Hardcore Technology Builds a Safe Fortress! This is the Responsibility of Dongfeng Liuzhou Motors, a State-Owned Enterprise with a 71-Year Heritage
2025-08-15
As a state-owned enterprise with a history of 71 years, Dongfeng Liuzhou Motors has always adhered to the corporate culture and original aspiration of "serving the country and the people", regarding safety as the lifeline of its development. In the commercial vehicle sector, the Chenglong Trucks is not only an efficient and reliable transportation tool, but also a model of Dongfeng Liuzhou Motors fulfilling its social responsibilities with cutting-edge technology. The cab of the Chenglong Trucks adopts an innovative keel frame body structure, aiming to build a solid "safety skeleton" for drivers and passengers, and has always been highly praised by users. So, how exactly does this set of " skeleton " play a protective role? Today, let's uncover together the mystery of how Chenglong Trucks build a mobile safety fortress with cutting-edge technology!
Keel frame - Building an efficient force transmission path
The "keel frame" of the Chenglong Trucks is the cornerstone of the cab's ultra-high load-bearing capacity and passive safety performance. The quintessence lies in the meticulous design of the layout of longitudinal and transverse beams, joints and cross-sectional structures, and the construction of multiple parallel force transmission paths for different working conditions to achieve high force transmission efficiency.
The cab frame forms a scientific and reasonable closed ring structure in both the vertical and horizontal planes, significantly enhancing the overall strength and rigidity. When encountering external impacts such as collisions and severe jolts, the keel frame can efficiently disperse the impact force across multiple paths, greatly reducing local stress concentration. At the same time, even in the event of local damage, the vehicle body can still maintain sufficient overall rigidity and load-bearing capacity, reserving valuable living space for the driver and passengers.
Steel bars and iron bones - 30% high-strength steel application, creating armor-level protection
If the keel frame is the "safety skeleton" of the Chenglong Trucks, then the high-strength steel, which leads the industry by as much as 30%, is the "steel and iron skeleton" that builds this skeleton. The carefully selected high-strength steel materials and the precise keel frame structure design complement each other, jointly forming a complete "protective armor". This armor not only endows the vehicle body with outstanding durability, allowing it to handle the harsh challenges of daily transportation with ease, but also transforms into a solid barrier safeguarding the lives of drivers and passengers in the moment of an accident.
Thoroughly tempered more than 30 real vehicle collision tests, with EU certification providing comprehensive protection
The body of the Chenglong Trucks is forged to world-class safety quality standards, and its safety performance has undergone rigorous practical verification. The core objective of the all-round collision safety design is to ensure the complete living space for drivers and passengers to the greatest extent in an accident.
The vehicle body has undergone over 30 real vehicle crash tests, including frontal collisions, A-pillar collisions, side collisions, rear collisions, and roof crush tests, covering various accident scenarios. And it has successfully passed the globally recognized strict standard - the ECE R29 safety certification of the European Union, marking that its safety performance has reached the international advanced level.
With outstanding safety and reliability, Chenglong Trucks have achieved remarkable results in top-level events such as the China Truck Open.
