"Mother and child cars" go out on the street! This wave of heavy truck "nesting doll" operations, saving is earning

  • 2025.09.17

Trinity heavy truckThe launch of Jiangshan 430 charging mother and child car and Jiangshan 425 replacement electronic mother car is an efficient logistics solution for the scenario of "full to empty and back" scenario. Through a unique combination design, they are "fully loaded with two vehicles" on the outbound trip and "one car on the back trip", which is outstanding in reducing operating costs and improving transportation efficiency.


Jiangshan 430 charging mother and child car

The height of the sub-car is ≤ 2.8m, and the height of the superimposed mother car is ≤4m, so you can rest assured on the road. The mother and child vehicles can replenish each other's power to achieve efficient operation of "full and empty return", especially suitable for routes with stable supply of goods, fixed destination, and high probability of empty driving on the return journey, such as coal transportation, some special line logistics, etc.




Jiangshan 425 replaced with an electronic mother car

The model provides battery "only replacement and no repair" service, and the MTB Magic Tower battery warranty is 8 years or 4,000 cycles; The vehicle has a dead weight as low as 10.4t, which pulls 100-300kg more than its friends and earns 6,000 yuan more per 100,000 km, which is suitable for high-frequency and high-intensity operations, and has strict requirements for operational efficiency and human-vehicle ratio.




1. Reduce costs and increase efficiency

1. Efficient operation

An excellent solution for the "full and empty return" scenario, "two cars become one car" on the return trip

2. Double cost savings

Drive 100,000 km a year, save 32,000 yuan in electricity bills + 100,000 yuan in tolls




2. Worry-free battery life

1. Intelligent power replenishment, worry-free battery life

The mother and child cars can replenish each other's power, and the return mileage can reach 650km

2. One-click switching, convenient and efficient

The power supply can be switched with one click on the way, which is simple, convenient and efficient to operate

3. Prevent error and blind insertion, safe and worry-free

The connection harness is error-proof, allowing blind insertion without the need for special tools




3. Safety protection

1. Double safety operation

It adopts a double relay design, and the operation is not electrified, which effectively ensures the safety of personnel operation

2. Triple seal protection

The interface adopts silicone gasket + waterproof rubber ring + plug cover triple protection, which is effectively dustproof and waterproof in harsh environments

3. Long-lasting and reliable connection

The junction box quick-plug connector supports 5000 times of plugging and unplugging > without attenuation; Built-in temperature monitoring points, high-voltage interlock real-time detection, ensure safe and reliable connections

The combination of these two sub-mother vehicles of Sany Heavy Truck has achieved the operational benefits of "1+1>2" through the clever design of physics and the innovation of energy replenishment mode, and is an excellent solution for reducing costs and increasing efficiency in specific transportation scenarios.
