Direct factory supply featuring heavy-duty engineering, micro-surfacing precision, and high-efficiency pavement maintenance systems.
Founded in 1998 by a distinguished group of professors from Chang'an University alongside premier highway engineering experts, HEM Group (originally established as Xi'an Hongda Communications Technology Co., Ltd.) represents the vanguard of independent research, digital dynamics, and heavy equipment manufacturing in China.
Guided by high-tech research and international quality standards, our engineering team holds numerous patents across mechanical dynamics, engine power matching, high-pressure hydraulic transmission, and digital electronic control systems. In 2006, our technical breakthroughs were officially recognized with the "High-Tech Enterprise" designation by the Shaanxi Provincial Department of Science and Technology.
To streamline international logistics, customs compliance, and client-centric global support, we launched our dedicated export arm, HME TOP Machinery Equipment Co., Ltd. in 2017. Today, we deliver end-to-end, one-stop solutions spanning sealcoating squeegee units, slurry seal machines, asphalt plants, mining crushers, and heavy earthmoving machinery worldwide.
Transitioning from reactive road repairs to proactive, micro-engineered surface sealing solutions.
While spray systems apply a surface layer, mechanical sealcoat squeegee machines physically force high-viscosity asphalt emulsions, rubberized sealers, and aggregate mixtures deep into micro-fissures and porous void spaces. This mechanical packing restores structural binding strength, prevents water intrusion, and extends pavement lifespan by up to 300% compared to basic spray coats.
Modern sustainability mandates favor scrap rubber and SBS polymer-modified asphalt emulsions. These highly viscous binders demand heavy-duty squeegee drag boxes with adjustable blade durometers and intelligent fluid circulation systems to prevent material shearing, segregation, and premature cooling during continuous paving operations.
Global municipal tenders increasingly mandate real-time application metering to reduce volatile organic compound (VOC) emissions and eliminate material waste. Integrated digital controls ensure exact gallon-per-square-yard distribution regardless of ground speed, guaranteeing compliance with stringent local DOT regulations.
From municipal street maintenance to high-altitude emergency earthmoving and specialized aggregate processing.
We manufacture a full line of specialized pavement preservation equipment including sealcoat squeegee machines, asphalt mixing plants, intelligent bitumen distributors, micro-surfacing pavers, synchronized chip sealers, and road milling units. Deployed worldwide across municipal networks, highway shoulders, and airport runway preservation projects.
Supplying high-durability wheel loaders, mini and heavy excavators, backhoe loaders, motor graders, and specialty "Iron Spider-Man" walking excavators engineered for extreme slopes, mountain road restoration, riverbed dredging, municipal revitalization, and rapid emergency rescue operations.
Complete crushing and screening plant solutions including mobile primary jaw crushers, mobile cone/roller crushers, and heavy-duty vibrating screens designed to turn raw quarry rock and recycled road asphalt into tightly graded aggregate base material for instant construction reuse.
Combining academic research expertise with rigorous operational reliability and custom engineering flexibility.
Direct academic heritage from Chang'an University focusing on hydraulic dynamics, digital controls, and engine power matching.
Tailored equipment designs customized to fit specific binder formulations, climate conditions, and local chassis dimensions.
Proven track record with machinery operating in over 60 countries across Africa, Central Asia, Southeast Asia, South America, and Europe.
Round-the-clock online engineering assistance, rapid OEM spare parts fulfillment, and on-site field training for operator teams.
Pioneering smart automation, IoT telematics, and eco-friendly paving solutions for zero-emission infrastructure projects.
Integrating ultrasonic surface profiling sensors and auto-adjusting hydraulic downforce actuators to automatically compensate for rutting, wheel depressions, and uneven pavement cross-slopes in real-time.
Developing zero-emission hydrostatic drive systems that reduce fuel burn during idle sealcoating runs by up to 40%, meeting strict Tier 4 Final and Stage V urban noise and carbon emission mandates.
Cloud-connected diagnostic suites that track emulsion temperature, mixing shear rates, flow velocity, and square-yard coverage metrics, broadcasting live jobsite performance data to project engineers.
Our equipment is deployed across key international infrastructure projects in India, Sri Lanka, Indonesia, Malaysia, Uzbekistan, Russia, Nigeria, South Africa, Eritrea, Mozambique, Congo, Ghana, Kenya, Australia, Fiji, Bolivia, and beyond.












Addressing key technical, procurement, and operational inquiries from global pavement maintenance contractors.
A sealcoat squeegee machine mechanically presses high-viscosity asphalt emulsion and sand/aggregate slurries down into asphalt cracks and micro-fissures, creating a dense mechanical bond. Spray systems simply lay material on top, which can wear away faster under heavy traffic loads.
Yes. Our engineering team designs custom heat-jacketed fluid lines, heavy-duty agitator tanks, and variable-durometer squeegee blades engineered specifically to process polymer-modified bitumen, crumb rubber sealers, and high-solid slurry seal mixes without clogging or material degradation.
Standard machine configurations generally ship within 15–25 business days. Custom OEM orders featuring specific engine specifications (Euro V / Tier 4), custom tank capacities, or specialized hydraulic attachments require approximately 30–40 days from final technical sign-off.
We support global operators through dedicated service teams and localized partner networks in regions like Russia, South Africa, Malaysia, and Uzbekistan. Standard replacement items (wear blades, hydraulic seals, spray nozzles) are stocked for immediate express air shipping at competitive factory rates.
