Supplies specialized oilfield equipment, truck-based vehicles, and automation services to dealers serving oilfield-service companies. Most revenue comes from equipment and vehicle sales, while final vehicle manufacturing depends on qualified third-party partners.
Designs and assembles specialized oilfield equipment, automation solutions, and vehicles including oil-pumping, well-repair, fracturing, flushing, boiler, cementing, logging, liquid-nitrogen pumping, and rescue trucks. It develops core equipment and components internally while sourcing or outsourcing most other components.
Earns most revenue from oilfield equipment and vehicle sales; automation work combines software development, tailored functions, training, testing, and debugging. Customers are principally dealers serving oilfield-service companies, while revenue, personnel, and long-lived assets are concentrated in China. Its competitive approach centers on customization, product breadth, design and delivery speed, automation content, supplier relationships, and after-sales service.
Relies on qualified manufacturers to complete specialized vehicles and obtain regulatory announcements because it did not hold the relevant production qualification as of its latest annual report.
