Truck Cab Front Anti-collision Beam Protective Bumper 2809210-C0111 Is Suitable for Dongfeng Tianlong KC Heavy-duty Truck

The 2809210-C0111 Front Lower Protection Assembly, commonly known as the front under-run protection bar or lower front bumper beam, is a structural safety component designed to enhance occupant protection in frontal collisions involving light vehicles. Installed beneath the front grille and radiator support frame of Dongfeng heavy-duty trucks, this assembly serves two primary functions:

Prevents smaller vehicles from underriding the truck during low-speed impacts
Absorbs and distributes impact energy to protect critical under-hood components such as the radiator, intercooler, and air conditioning system
Engineered from high-strength steel with optimized cross-sectional geometry, the 2809210-C0111 meets China's national safety standard GB 26511 for commercial vehicle front lower protection. It is widely used on Dongfeng Tianlong KC, KL, and KX series heavy-duty chassis operating in construction, mining, and long-haul logistics where collision risks are higher due to complex road conditions.
