CAMC
The CAMC 4 × 2 dock tractor is a specialized operation equipment customized for short distance transportation in ports, logistics parks, and industrial parks. It focuses on high-frequency cargo transfer scenarios in fixed areas and has become a benchmark model for efficient logistics transportation in the field due to its strong power, compact body, and adaptability to working conditions. It is suitable for continuous operation needs at all times.
The vehicle is equipped with a high-performance powertrain, with a maximum power of 360kW and a peak torque of 2100N · m. The power output is strong and linear, making it easy to handle the full load start stop and continuous traction needs of containers and heavy materials. Specially optimized low-speed control logic for high-frequency start stop conditions in the field, with precise and gentle operation, eliminating power jerks, and significantly improving the smoothness and overall transportation efficiency of on-site transfer operations.
The whole vehicle adopts a short wheelbase, integrated compact layout, exquisite body size, small turning radius, and can flexibly shuttle in port passages, park alleys, and narrow areas of factories. The equipment has strong compatibility and can be directly connected to on-site specialized trailers such as container flatbed trailers and heavy material transport vehicles. It can quickly connect operations without the need for secondary restructuring and is suitable for various types of cargo transportation needs.
The entire vehicle is equipped with a comprehensive active and passive safety protection system, which accurately avoids operational risks such as blind spot operations and close range vehicle movements, ensuring the safety of personnel, equipment, and goods. Relying on the mature manufacturing process of CAMC, the core components have a low failure rate, and the structure is wear-resistant and resistant to manufacturing. It is suitable for harsh working conditions such as high dust and continuous operation, providing efficient, safe, and low-cost exclusive solutions for industrial and port logistics.

1. High power and strong traction, outstanding heavy-duty performance
With a maximum power of 360kW and a peak torque of 2100N · m, it has sufficient power reserve and strong continuous traction performance when starting at full load, making it easy to handle heavy container and industrial heavy-duty material transfer tasks in ports.
2. Compact body design, flexible passage in narrow areas
Short wheelbase lightweight layout, small turning radius, responsive steering, perfect for narrow passages in port areas, dense yards in logistics parks, and restricted spaces inside factories, with higher shuttle scheduling efficiency.
3. Full trailer compatibility, seamless and fast connection
The original factory standardized traction interface can directly match various types of on-site trailers such as container flatbeds and heavy materials, without the need for modification and debugging, with fast docking and greatly reducing the preparation time for grouping.
4. Customized low-speed calibration, smooth high-frequency operation
Optimizing the electronic control logic for frequent start stop and low-speed vehicle movement in the field, the power output is linear and soft, the operation is precise and easy to control, reducing the driver's operating intensity and effectively improving the daily high-frequency transportation efficiency.
5. Comprehensive security protection, worry free on-site operation
Equipped with a complete safety protection system, it avoids common risks in the field such as blind spot collisions and overload loss of control. The vehicle has strong durability and convenient maintenance, and is suitable for 24-hour uninterrupted high-frequency attendance, with lower downtime losses.

Pre-Startup Inspection:Confirm no obstacles around the vehicle, check the power system’s energy status, turn on safety warning lights before starting the vehicle.
Low-Speed Operation:Control the speed within the in-yard speed limit; switch to "Precision Mode" when connecting cargo, completing alignment with low speed and small torque.
Trailer Connection:When connecting to in-yard special trailers, confirm the locking device is fully engaged; after connection, gently step on the accelerator to test connection stability.
Parking After Operation:Park in the designated area, pull the parking brake and turn off the power system, then disconnect the charging/energy supply interface before leaving the vehicle.
1. Southeast Asian container port operators
“Our yard passage is narrow, and the daily transfer frequency is extremely high. This CAMC 4 × 2 dock tractor has a flexible body, high power enough to tow fully loaded containers, smooth low-speed operation, and easy driver operation. Trailer docking does not require modification and has high stability, effectively improving the overall turnover efficiency of our port area. ”
2. Large industrial logistics parks in the Middle East
“There are many alleys and limited space inside the park, making this vehicle flexible in turning and powerful, fully suitable for our heavy material transportation needs. The vehicle has a low failure rate, good dust resistance, and is suitable for local dusty working conditions. The after-sales spare parts supply is timely, making it the ideal main vehicle for logistics fleets in the park. ”
