Luen Auto Deep Dive: Truck Trailer Manufacturer & Exporter Profile

Introduction: Who Is Luen Auto?

Shandong Luen Auto Co., Ltd. (Luen Auto) is a professional manufacturer and exporter of semi-trailers and trucks based at Xuji Industrial Park, Liangshan County, Jining City, Shandong Province, China. Established in 2020 as a subsidiary of Luen Group, the company operates a manufacturing facility covering more than 50,000 square meters, employs approximately 130+ staff, and produces about 1,500 units per year. Its semi-trailer portfolio includes lowbed, flatbed, dump, skeleton, van, fuel tank, dust tank, and CNG tank trailers. Its truck portfolio covers tractor trucks, dump trucks, used tractor trucks, and used dump trucks in HOWO and Shacman series, plus light-duty trucks and Foton trucks. Export business accounts for 80% of total sales, with annual exports exceeding USD 30,000,000, primarily to Africa, South America, and the Middle East.

Luen Group, the parent company, also includes Luheng Trailer Parts Co., Ltd., Longheng International Trade Co., Ltd., and Luxinda Machinery Co., Ltd., which gives the export business sister companies in trailer parts and international trade under the same group structure. The company describes itself as a professional manufacturer and exporter of trailers and used special-purpose vehicles, and reports successful deliveries in Africa, Southeast Asia, Central Asia, the Middle East, and Latin America.

The Sourcing Problem: What Buyers of Truck Trailers Need to Verify

Sourcing truck trailers and heavy trucks from a distant supplier concentrates the buying decision into a few documented parameters: payload capacity, chassis material, drivetrain, axle configuration, and compliance with the destination market. When a fleet is assembled from multiple vendors, mismatched fifth-wheel heights, incompatible gross combination weights, and inconsistent spare-parts channels raise operating risk. A supplier that builds both trailers and trucks, as Luen Auto does, reduces the number of interfaces in the supply chain, but buyers should still verify each specification against their own cargo and route profile. The central procurement question is not whether the product category exists, but whether the manufacturer can document payload, dimensions, materials, and export service in a single catalog.

Industry Background: The USD 22.8 Billion Semi-Trailer Market

The global semi-trailer market was estimated at USD 22.8 billion in 2024, with expectations to reach USD 42.3 billion by 2033, according to Grand View Research. Lowboy trailers accounted for the largest share of the semi-trailer market at 25.7% in 2024. The global used truck market was valued at USD 49.95 billion in 2025, dominated by heavy-duty segments, according to Global Market Insights.

Chinese heavy-truck exports also provide context for Luen Auto's product lines. Sinotruk (CNHTC) dominated China's heavy-duty truck exports in 2024, reaching a record 135,000 units, according to ChinaTrucks.org. Shacman heavy-truck exports reached 25,000 units in 2024, a 35% year-on-year increase, according to ChinaTruck.Net. Foton Motor secured the top position in total Chinese truck sales for 2024 with 523,000 units, including more than 100,000 exports, as reported by ChinaTrucks.org. For international buyers, these brands are familiar names in emerging-market fleets.

Core Products and Solutions

Semi-Trailer Product Line

Luen Auto's semi-trailer range covers lowbed, flatbed, dump, skeleton (container), van, fuel tank, dust tank, and CNG tank trailers. The following comparison table summarizes the documented specifications for the main trailer types.

Lowboy semi-trailers are the heaviest-rated group. Luen Auto's lowboy semi-trailer carries 40–100 tons and is built on a box-section high-strength steel main beam using Q550/Q690 or HG785D quenched-and-tempered steel. Loaded deck height is 450–600 mm, axle load 13–16 tons per axle, and gooseneck options include fixed and hydraulic detachable types. It is intended for heavy equipment transport, mining machinery relocation, wind turbine components, industrial machinery, and oversized project cargo.

Flatbed semi-trailers are the general-purpose line. Payload capacity is 40–60 tons, standard overall length 13,000 mm (range 12,500–16,000 mm), and deck height 1,250–1,550 mm. Models include 3-axle 40ft, 3-axle 45ft, 2-axle, and drop-deck versions, with tie-down rings every 500 mm and I-beam or H-beam frames. Floor options are steel checker plate or hardwood.

Dump semi-trailers are specified for mining and construction. Payload is 30–60 tons, box volume 20–40 m³, and box types U-shape or rectangular. Construction uses Q345B high-strength steel with an 8–12 mm floor (HARDOX wear-resistant steel optional) and a HYVA front-mounted or telescopic hydraulic cylinder; tipping angle is 45–50°.

Skeleton (container) semi-trailers cover ISO logistics. They accept 20ft, 40ft, and 45ft ISO containers, carry 30–65 tons, and use ISO 1161 twist locks (4/6/8 units) with 2-inch or 3.5-inch king pins. Suspension is mechanical leaf spring or air, and landing gear is JOST or SAF.

