The ZT115A boasts a highly durable chassis featuring a riveted frame. The side member is bent with 12+12 double-layer high-strength steel plates, including local 4-layer reinforcement for critical stress points. Utilizing 610L material, the frame offers superior strength and excellent fatigue resistance. Its unique frame belly height of 500mm is the highest in the industry, and the entire structure is optimized using computer-aided design and finite element analysis to guarantee reliability under extreme mining conditions.

The truck is equipped with a sophisticated suspension system for reliable wheel alignment and driver comfort. It features front non-independent suspensions combined with hydro-pneumatic and spring + multi-link suspensions. This configuration effectively alleviates the impact from uneven road surfaces, significantly attenuates vibration, and ensures stable and comfortable driving. The middle and rear axles connect to the frame via leaf springs and tie rods, delivering high reliability and adaptability to changing load and road conditions.

The vehicle is driven by an advanced engine (Model YCK13580-T400) with a Rated power of 426 kW, adhering to the China Non-road Stage III emission standard. The system is designed for high efficiency and energy saving. Engine protection is maximized via a three-stage filter for the fuel oil supply system, fully safeguarding the engine and the high-pressure common rail injection system. The machine's thermal load capacity is high, utilizing an integral radiator that offers high shock resistance and simplified maintenance.
