The ZT105 utilizes a riveted frame with the longitudinal beam riveted using 12+12 double-layer superimposed groove-shaped bending plates and 6 cross beams, providing advantages like good forming technology and suitability for mass production. The frame material has been upgraded from 510L to 610L for better fatigue resistance, and the design benefits from computer-aided design and finite element optimization analysis.

The front suspension adopts a dependent suspension with a hydro-pneumatic and multi-link mechanism, ensuring reliable wheel positioning and a stable, comfortable driving experience. The middle and rear axles are connected to the frame via leaf springs, allowing the truck to adapt to varying loads and road conditions with high reliability.

The truck features an engine with advanced, energy-efficient technology. The cooling system includes a split radiator with strong anti-seismic ability and easy maintenance, an imported air fan for large air volume and low power consumption, and the entire vehicle is designed with a large heat load capacity.
