Explore our industrial-grade pavement equipment lineup designed for precision aggregate delivery, bitumen distribution, and road rehabilitation.
In modern highway rehabilitation, chip sealing, surface dressing, and base course stabilization, aggregate distribution uniformity dictates long-term pavement durability.
As a leading OEM Aggregate Spreading Truck Manufacturer & Supplier, HEM Group delivers engineered aggregate spreading solutions that resolve traditional paving challenges—such as aggregate segregation, erratic material discharge rates, and uneven cross-sectional spreading dynamics. Integrating dynamic hydraulic feedback loops with automated volumetric measurement mechanisms, our equipment guarantees precision application across diverse aggregate fraction sizes (ranging from 3mm aggregate chips to 30mm base stones).
Whether deployed in synchronized chip sealing operations alongside asphalt distributors or used as standalone high-speed aggregate spreaders on macro-scale infrastructure projects, OEM Aggregate Spreading Trucks engineered by HEM Group offer unparalleled mechanical reliability, low operational maintenance overhead, and multi-chassis structural adaptability.
HEM Group (originally established in 1998 as Xi'an Hongda Communications Technology Co., Ltd.) was founded by senior engineering professors from Chang'an University—China's premier institution renowned globally for highway engineering, heavy machinery dynamics, and vehicle design research. This deep-rooted academic background infuses continuous scientific innovation into our OEM equipment production line.
Our research teams pioneered advanced power-matching control loops for high-load hydraulic systems, eliminating hydraulic pressure spikes and ensuring seamless power output across variable spreading speeds.
Integrating micro-processor closed-loop control systems, our aggregate trucks automatically recalibrate feed gates in real-time according to radar-measured chassis speed, preserving uniform target application rates.
Recognized as a Shaanxi Provincial High-Tech Enterprise since 2006, HEM Group holds dozens of engineering patents in engine matching, anti-segregation hopper design, and modular spreader assembly.
Every aggregate spreading vehicle manufactured in our 50,000 m² state-of-the-art facility undergoes rigorous stress analysis and functional testing. We provide customized OEM solutions tailored to chassis requirements from leading international heavy truck brands (e.g., Sinotruk HOWO, Shacman, Volvo, MAN, Mercedes-Benz, and Scania).

Traditional aggregate dump trucks suffer from gravity segregation, where coarse stones collect at hopper edges while fines aggregate in the center. HEM Group's aggregate spreading trucks feature internal v-shaped dynamic baffles and continuous hydraulic spiral augers that maintain homogeneous material blend up to the exact moment of discharge onto the road surface.
Equipped with pneumatically controlled multi-segment discharge gates, operators can instantly adjust spreading width in increments as fine as 250mm. This prevents aggregate waste during shoulder paving, lane repairs, or irregular urban intersection maintenance.
Sourcing OEM Aggregate Spreading Trucks directly from Chinese specialized manufacturers offers significant competitive advantages for international EPC contractors, equipment leasing firms, and municipal public works departments.
Leveraging China's comprehensive industrial supply chain for raw steel, high-pressure hydraulics, and vehicle electronics, HEM Group manufactures world-class equipment at a fraction of Western OEM procurement costs, delivering rapid ROI for fleet operators.
We work directly with foreign clients to modify hopper dimensions, hydraulic plumbing, electrical voltages, and branding colorways. We support Complete Knocked Down (CKD) or Semi-Knocked Down (SKD) shipping to optimize import tariffs.
Every unit undergoes strict quality assurance protocols—including 100-hour continuous hydraulic circuit testing, ultrasonic weld inspection, and automated calibration trials—ensuring complete reliability upon site delivery.
Infrastructure projects span drastically different climates and terrain conditions. HEM Group's OEM Aggregate Spreading Trucks are engineered to maintain operational integrity under extreme conditions around the globe.
Operating in mountainous regions requires engines calibrated for thin air and steep gradients. Our power-matched auxiliary engines and heavy-duty braking systems ensure consistent aggregate feed even on 12% highway inclines in high-altitude environments such as Central Asia and South America.
In humid tropical climates (Southeast Asia, Coastal Africa), aggregate dampness often leads to gate clogging. Our specialized anti-bridging agitator shafts prevent damp chips from clumping, ensuring seamless distribution during chip-seal surfacing.
Equipped with heavy-duty oil cooling radiators and dust-proof electrical cabinets (IP65 rated), our spreading trucks perform continuously in ambient desert temperatures exceeding 50°C without hydraulic fluid breakdown or control system overheating.
Using our precision gate control, municipal road teams can execute narrow trench backfilling and shoulder widening with zero material spillover into adjacent traffic lanes, cutting post-construction cleanup labor by over 70%.
At HEM Group, selling machinery is only the beginning of our partnership. Through our specialized export entity, HME TOP Machinery Equipment Co., Ltd. (est. 2017), we provide end-to-end support for international infrastructure clients.
Our OEM vehicles can be configured to comply with CE safety directives, ISO 9001 quality management benchmarks, and Euro III through Euro VI / Tier 4 Final engine emission mandates based on local destination market laws.
We maintain active distribution partnerships, service teams, and regional spare parts hubs across Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, and Sri Lanka to respond rapidly to field service requests.
We guarantee low-cost spare parts supply for all OEM models for over 15 years, backed by expedited global air logistics to minimize site downtime in the event of unexpected component wear.
The road construction industry is undergoing a digital transformation driven by environmental regulations, labor shortages, and demand for longer pavement lifespans. As an industry pioneer, HEM Group incorporates next-generation technologies into our OEM production lines.
Modern aggregate spreaders are becoming fully connected IoT nodes. Fleet managers can monitor real-time material consumption, total square meters covered, GPS location, fuel burn rates, and maintenance alerts via a centralized dashboard, maximizing site efficiency.
Future iterations of our aggregate trucks integrate forward-looking lidar sensors that evaluate surface macro-texture prior to spreading, automatically adjusting volumetric discharge rates in real-time to match road surface roughness variations.
HEM Group was founded in 1998 by professors from Chang'an University and road construction experts (originally named Xi'an Hongda Communications Technology Co., Ltd.). It stands as the earliest high-tech enterprise focusing on independent R&D of road machinery in China. In 2017, HME TOP Machinery Equipment Co., Ltd. was established to handle global exports, technical support, and international trade.
Our complete machinery chain includes road milling machines, asphalt distributors, pavers, chip sealers, slurry seal machines, road wideners, mobile crushers, backhoe loaders, wheel loaders, and excavators.
Our products are exported to more than 60 countries, including India, Sri Lanka, Indonesia, Nigeria, South Africa, Eritrea, Mozambique, Congo, Australia, Fiji, and Bolivia.
Our micro-processor controlled aggregate spreading trucks maintain volumetric metering accuracy within ±1%. Closed-loop tachometer feedback automatically adjusts gate aperture size dynamically relative to vehicle road speed changes.
Yes. As a specialist OEM manufacturer, we design upper-structure spreading modules compatible with all major international chassis brands, including Sinotruk, Shacman, MAN, Volvo, Mercedes-Benz, Scania, and Isuzu, ensuring seamless mechanical and hydraulic coupling.
Our standard roller discharge mechanisms handle aggregate stone fractions from 3 mm fine chips up to 30 mm gravel. Gate clearance gap dimensions can be calibrated rapidly from the cab touch display.
