The T7H cabin includes a full-size sleeper berth, making it suitable for applications requiring overnight stays. Both models are available in 6x4 and 8x4 drive configurations for dump truck applications.
The chassis of the T7 and T7H models is constructed from high-strength steel with reinforced cross members, providing exceptional durability for heavy-duty applications. The suspension system features parabolic leaf springs with shock absorbers, delivering a balance of load-carrying capability and ride comfort. The braking system includes dual-circuit air brakes with ABS and engine exhaust brake as standard equipment.
Load capacity for the T7/T7H dump truck ranges from 25 to 40 tons, with cargo body volumes of 18-30 cubic meters depending on the configuration. The robust powertrain and chassis design make these models ideal for the most demanding mining and large-scale construction operations.
