Shantui’s high-tonnage excavator lineup—specifically the SE350, SE380, and SE470—is engineered for heavy-duty applications like large-scale earthmoving, quarrying, and mining. True to your request, these models are typically paired with Cummins engines to provide the high torque and reliability required for intensive duty cycles.

Here is a breakdown of the technical specifications and key features for each model.

Shantui SE350 Excavator

The SE350 is a 35-ton class machine known as the "High-Efficiency King." It is designed to balance power with fuel economy, making it ideal for road construction and general excavation.

  • Engine: Cummins 6LTAA8.9-C325 (Rated Power: 241 kW / 323 hp).

  • Operating Weight: 34,500 – 35,200 kg.

  • Bucket Capacity: 1.6 – 2.2 m³.

  • Key Feature: Features a 37T slewing bearing for enhanced load capacity and a reinforced boom designed for durability in rocky terrain.

Shantui SE380LC Excavator

Stepping up to the 38-ton class, the SE380LC provides a more robust chassis and higher digging forces. It is frequently used in mining and heavy infrastructure projects where deep digging and high breakout force are essential.

  • Engine: Cummins QSL9 (Rated Power: 241 kW).

  • Operating Weight: ~38,000 kg.

  • Bucket Capacity: 1.8 – 2.5 m³.

  • Key Feature: Equipped with imported hydraulic components (often Kawasaki or Linde) and a three-stage engine hood that opens wide for easy maintenance access.

Shantui SE470LC Excavator

As one of Shantui's largest standard models, the SE470LC is a specialized mining excavator. It is built with a heavy-duty undercarriage and a reinforced bucket to handle the most abrasive materials.

  • Engine: Cummins QSM11 (Rated Power: 250 kW / 335 hp).

  • Operating Weight: 46,800 kg.

  • Bucket Capacity: 2.1 – 2.5 m³.

  • Key Feature: Utilizes a double-pump hydraulic system that delivers massive digging forces (288 kN bucket digging force) and features high-pressure common rail technology for better fuel performance under heavy load.

Upgraded Features & Design

Across all three models, Shantui has introduced several intelligent upgrades:

  • Cabin Comfort: Air-suspended seats and 10.1-inch smart touch screens are standard, providing a more automotive-like experience for operators.

  • Hydraulics: Precision control through Linde or Kawasaki hydraulic systems reduces back pressure and optimizes cycle times.

  • Chassis: The one track" system is reinforced for mining-grade reliability, which pairs perfectly with the higher horsepower of the Cummins units.