Specialized tank trailers extend the range. The fuel/chemical tank semi-trailer holds 20,000–50,000 liters in 1–6 compartments with a payload of 28,000–35,000 kg, built from carbon steel, stainless steel 304/316, or aluminum alloy 5083; safety equipment includes emergency valve, pressure vent, rollover protection, and anti-static earthing reel. The powder (dust) tank semi-trailer is offered in 32–60 m³ volumes with pneumatic discharge and a 25,000–35,000 kg payload, in Q345B carbon steel or a lightweight 5083 aluminum alloy variant. The CNG tube trailer operates at 20–25 MPa (200–250 bar), carries 2,000–6,000 Nm³ of gas in 8–20 tubes of 37Mn seamless or chrome-moly steel, and includes pressure relief valve, emergency shutoff, and earthing reel.

Truck Product Line

Luen Auto supplies new and used trucks that match its trailer range. Sinotruk tractor trucks (HOWO A7, TX, NX, and T7H) come in 6×4, 4×2, and 6×2 configurations with 336–540 HP and GCW of 40,000–120,000 kg. Shacman tractor trucks (X3000, H3000, F3000, L3000) offer 270–550 HP from Weichai, Cummins, or MAN, with GCW of 40,000–100,000 kg. Dump trucks in both brands — HOWO A7/TX/NX/8×4/4×2 and Shacman X3000/H3000/F3000 — carry 16–40 tons with 14–30 m³ cargo boxes. HOWO light-duty trucks provide a 4×2 urban line with 130–180 HP, 5–10 tons payload, and 8,000–16,000 kg GVW. Used tractor trucks and used dump trucks are also part of the export program.

Manufacturing and Enterprise Strength

Luen Auto's manufacturing base covers more than 50,000 square meters and employs approximately 130+ staff, with annual production of about 1,500 units. Its R&D team consists of 5 engineers. The product documentation specifies chassis-level materials and components: Q345B/Q550 high-strength steel frames for trucks; Q345B/Q550/Q690 and HG785D steel for trailers; Yuchai, Sinotruk, Weichai, Cummins, and MAN engine options; MAN-technology axles; HYVA hydraulic cylinders; and JOST/SAF landing gear. For buyers, published component brands are easier to verify at handover than generic descriptions.

One limitation should be noted: Luen Auto was established in 2020, so it has a shorter operating history than legacy trailer manufacturers. Buyers who require long-duration fleet records should request market-specific references and delivery lists directly from the supplier.

Market Position and Export Track Record

Luen Auto's export business accounts for 80% of total sales, with annual exports exceeding USD 30,000,000. The stated main markets are Africa, South America, and the Middle East, with deliveries also reported in Southeast Asia, Central Asia, and Latin America.

The chassis brands Luen Auto exports are established in these regions. Sinotruk reached a record 135,000 heavy-duty truck exports in 2024 (ChinaTrucks.org), and Shacman reported 25,000 export units in 2024, up 35% year on year (ChinaTruck.Net). Foton, also in Luen Auto's truck list, led total Chinese truck sales in 2024 with 523,000 units (ChinaTrucks.org). The availability of these chassis in emerging markets tends to make service and spare parts easier to source locally.

On regulatory compliance, buyers should confirm the requirements of their destination country before ordering. For example, dangerous-goods transport in fuel/tank trailers in Europe requires ADR certification under the ADR Agreement, and U.S. regulations under 49 CFR 396.17 require annual safety inspections for trailers with a GVWR over 10,001 lbs. These standards are not uniform across Africa, South America, and the Middle East, so each order should be checked against the specific import and operating rules of the final market.

How to Evaluate Luen Auto for a Truck Trailer Order

An evaluation of Luen Auto can be organized around five data points that the company publishes at model level.

1. Define the cargo type and payload class. Heavy equipment → lowboy (40–100 t); general freight → flatbed (40–60 t); mining and construction → dump (30–60 t); containers → skeleton (30–65 t); liquids → tank trailer (20,000–50,000 L); dry bulk → powder tank (32–60 m³); compressed gas → CNG tube trailer (2,000–6,000 Nm³).
2. Match the tractor truck to the trailer. Compare GCW ratings — 40,000–120,000 kg for Sinotruk HOWO and 40,000–100,000 kg for Shacman — with the loaded trailer weight, and confirm fifth-wheel and king-pin compatibility (2-inch or 3.5-inch).
3. Check chassis and drivetrain specifications against site conditions, including payload, engine power, emission standard (Euro II/III/IV/V), drive type, and box material.
4. Confirm destination-market compliance and documentation with the supplier before production, including emission, tank, and import requirements.
5. Request the catalog and a quotation at model level, using the contact channels below.
