  • Developed using the complete cab technology introduced from Daimler-Benz.
  • The NG80 cab features a semi-floating suspension system with high structural rigidity and energy absorption, providing enhanced driver protection.
  • Manufactured with high-strength steel panels through integrated stamping, combined with a multi-cavity structural design for increased rigidity.
  • Successfully passes pendulum impact testing and complies with EU crash safety certification standards. Ideal for engineering applications and mixed operating conditions

  • Developed in collaboration with EDAG Germany and benchmarked against Daimler-Benz standards, the V3 cab is a wide-body design created through a forward engineering process.
  • The V3 cab features a four-point floating suspension system, offering high structural strength and energy absorption while enhancing overall driving comfort.
  • Built with high-quality steel panels through full-body integrated stamping, along with a multi-cavity structure that increases cab rigidity.
  • Successfully passes pendulum impact tests and complies with EU crash safety certification standards. Optimized for long-distance highway transport applications.

Developed using Daimler-Benz technology, the frame features a variable-section, fish-belly-shaped composite beam design. The inner and outer frame rails are formed through a single-pass stamping process, delivering outstanding load-bearing performance. The result is a frame system renowned for its exceptional durability and structural strength, widely trusted in demanding heavy-load applications.

  • Beiben was the first in China to adopt Daimler-Benz’s dual reduction drive axle technology.
  • The axle housing is made from ductile cast iron and manufactured as a single integrated casting for enhanced strength and durability.
  • According to tests conducted by nationally accredited institutions, the axle housing can withstand 2.5 times the rated load for over 1.17 million fatigue cycles without cracking.

  • Equipped with an integrated balance suspension system developed using Daimler-Benz technology.
  • The suspension adopts a combination of leaf springs, balance suspension, thrust rods, and stabilizer bars to ensure stability under load.
  • Delivers high load-bearing capacity and excellent long-term reliability.

  • All vehicle models are equipped with Weichai engines, known for their strong reliability and high-performance output.
