In terms of the suspension system, the Intra Drum Brake Axle (RST design) is engineered with precise X values and air spring bracket dimensions to perform efficiently under different loading conditions. In both unloaded and loaded states, the distances are optimized within a range of 245 to 395 mm to ensure better stability.

Additionally, the thickness of reinforced components and the ST and FH dimensions vary between 80 and 150 mm, resulting in increased strength and extended service life of the system. Altogether, these features enable the axle to تحمل heavy loads while maintaining high durability, safety, and reliability, making it an ideal choice for road transport fleets and heavy industrial projects.
