Direct-from-factory solutions engineered for high productivity, thermal efficiency, and long lifecycle durability.
HEM Group was founded in 1998 by a distinguished group of professors from Chang'an University—China's leading institution for highway engineering, vehicle dynamics, and transportation infrastructure—alongside veteran senior experts in the heavy machinery industry. Initially established as Xi'an Hongda Communications Technology Co., Ltd., our enterprise stands as the earliest high-tech pioneer dedicated to independent research, thermal dynamics engineering, and mechanical structural design for road construction equipment in China.
Since our inception, we have consistently operated at the intersection of academic innovation and industrial manufacturing. Recognized as an official "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology in 2006, our continuous breakthroughs in mechanical dynamics, engine power matching algorithms, multi-stage hydraulic transmission, and digital electronic control systems have set regional benchmarks for reliability and efficiency.
To serve our expanding global clientele, HME TOP Machinery Equipment Co., Ltd. was established in 2017 as our dedicated international trade and technical support operation. This entity manages our end-to-end export sales, cross-border technical exchanges, on-site commissioning, and direct spare parts distribution across Asia, Africa, Europe, and the Americas.
Evaluating total cost of ownership (TCO), fuel efficiency, emissions standards, and continuous duty cycles for modern infrastructure developments.
Modern highway networks require high-precision paving and surface restoration equipment. Our synchronized chip sealers, asphalt spray pavers, and cold in-place recyclers allow municipal contractors to extend pavement life cycles while reducing material consumption by up to 35% compared to traditional overlay methods.
Rapid urban renewal demands compact, high-yield aggregate crushing and screening systems. Our mobile jaw crushers and mobile vibrating screens offer quick on-site setup, eliminating raw material transport costs and yielding refined aggregate graded for immediate concrete production.
Navigable inland waterways, reservoirs, and coastal estuaries require specialized aquatic machinery. Our amphibious excavators and Watcleaner aquatic restoration vessels perform eco-friendly vegetation clearing, riverbed silt dredging, and emergency flood-prevention channel widening.

How our Chang'an University heritage drives research in telemetry, thermal insulation, and hydraulic transmission systems.
Our heavy road maintenance machinery incorporates real-time CAN-bus electronic control systems developed in-house. Operators and fleet managers access continuous diagnostics—including hydraulic oil temperatures, engine torque load parameters, fuel efficiency metrics, and GPS spatial position—enabling predictive maintenance protocols that prevent unscheduled downtime.
Maintaining bitumen at optimal pumpable viscosities during long-distance transport is critical. Our semi-trailer asphalt tankers utilize multi-stage diesel burner heating units, high-density rock wool thermal insulation jackets, and internal heat exchange flues to limit temperature drop to under 2°C per 10 hours during transit.
By coupling aggregate delivery gates directly with computerized liquid asphalt spray nozzles on a single chassis, our synchronized chip sealers achieve perfect binder-to-aggregate adhesion before emulsion cooling occurs, ensuring maximum bond strength for high-speed road surfaces.
Responding to strict global emission regulations (Stage V / Tier 4 Final), our engine matching algorithms optimize fuel injection based on transient hydraulic load spikes. This reduces overall diesel consumption by 15-22% while providing peak breakout force when operating in high-resistance rock quarries or deep asphalt cuts.
Engineering specialized machinery tailored for earthmoving, road building, and mineral crushing operations.
We supply a comprehensive suite of earthmoving machinery including medium and compact wheel loaders, mini/versatile excavators, backhoe loaders, motor graders, and specialized modified machinery. Thousands of units operate daily in seaport developments, bridge footings, tunnel approaches, rural revitalization projects, agricultural land clearance, and residential estate infrastructure.
Every earthmoving unit is built with reinforced structural booms, heavy-duty bucket lips, and ergonomic cabs to ensure operator safety and peak digging forces in heavy clay or rocky terrain.
From primary asphalt mixing plants to high-precision asphalt pavers, road rollers, micro-surfacing machines, vacuum sweepers, and asphalt decanting systems, our equipment line covers every stage of road construction. Designed to handle modified polymer bitumen and recycled aggregates, our road machinery ensures long pavement fatigue life under high axle loads.
Our heavy-duty mining series features mobile jaw crushers, mobile primary screeners, and mobile cone crushers engineered for granite, basalt, limestone, and recycled concrete processing. These units deliver maximum reduction ratios, consistent product gradations, and low wear rates per ton of processed rock.

Direct expert responses addressing procurement specs, thermal efficiency, logistics, and operational compliance.
A: Chang'an University is widely recognized as China's top academic authority in road transport, mechanical dynamics, and highway engineering. Our founding team of professors translates advanced laboratory research—such as dynamic engine power matching, hydraulic fluid thermodynamics, and anti-segregation paver screed designs—directly into high-performance commercial machinery with field-proven reliability.
A: Our semi-trailer asphalt tankers feature multi-stage diesel heating burners, high-density rock wool thermal insulation layers (up to 100mm thick), and double-flue heat exchange systems. This heavy-duty thermal containment keeps temperature loss under 2°C per 10 hours, allowing liquid bitumen to be pumped directly into distributors or mixing plants upon arrival without additional reheating.
A: Yes. We offer customized engine configurations including Cummins, Perkins, Weichai, and Deutz diesel engines compliant with Euro Tier 3, Tier 4 Final, or Stage V emission regulations. Furthermore, electrical and hydraulic systems can be configured for extreme high-ambient desert environments or low-temperature Arctic operating zones.
A: We provide full end-to-end technical support including export documentation, marine insurance, and customs assistance. Post-delivery, our international engineering teams provide on-site machine setup, hydraulic system calibration, and operator safety training. Spare parts are dispatched via priority air freight from our local warehouse hubs in Russia, Malaysia, South Africa, Kenya, and Uzbekistan.
A: Traditional road surface maintenance involves spraying bitumen binder and spreading aggregate chips in separate sequential passes. Our synchronized chip sealers spray binder and distribute stone aggregate simultaneously within fractions of a second. This guarantees optimal aggregate embedment before binder cooling occurs, reducing surface stripping, cutting labor requirements by 50%, and extending highway service life.
