Explore our premium lineup of engineered road building machinery, asphalt processing plants, and heavy-duty earthmoving solutions built for worldwide operations.
HEM Group was established in 1998 (originally registered as Xi'an Hongda Communications Technology Co., Ltd.) by a distinguished collective of engineering professors from Chang'an University—China's premier institution for highway engineering research—and veteran road construction machinery experts. We stand as the pioneer high-tech enterprise dedicated to independent R&D, mechanical dynamics, and specialized pavement maintenance design in China.
Driven by advanced technology integration, HEM Group focuses on solving complex road engineering challenges. Our intellectual portfolio encompasses dozens of national invention patents covering engine power matching, high-torque hydraulic transmission systems, dynamic load distribution, and digital microprocessor electronic controls.
In 2006, the Shaanxi Provincial Department of Science and Technology officially certified HEM Group as a "High-Tech Enterprise." To streamline international commerce, export logistics, and worldwide customer support, our dedicated international sales arm—HME TOP Machinery Equipment Co., Ltd.—was established in 2017 to deliver customized OEM solutions directly to global contractors.
Analyzing the shift from conventional tow-behind aggregate hoppers to computer-controlled self-propelled and synchronized chip sealers in modern pavement preservation.
Modern highway authorities demand sub-percentage accuracy in aggregate application rates. Intelligent chip spreaders utilize real-time radar velocity sensing coupled with automated gate openings to maintain consistent distribution (kg/m²) regardless of vehicle speed fluctuations.
The industry is rapidly transitioning toward Synchronized Chip Sealers—combining high-pressure bitumen emulsion spraying and aggregate spreading on a single chassis within a fraction of a second. This eliminates emulsion cooling and prevents vehicle tires from damaging the binder layer.
Preventative maintenance techniques like chip sealing reduce lifecycle road repair costs by up to 70% compared to traditional hot-mix asphalt overlays. High-efficiency spreaders minimize aggregate waste and lower overall carbon emissions on major infrastructure projects.
How HME TOP Machinery resolves critical technical and operational challenges faced by international road contractors and government ministries.
Conventional spreaders suffer from aggregate bridging and uneven distribution across wider working spans, leading to surface streaks, premature aggregate loss (fly-rock), and costly re-work.
Our self-propelled aggregate chip spreaders utilize dual spiral feeder shafts with anti-segregation baffles and individually controlled pneumatic gates. This ensures uniform aggregate flow across adjustable working widths (up to 4.5 meters).
Operating under high ambient temperatures in regions like Africa, the Middle East, or Southeast Asia often causes hydraulic fluid overheating and power loss in heavy road machinery.
Engineered with proprietary hydraulic oil cooling loops and adaptive power-matching technology derived from Chang'an University research, our spreaders operate continuously in ambient conditions up to 55°C without efficiency drop.
