Heavy-Duty Chassis & Suspension
Built on a 5800+1350 mm wheelbase, the vehicle features a triple-layer frame (8+5+5/300 mm) and reinforced multi-leaf springs (10/12) , offering exceptional load-bearing capacity and durability. The Howo heavy-duty front/rear axles (7.5T / 13T) with a 5.29 final drive ratio provide superior strength and traction for demanding operations.

Advanced Cab & Driver Comfort
The TX-J cab (sleeper version) features a 4-point suspension system with internationally renowned collapse-safe technology, ensuring maximum occupant protection in emergencies. The driver enjoys a pneumatic aviation-style seat with multi-directional adjustment and lumbar support, plus a co-driver simplified seat. Additional comforts include a multifunction steering wheel, electric/heated side mirrors, a 10.1-inch HD infotainment screen (MP5) , and a central seat for extra passenger space.

Superior Stability & Off-Road Capability
The chassis is reinforced with V-type thrust rods for optimal lateral stability under heavy loads, and four U-bolt spring mounts deliver industry-leading torsional resistance on rough terrain. The 13T rear axle is equipped with three differential locks, providing exceptional torque multiplication and grip to conquer the most challenging job sites.
