Direct OEM Factory Solutions for International Hire Suppliers and Infrastructure Contractors
Transitioning from Capital Expenditure (CAPEX) to Operational Efficiency in Modern Infrastructure Rehabilitation
Highway authorities and civil engineering contractors worldwide are increasingly shifting from direct machine ownership to flexible short- and long-term sprayer hire models. Emulsion sprayers—essential for tack coating, chip sealing, micro-surfacing, and prime coating—require high calibration accuracy and minimal downtime. Sourcing through specialized hire fleets backed by robust OEM manufacturing guarantees operational continuity and compliance with strict environmental standards.
Equipment rental suppliers demand machines designed for durability, rapid maintenance turnaround, and multi-region regulatory compliance. Modern OEM factories must deliver modular bitumen emulsion sprayers equipped with automated cleaning systems, intelligent spray bar width controls, and multi-viscosity heating jackets compatible with Rapid Setting (RS), Medium Setting (MS), and Polymer-Modified Emulsions (PME).
Cold-application bitumen emulsions reduce carbon emissions by up to 40% compared to traditional hot-mix asphalt tack applications. Consequently, public tenders in Europe, North America, and Asia-Pacific mandate computerized dosage accuracy within ±1.5%, forcing rental companies to upgrade their fleets with next-generation smart emulsion sprayers from proven OEM partners.
Integrating Hydraulic Precision, Thermodynamic Control, and Autonomous Telematics
Rooted in academic collaboration with Chang'an University—China's premier institution for highway engineering technology—our OEM bitumen emulsion sprayers incorporate advanced fluid dynamics and thermodynamic principles designed to prevent emulsion breaking inside pumps and spray bars.

How HEM Group & HME TOP Machinery Deliver Cost-Effective, World-Class Equipment to Global Rental Fleet Operators
Operating a modernized 5,000 m² centralized production base equipped with robotic laser cutting, automated welding stations, and high-precision hydrostatic test benches, our facilities achieve an annual output exceeding 5,000 units across earthmoving, crushing, and road maintenance series.
Founded in 1998 by Chang'an University professors and highway machinery engineers (originally Xi'an Hongda Communications Technology Co., Ltd.), our engineering team holds numerous patents in mechanical dynamics, engine power matching, hydraulic transmission, and digital electronic control.
Equipment is pre-engineered for rapid flat-rack or containerized shipping. Spare parts standardization ensures rental hire suppliers in Europe, South America, Africa, and Southeast Asia can source components locally or receive OEM air-freight replacements within 48 hours.
Pioneering High-Tech Highway Construction & Maintenance Solutions Since 1998
HEM Group was founded by a group of professors from Chang'an University and experts in the road building industry in 1998, initially named Xi'an Hongda Communications Technology Co., Ltd. It stands as the earliest high-tech company focusing on independent research and design of road construction equipment in China.
In 2006, the company was officially recognized as a "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology. To strengthen international trade and technical exchange, we established HME TOP Machinery Equipment Co., Ltd. in 2017, dedicated to managing export sales, global technical support, and international after-sales services.
Today, our product range forms a complete ecosystem including road milling machines, asphalt distributors, pavers, chip sealers, slurry seal pavers, road wideners, excavators, bulldozers, and mobile aggregate crushers exported to over 60 countries.
Deploying OEM Emulsion Sprayers Across Extreme Climates & Diverse Engineering Applications
Designed for high-speed continuous spraying prior to asphalt overlay placement. Computerized radar controls precisely meters emulsion at rates down to 0.25 kg/m², avoiding runoff, bleeding, or uneven adhesion on freshly milled pavement surfaces.
Compact chassis options equipped with flexible hand-held spray wands and narrow telescopic spray bars allow hire fleets to service tight municipal roadways, parking facilities, and urban residential street maintenance without obstructing traffic lanes.
Engineered to operate reliably under extreme conditions—from high ambient temperatures (+50°C in Middle Eastern desert sites) with heavy dust filters, to sub-zero alpine conditions (-25°C in Northern Europe) utilizing dual-burner fast heating circuits.
Providing heavy equipment synergy across seaport, bridge, and industrial zone construction projects globally.
Complete paving chains including asphalt distributors, pavers, chip sealers, and micro-surfacing machinery.
Mobile primary jaw crushers and screening units serving heavy aggregate processing operations.
Optimizing Total Cost of Ownership (TCO) for International Equipment Rental Providers
Modern equipment rental companies rely on real-time data to protect fleet investment assets. Our OEM emulsion sprayers feature integrated IoT telematics units that record total square meters sprayed, emulsion volume consumption, thermal profiles, and GPS mapping. Machine operators and rental managers can monitor pump health, receive automated service alerts, and log proof-of-work documentation directly to cloud portals.
By establishing long-term OEM manufacturing agreements with HME TOP Machinery, global hire suppliers secure direct factory pricing, custom branding (private labeling), customized tank geometries to match regional truck chassis (Euro 6, Stage V, or EPA Tier 4 Final), and guaranteed 24/7 technical hotline response.
Proven track record in continuous research, design, and manufacturing of heavy highway equipment.
In-house expertise offering material formulation advice for modified asphalt and bitumen emulsions.
Tailored mechanical, electrical, and aesthetic modifications tailored to local rental markets.
Round-the-clock online assistance paired with rapid on-site technician deployment when needed.
Dedicated regional hubs across Russia, Malaysia, South Africa, Uzbekistan, Kenya, Indonesia, and Sri Lanka.
Direct factory-priced replacement components stocked worldwide to eliminate operational downtime.
Key Information for OEM Procurement Managers, Hire Fleet Operators, and Highway Contractors
Our machines are built with intuitive touch-screen controls, automated self-cleaning cycles, and rugged heavy-duty components. This minimizes operator error, reduces turn-around maintenance time between rental contracts, and ensures high residual asset value over extended hire cycles.
Yes. We offer fully customized frame mountings compatible with international commercial chassis brands including ISUZU, MAN, VOLVO, SCANIA, SINOTRUK, and FAW. We accommodate specific PTO (Power Take-Off) configurations and axle load restrictions.
Our units feature high-efficiency heat exchangers and dual thermal oil circulating jackets around the asphalt pump, filter, and spray bar. This guarantees uniform thermal distribution, preventing emulsion shearing or nozzle clogging even when processing highly viscous modified bitumen.
We provide a 12-to-24 month comprehensive warranty on core structural and hydraulic components. Backed by our global service hubs and remote telematics diagnostics, our engineering team offers 24/7 virtual assistance and on-site operator training.
