Road-water transport - EAX(SUZHOU)TECHNOLOGY CO.,LTD.

Industry Introduction

Combined road and water transport is the core mode connecting ports, locks and land transportation, especially in inland river hubs (such as the Yangtze River and Pearl River basins), where it undertakes the "last mile" transshipment of bulk goods.

Short-distance transport upstream and downstream of the lock needs to operate in a high-frequency (10-15 trips per day), heavy-load (load ≥ 49 tons) and fixed-route environment (port-yard-lock area).

As of 2025, fuel-powered tractors will still account for more than 70% of the short-distance ship lock market, but their high pollution and low efficiency pain points are increasingly in conflict with the "dual carbon" policy and the port greening goals.

Industry Pain Points

Heavy fuel consumption burden

A fuel tractor consumes 45-50L of fuel per 100 kilometers. The average daily fuel cost for an operation of 200 kilometers is 720-800 yuan (oil price is 8 yuan/L), accounting for more than 40% of freight income.
Complex maintenance

The average annual maintenance cost of the engine is 80,000 yuan, the DPF after-treatment system needs to be cleaned every 5,000 kilometers (cost 3,000 yuan/time), and the high humidity environment aggravates chassis corrosion, increasing the average annual maintenance cost by 20,000 yuan.
Exceeding carbon emissions standards

A single gasoline vehicle emits 120 tons of carbon dioxide per year and faces the port carbon tax and the "National IV Ban" policy (fully implemented in the core port area in 2025) 510.
Loss of right of way

The restricted areas for fuel vehicles in cities along the river have been expanded, and the ban on roads connecting locks has increased detour distances by 20%.
Inefficient energy replenishment

Refueling requires leaving the operation area and going to a gas station outside the port, which takes 30-60 minutes per trip (including queuing for both ways), reducing the average daily effective operation time by 30%210;
Power interruption risk

AMT transmissions experience power interruptions during gear shifts, making it easy for the vehicle to slip when climbing a slope with a heavy load, leading to cargo overturning or ship lock delays (annual accident rate exceeds 10%)3.

Solutions

Economic breakthrough

The full-cycle cost is reduced by 40%.
Energy consumption dropped sharply

The electricity cost is 0.3 yuan/km vs 3.6 yuan/km for gasoline vehicles. A single day of 200 kilometers saves 660 yuan, and an annual saving of 240,000 yuan210.
Vehicle-battery separation reduces costs

Battery leasing reduces the purchase price of a vehicle by 30% (for example, the price of a XCMG electric vehicle is RMB 680,000 vs. RMB 980,000 for a gasoline vehicle), thus avoiding the risk of battery degradation.
5-minute rapid battery replacement

Mobile battery swap stations in port areas/gates (such as the Qiyuanxin power solution) match the high-frequency operation rhythm and increase the energy replenishment efficiency by 6 times compared to gasoline vehicles.
Uninterrupted power

The dual-motor drive has a peak torque of 4500N·m, and heavy-load starting is 30% faster, eliminating the need for slipping when climbing a slope in a lock.
Intelligent scheduling linkage

The vehicle computer is connected to the lock management system to predict the lock opening time and automatically plan energy replenishment, reducing the false lock rate by 90%.
Zero emission compliance

A single vehicle can reduce carbon emissions by 120 tons per year, is exempt from carbon tax and enjoys port subsidies (such as priority dispatch for green-licensed vehicles at Zhoukou Port).
Full-time right of way

Green license plates ignore traffic restrictions, and people can freely pass through the road connecting the locks, and the detour distance is reset to zero.
