High-performance OEM engineering equipment designed for heavy-duty highway construction and municipal maintenance.
HEM Group was founded in 1998 by a distinguished group of professors from Chang'an University—Asia's premier institution for highway construction and automotive engineering—alongside top-tier road engineering experts.
Initially established as Xi'an Hongda Communications Technology Co., Ltd., HEM Group represents China’s earliest high-tech enterprise dedicated to independent R&D, mechanical dynamics design, and structural manufacturing of high-end pavement maintenance machinery.
Driven by university-level scientific research and engine-hydraulic matching patents, our machinery bridges the gap between academic innovation and heavy industrial performance. In 2006, HEM was officially designated a "High-Tech Enterprise" by the Shaanxi Provincial Department of Science and Technology. To further streamline global engineering partnerships and export operations, our dedicated international trading arm, HME TOP Machinery Equipment Co., Ltd., was founded in 2017.
The modern road construction landscape is undergoing a paradigm shift toward sustainability, precision hydraulics, high-density compaction, and digital telematics.
Sustainable pavement rehabilitation is replacing traditional full-depth replacement. CIPR technology mills the existing damaged road surface, mixes it with foamed bitumen or emulsion binding agents on-site, and lays down a rehabilitated structural base—reducing material haulage carbon emissions by up to 45% and cutting raw aggregate costs drastically.
Modern asphalt distributors and synchronized chip sealers utilize computer-controlled radar speed sensors and micro-metering pumps. This ensures a precisely calculated spray rate (kg/m²) regardless of vehicle speed fluctuations, eliminating bitumen bleeding, aggregate stripping, and weak bonding layers in asphalt overlays.
Slip-form concrete pavers have evolved from basic extrusion frames to 3D wire-free electronic levelling systems. Integrating laser receivers and total station guidance, our slip-form pavers achieve millimetric precision on highway barriers, curb gutters, and concrete pavements without setting traditional physical guide wires.
High-load commercial corridors require modified asphalt plants capable of dispersing SBS polymers and crumb rubber from recycled tires into bitumen. Modern continuous shear mills ensure high thermal stability, rutting resistance, and micro-cracking prevention across extreme ambient temperatures (-20°C to +70°C).
Global construction firms demand real-time diagnostics, fuel monitoring, engine load tracking, and wear-component life predictions. HME TOP machinery integrates CAN-bus control systems and satellite telematics for seamless integration into multi-brand contractor fleet management platforms.
By matching variable-displacement hydraulic pumps directly with engine torque curves, power losses during heavy milling or paving screed extension are minimized. Variable load-sensing hydraulics prevent fluid overheating, extending component operational lifespans by over 35%.
Operating from our 5,000 m² modern manufacturing hub, HEM Group combines digital precision manufacturing with integrated supply chain control to deliver unparalleled industrial machinery reliability.
Our smart facility incorporates CNC laser cutting, automated robotic welding cells, multi-axis gear milling, and computerized hydraulic pressure test benches. By maintaining 90%+ in-house control over structural fabrications and critical assemblies, we eliminate third-party component bottlenecks.
