Excellent technology: the main components are processed by advanced equipment, the longitudinal beam is made by automatic submerged arc welding, and the assembly machine is used to accurately assemble the axle and leaf spring.

With its excellent product quality and technical strength, Tongya Automobile has successfully obtained the OTTC certification for Russian vehicles, further opening the door to the Russian market.

FAW has placed an order for oil tanker semi-trailers with Tongya Automobile Co., Ltd., the Liangshan-based semi-trailer and tanker manufacturer that has been building trailers in Shandong since 1982 — and the completed units have already left Tongya's own plant. Because Tongya designs, fabricates, welds, coats and tests every trailer inside its own factory on a 400,000 m²-plus site with 1,200-plus pieces of equipment, the order moved from confirmation to dispatch on a compressed lead time rather than waiting on outside fabricators, coating subcontractors or third-party assembly.

Tongya Automobile Co., Ltd. has dispatched a new batch of aluminum alloy fuel tanker semi-trailers from its 400,000 m² production base in Liangshan County, Shandong, to buyers serving African mining markets. Each 50,000-litre unit has a tare weight of 7,500 kg, so every trip delivers more diesel and fewer trips are needed to keep remote mine sites running.

When a fleet operator asks where to buy a dependable semi-trailer straight from a factory, one answer keeps coming up in China's trailer industry: TONGYA AUTO (Tongya Automobile Co., Ltd). Founded in 1982 in Liangshan, Shandong — one of China's largest special-vehicle manufacturing hubs — the company has grown into a full-scale truck-trailer manufacturer that integrates product design, research and development, production, and sales under one roof, with an annual output of more than 16,000 units.
