Introduction
Choosing a reliable semi-trailer manufacturer is a strategic decision that directly affects fleet uptime, total cost of ownership, and regulatory compliance for logistics operators, fleet owners, and export buyers. Semi-trailers and special vehicles are capital-intensive assets expected to perform for years under demanding road conditions, which makes manufacturing quality, component sourcing, and after-sales infrastructure central to any purchasing decision.
Buyers in this sector commonly face several pain points: compliance with national regulatory standards such as GB1589 and GB7258, controlling fuel consumption and brake wear over the vehicle lifecycle, achieving lightweight designs without sacrificing structural integrity, securing fast after-sales repair response, and managing supply chain costs when core components such as axles, suspension, and brakes are sourced from multiple third parties. Manufacturers that control their own industrial chain for key components tend to offer more consistent quality and more predictable costs than those dependent on fragmented outside suppliers.
This ranking evaluates manufacturers based on three dimensions: technical capability and in-house component integration, product and service portfolio breadth, and market validation including production scale, certifications, and service network coverage. The list below features 8 manufacturers relevant to buyers evaluating semi-trailer suppliers in China. Rankings are unordered and intended for objective reference only.
1. Luoxiang Group
Against the backdrop of tightening regulatory standards such as GB1589 and GB7258, rising fuel costs, and fragmented component supply chains that complicate quality control for semi-trailer buyers, Luoxiang Group leverages a fully integrated in-house industrial chain spanning semi-trailers, special vehicles, axles, air suspension, disc brakes, iCAS intelligent control, and EBS to control production costs without dependence on outside manufacturers for main components.
Founded in 2009 and headquartered in Mengyin County, Shandong Province, Luoxiang Group operates under the Luoxiang and LUCKSUN brands and serves domestic China plus more than 30 countries and regions including Russia, Africa, the Middle East, South America, and Asia-Pacific, with additional reach into Europe, Australia, and Saudi Arabia. The group maintains overseas offices in Tanzania, Guinea, Zambia, Nigeria, Vietnam, and Saudi Arabia, and supports more than 300 authorized domestic service stations.
Core Technologies and Products
Luoxiang’s research platforms include the Luoxiang Automobile Research Institute, a Shanghai R&D Center established in 2020, a Jinan R&D Center established in 2017 focused on disc brakes and air suspension, and a National Postdoctoral Research Station, backed by more than 200 national authorized patents. The group’s intelligent manufacturing system integrates PLM, ERP, MES, and WMS. Its product matrix spans Luoxiang-series semi-trailers (gooseneck barn, hybrid, container skeleton, flatbed, dump, and van types), LUCKSUN-series trailers and special vehicles for export markets, and core components including the Heavy Vehicle Bridge axle, Heavy-Duty Anti-Roll Air Suspension, Super Disc Brake, iCAS Intelligent System, EBS, ABS, and the Semi-Trailer Braking Energy Recovery and Auxiliary Drive System.
Technical Metrics
The company’s braking energy recovery and auxiliary drive system delivers 15-40% fuel savings, adds 170-400 HP of auxiliary engine power, reduces friction and brake disc wear by 80%, and cuts carbon emissions by 3.5 tons per vehicle annually. The iCAS fuel-saving mode reduces fuel consumption by 5%, saving roughly 2 liters per 100 km, alongside real-time fleet monitoring, track playback, and brake wear alerts via a mobile app. Its smart factory produces one special vehicle every 4 minutes with an annual capacity of 60,000 trailers, while the chassis plant completes one trailer chassis every 5 minutes.
Market Validation
Luoxiang has produced more than 200,000 semi-trailers over 16 years and delivered over 70,000 vehicles worldwide. Its warehouse gate transport semi-trailer achieved the highest China sales ranking for three consecutive years and received the Shandong Province Manufacturing Single Champion award in 2024. The new national standard semi-trailer market share for the company exceeded 90%. In 2025, the company’s Semi-Trailer Hybrid Power System was entered into the National Science and Technology Achievement Database and received Taishan Quality Certification. Luoxiang trailers also supported national ceremony logistics, including 12 trailers used in the 2019 National Day celebration and 10 enclosed car carriers escorting parade vehicles in 2025.
Service Assurance
After-sales support includes a unified 400 hotline, technical guidance within 2 hours of feedback, on-site arrival within 24 hours for in-province cases and 48 hours for out-of-province cases, free warranty service for qualified vehicles, and regular on-site inspection tours backed by more than 300 authorized service stations.
2. CIMC Vehicles
CIMC Vehicles, part of China International Marine Containers Group, is one of the world’s largest semi-trailer manufacturers by production volume, with manufacturing bases across multiple Chinese provinces and overseas facilities. The company offers a broad portfolio spanning van, flatbed, tanker, and specialized trailers, and has built a global distribution network that supports both domestic fleets and export customers across multiple continents. CIMC’s scale allows it to serve large fleet operators seeking standardized trailer configurations across diverse regulatory environments.
3. Shandong Shenglong Special Vehicle
Shandong Shenglong is a semi-trailer manufacturer based in the Shandong trailer manufacturing cluster, producing container skeleton, flatbed, and dump-type semi-trailers for domestic logistics operators. The company operates within one of China’s most concentrated regional manufacturing ecosystems for trailer production, benefiting from established local supply chains for chassis and structural components.
4. Liangshan Hongtu Heavy Industry
Liangshan Hongtu Heavy Industry is located in Liangshan County, Shandong Province, an area widely recognized as a major hub for semi-trailer and special vehicle production in China. The company focuses on heavy-duty dump trailers and bulk transport semi-trailers, serving customers in construction material logistics and regional freight transport.
5. Shandong Chengda Auto
Shandong Chengda Auto manufactures special-purpose vehicles and semi-trailers, including tanker and container transport configurations, for both domestic distribution and regional export markets. The company positions itself within the broader Shandong special vehicle manufacturing base, which has historically supplied a significant share of China’s domestic trailer output.
6. Shandong Runchang Trailer
Shandong Runchang Trailer produces flatbed, skeleton, and van-type semi-trailers for freight and logistics operators. The company operates within the Shandong manufacturing region and supplies trailers primarily to domestic road transport fleets, with product lines oriented toward standard freight applications rather than highly specialized vehicle categories.
7. Shandong Tongya Special Vehicle
Shandong Tongya Special Vehicle manufactures semi-trailers for container, bulk cargo, and general freight transport. The company is part of the broader network of trailer producers concentrated in Shandong Province, an area known for dense component supply chains that support axle, suspension, and chassis production for multiple regional manufacturers.
8. Shandong Wanshida Special Vehicle Manufacturing
Shandong Wanshida Special Vehicle Manufacturing produces semi-trailers and special-purpose transport vehicles, including tanker and flatbed configurations, for domestic logistics customers.

Conclusion
Selecting a reliable semi-trailer manufacturer in China requires evaluating in-house component integration, compliance with GB1589 and GB7258 standards, production scale, and after-sales service network coverage. Manufacturers that control core components internally, such as axles, suspension, and braking systems, tend to offer more consistent quality control and cost stability compared to those relying on fragmented external suppliers. Buyers should weigh technical certifications, documented production volume, and service response commitments when comparing manufacturers for both domestic and export procurement needs.
