OEM partners.
Our quality control system stems from over 25 years of engineering experience rooted in Chang'an University's research traditions. Every machine undergoes rigorous structural FEA stress simulation, hydraulic bench pressure testing, dynamic track running tests, and full factory acceptance testing (FAT) before shipment. Components are sourced from certified tier-1 global suppliers (e.g., Rexroth hydraulics, Cummins engines, Schneider electricals).
We provide extensive custom engineering options, including adjustable paving widths (from 2.5m to over 12m), custom screed heating configurations (electric or burner-based), specialized crawler track pad compounds for bridge deck preservation, dual-line automated leveling sensor mounts (laser/ultrasonic/3D Leica interface), and specialized engine emission setups tailored to regional fuel regulations.
Bridge deck waterproofing requires absolute spraying uniformity to prevent moisture ingress and concrete rebar corrosion. Our intelligent bitumen distributors feature computer-controlled spray bars with individual nozzle control, heat-jacketed circulation pumps, and automatic speed-matching telemetry to guarantee exact application rates (in kg/m²) regardless of truck driving speed variations.
Standard machinery models are usually available within 15 to 30 days. Specialized custom OEM configurations require 35 to 60 days depending on structural engineering requirements. Through HME TOP Machinery Equipment Co., Ltd., we handle complete export documentation, Ro-Ro / Flat Rack container packing, customs clearance, and global port logistics seamlessly.
We provide a 12-month or 2,000-hour operational warranty across all primary machine lines. Our global technical response team offers 24/7 online video diagnostics, emergency spare parts air-freight dispatch, and on-site engineering commissioning teams located across regional distribution hubs in Southeast Asia, Africa, Eastern Europe, and South America.
