Direct factory solutions engineered with accurate measuring systems, high torque powertrains, and rugged structural integrity.
Founded in 1998 by a distinguished cadre of professors from Chang'an University—China's premier academic institute for highway engineering and heavy machinery design—HEM Group (originally Xi'an Hongda Communications Technology Co., Ltd.) established the benchmark for domestic road machinery R&D. Over two decades of relentless technological refinement transformed a university research engine into a global heavy equipment enterprise.
Recognized as an official "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology in 2006, our engineering teams hold milestone patents in mechanical dynamics, engine power matching, hydraulic closed-loop transmission systems, and CAN-bus digital electronic control architectures. In 2017, to serve expanding international market demands, HME TOP Machinery Equipment Co., Ltd. was formed to direct global sales, export logistics, custom OEM manufacturing, and round-the-clock technical dispatch.
Strategic insights into shifting OEM requirements, green infrastructure mandates, and intelligent automation in global civil engineering.
Modern EPC contractors and municipal authorities require millimetric accuracy. Equipment integrated with smart micro-controllers, load-sensing hydraulic proportioning, and GPS/GNSS automated levelling reduces material waste by up to 18% while guaranteeing strict compaction and spreading density compliance.
Decarbonization mandates have accelerated demand for asphalt recycling and warm-mix equipment. Machinery capable of milling, pulverizing, and re-stabilizing deteriorated pavements in-situ drastically cuts bitumen consumption, transportation energy, and lifecycle maintenance expenditure.
Global procurement directors prioritize suppliers offering customizable chassis, modular power packs, and regional emission compliance (Stage V, Tier 4 Final, Euro VI). OEM adaptability reduces fleet downtime and aligns heavy equipment with unique geographical terrains.
From initial earthworks and aggregate crushing to continuous highway paving and micro-surfacing maintenance.
HEM Group’s flagship road engineering series represents decades of scientific refinement in thermal management, hydraulic synchronization, and binder metering. Key machines in this ecosystem include:
Equipped with high-frequency vibratory screeds, automatic gas/electric heating systems, and dual-layer auger feeding controls. The SUM7280DS integrated spray paver applies emulsion binder and places hot mix asphalt simultaneously, ensuring superior layer bonding and zero tack-coat tire pickup.
Featuring computer-controlled computerized spray bars with dynamic linear speed compensation. The DGL5250TFS cement spreader guarantees precise dosage rates (kg/m²) regardless of vehicle speed, preventing subgrade stabilization failure.
Combines aggregate distribution and emulsion spraying into a single synchronous mechanism, forming high-friction seal coats that eliminate moisture infiltration on highways and airport runways.
Heavy-duty milling drums with toolholder quick-change systems designed to strip asphalt pavement cleanly while maintaining strict depth gradients. Recyclers re-introduce asphalt reclaimed material directly into sub-base layers.
Engineered for high load capacity, low operational cost per ton, and rugged structural endurance across heavy civil infrastructure and hard-rock quarrying operations.
Zero-tail-swing excavators powered by low-emission engines. Advanced load-sensing hydraulics allow multi-function fluidity for urban trenching and site preparation.
Track-mounted primary jaw crushers and vibrating screens capable of processing up to 500 TPH of hard basalt, granite, or demolition rubble directly at quarry faces.
All-terrain "Iron Spider-Man" walking excavators with multi-articulated hydraulic legs designed for extreme mountain slopes, landslide clearance, and marshland engineering.
Continuous investment in robotic welding, high-precision machining centers, and comprehensive quality validation protocols.
Providing custom OEM machinery and reliable component supply across 60+ countries throughout Europe, Asia, Africa, and the Americas.
HEM Group specializes in contract manufacturing and OEM customization. Whether adapting hydraulic systems for high-altitude mining in South America or re-engineering thermal bitumen burners for arctic sub-zero road construction in Northern Eurasia, our R&D team provides comprehensive design-to-delivery support.
