Xi’an, Shaanxi, China – September 3, 2026

SHACMAN M5000E4×2 Under-Chassis 400kWh Electric Axle Port Tractor is specifically designed for high-intensity, high-frequency scenarios such as port drayage, short-haul intermodal transport, and logistics parks. By combining an under-chassis battery architecture with a highly integrated electric drive axle, it directly addresses the traditional pain points of electric heavy Trucks—heavy curb weight, high energy consumption, and a high center of gravity—setting a benchmark for lightweight performance, low energy consumption, and effortless driving.

Core Highlights & Advantages

• Ultra-Lightweight (Class Benchmark)

  • Under-Chassis Battery + E-Axle Layout: Eliminates the cumbersome layout of central motors, driveshafts, and traditional rear axles, removing the need for heavy overhead battery frames.

  • Integrated Weight Reduction: The e-axle integrates the motor, reducer, and rear axle into a compact unit. Combined with a high-strength lightweight single-layer frame, curb weight is significantly reduced compared to traditional back-mounted battery-swapping or charging models, translating saved weight directly into higher payload capacity.

• Maximum Efficiency (Low Energy Consumption)

  • High Drivetrain Efficiency: Eliminating the driveshaft reduces mechanical energy losses, raising comprehensive drivetrain efficiency to over 95%.

  • Lower Drag & Center of Gravity: The under-chassis battery lowers the center of gravity, while streamlined cabin design reduces aerodynamic drag during cruising and port transit.

  • Smart Energy Recovery: Tailored for frequent start-stop port conditions, a multi-stage adjustable regenerative braking system lowers power consumption by 8%–12% compared to conventional electric setups.

• Enhanced Safety & Handling

  • Low Center of Gravity: Lowering the mass center minimizes body roll, boosting anti-rollover safety during high-speed coupling maneuvers or sharp turns in port lanes.

  • Unobstructed Rear View: Removing the back-mounted battery tower dramatically improves rearward visibility and makes connecting trailer lines safer and faster.

  • Smooth & Quiet Drive: Linear power delivery from the e-axle removes shifting jerkiness, while multi-point cabin suspension and noise isolation deliver passenger-car-like comfort.

• Worry-Free Range (400kWh Capacity)

  • Equipped with a 400kWh LFP battery pack supporting dual-gun high-power DC fast charging to minimize downtime.

  • Optimized for round-the-clock shift rotations in port shuttle operations without range anxiety.

Customer FAQ

• Q1: Why choose an “under-chassis 400kWh battery” over a traditional back-mounted tower?

  A: Back-mounted batteries suffer from high center of gravity, blocked rear visibility, and heavy support structures. Mounting the 400kWh battery under the chassis lowers the center of gravity for safer turning and coupling, restores rear visibility, and removes heavy mounting brackets to increase legal payload.

• Q2: What are the practical benefits of an electric drive axle over a central motor + driveshaft?

  A: E-axles represent the technological trend in heavy EV design. By cutting out the driveshaft and universal joints, the shorter drivetrain reduces energy loss (saving electricity) and creates a more compact chassis footprint to better accommodate under-body batteries.

• Q3: How long does the 400kWh battery last in port operations, and how fast does it charge?

  A: Thanks to low power consumption from the e-axle design, 400kWh comfortably covers a full day of high-intensity port shuttle duty. Dual-gun fast charging replenishes most of the battery capacity in 45–60 minutes during driver shift changes or break times.

• Q4: Why is this vehicle called the “lightweight benchmark of its class”?

  A:It achieves weight reduction without compromising structural integrity. Through a three-in-one approach—under-chassis battery optimization, integrated e-axles, and a lightweight high-strength steel frame—it reaches top-tier curb weight efficiency for 400kWh class heavy Trucks, maximizing legal freight capacity per trip.
