SEM 3090F (available in the limited markets)

Equipped with Weichai Tier 3 engine and dedicated manual transmission for mining, ensuring robust torque output and excellent uphill performance.
Modular cooling system featuring a standard 43°C cooling capacity radiator, allowing for prolonged heavy-duty operation.
Optional high-power electronic auxiliary radiator available, along with a sturdy integrated radiator bracket, effectively addressing overheating issues during long-distance and heavy-duty downhill conditions.
Diamond-shaped cargo body design increases volume by 4% compared to a traditional trapezoidal body, shifting the vehicle's barycenter forward to enhance productivity.
Compact front and rear suspension design reduces overall vehicle length, improving maneuverability and operational efficiency by minimizing the turning radius.
Optimized suspension layout lowers loading height, improving loading efficiency while maintaining the sidewall height.

Tier 3 engines, along with optimized supporting systems (fuel, intake and exhaust, electrical, cooling), improve efficiency, reducing fuel consumption under similar working conditions.
Front leaf springs designed with a sliding plate structure, combined with longitudinal thrust rods, reduce the risk of breakage, boosting overall uptime.
The arrangement of lateral and longitudinal thrust between the rear axle and frame enhances lateral stability, effectively reducing failures of both the rear leaf springs and limit plates.
Air filter replacement intervals are extended by 50%, and middle/rear axle maintenance intervals are extended to 2,000 hours to reduce routine maintenance costs.
The dual-chamber fuel tank allows for starting up with winter diesel fuel in low temperatures and regular diesel fuel operation at ambient temperatures, thereby reducing operational costs.

Simplified assembly without subframe ensures a lower center of gravity for enhanced stability.
Rigorously tested through Finite Element Analysis (FEA) and On Machine Stress Analysis (OMSA) verification, the integrated frame design offers a more balanced stress distribution, reducing fatigue points and enhancing long-term durability.
Equipped with a dual-circuit braking system that ensures continued braking effectiveness even if one circuit fails, and large-capacity air reservoir to ensure quick and responsive braking for enhanced safety.
Utilizing exhaust gas circulation technology, the body floor heating system effectively addresses issues with material adhesion, allowing for swift and clean dumping, particularly in cold regions.

Industry-leading hydraulic steering system designed with prioritized steering and safety valves for effortless steering and intuitive driver control.
Newly designed cabin assembly prioritizing ergonomics, ensuring all controls are easily accessible, and enhanced visibility with CAT vision analysis technology.
Stylish dashboard featuring a large LCD screen for clear display of vehicle operation information, including a dedicated fault code query interface.
Air-conditioning equipped with fresh air intake and pressurization for improved sealing and comfort.
Diverse optional features available, including hydraulic retarder with electronic auxiliary radiator, reverse camera, air suspension seat, and multimedia player.
