Delong 6×4 Tractor

Delong 6×4 Tractor

The Delong 6×4 Tractor is a multi-purpose heavy-duty transport vehicle designed for the global market, covering three major operating scenarios: economical, standard-load long-haul, and efficient logistics. It is widely applicable to container transport, trunk general cargo, coal and gravel transport, heavy-duty mining, and cross-border long-haul transportation. This model integrates mature German chassis technology with a domestically produced high-quality powertrain, balancing lightweight standard-load and reinforced heavy-duty conditions. It boasts core advantages such as robustness, fuel economy, convenient maintenance, and adaptability to all environments, making it the most widely used and cost-effective 6×4 tractor model in the overseas heavy-duty truck market.
The vehicle utilizes a high-strength integrated through-frame chassis. The powertrain has undergone extensive market testing and supports both diesel and natural gas fuels. The cab is available in standard, high-roof, and high-roof flat-floor versions to meet the needs of economical short-haul heavy-duty and high-end long-haul dedicated line transportation. The vehicle features a simplified and redundant electronic structure, highly interchangeable parts, comprehensive global distribution, low maintenance costs, and stable operation in high and low temperatures, mountainous areas, and unpaved roads, adapting to regulations in multiple countries and complex road conditions.
