Mining Giant | Shantui Large Excavator Strikes with Unmatched Toughness

Recently, at a large‑scale mine in East China, the Shantui SE1200HK large excavator has been continuously undertaking hard rock breaking and stripping tasks with an efficiency of over 1,000 tons per hour. As a 100‑ton‑class mining giant meticulously developed by Shantui, the SE1200HK has passed rigorous field tests with its robust powertrain, oversized bucket and breaker hammer configuration, and superior working‑condition adaptability. It stands as another landmark product of domestic large‑scale mining equipment.

The mine features hard rock formations: loose surface rock and compact bedrock underneath, which impose stringent requirements on excavators regarding power output, structural strength and operational flexibility. Faced with tight construction schedules, the client urgently needed an all‑round machine that can efficiently strip surface rock and break hard bedrock effortlessly. Tailor‑made for this demand, the Shantui SE1200HK delivers powerful hard‑rock breaking capacity with reinforced working attachments and mining‑specific undercarriage.

Powered by a high‑output engine, the SE1200HK achieves 30% higher torque and power than peer competitors. Combined with the industry‑largest 300 cc main pump and fully electronic hydraulic system, it features quick response and smooth operation, providing massive power for heavy‑duty breaking tasks. It can flexibly switch between the "Super Arm" and heavy‑duty breaker hammer for different rock layers: the 33‑ton Super Arm is used for loose surface rock with high single‑pass breaking volume and efficiency; the high‑efficiency heavy‑duty breaker hammer, paired with boom and arm, easily handles ultra‑hard bedrock. The machine adopts Shantui’s reinforced mining undercarriage. Its extended variable‑track design boosts load‑bearing capacity by 25%, greatly improving durability and stability under harsh working conditions.

In practical operation, the SE1200HK achieves ultra‑high availability and productivity, with a stable hourly breaking output of over 1,000 tons and better fuel efficiency than comparable products. Operators comment: “The machine has coordinated movements, easy control and high working efficiency.” Clients note: “This excavator performs excellently in both Super Arm and breaker hammer modes, with high output, low fuel consumption and stable operation, fully meeting our schedule requirements.” Its stable performance and remarkable productivity bring considerable economic benefits to mines.

As a key application case of Shantui’s large‑tonnage excavators in Zhejiang market, the successful operation of the SE1200HK not only verifies the reliable performance of domestic large‑scale mining equipment under hard‑rock conditions, but also offers valuable experience for subsequent market promotion and product upgrading. The dual independent temperature‑controlled cooling system keeps the machine operating at optimal temperature, further enhancing adaptability to complex working conditions.

From field validation to benchmark establishment, Shantui keeps expanding its large excavator product portfolio with heavy‑duty mining machines represented by the SE1200HK. Moving forward, Shantui will continue to focus on mining customers’ demands, providing more efficient, intelligent and reliable equipment as well as full‑life‑cycle services. It helps global mining clients reduce costs and improve efficiency, jointly creating a brilliant new chapter for domestic mining machinery.
