en.Wedoany.com Reported - The Shantui SE1200HK large excavator undertook hard rock breaking and stripping tasks at a large mine in East China. Relying on its power system, bucket and breaker configuration, and job site adaptability, it successfully passed the high-intensity field test.
The rock mass in this mine is hard, with loose stone on the surface and dense rock underneath, placing high demands on equipment power output, structural strength, and operational flexibility. The customer needed a versatile machine capable of both efficiently stripping the surface layer and breaking hard rock. The Shantui SE1200HK met these high requirements with its reinforced working devices and mining-specific undercarriage.
The SE1200HK is equipped with a high-power engine, delivering torque and power superior to competitors in its class. Coupled with a large-displacement main pump and a fully electronically controlled hydraulic system, it offers rapid response and smooth control. For different rock layers, the equipment can flexibly switch between a ripper arm and a large hydraulic breaker: the ripper arm is used for loose surface rock, achieving large single-pass breaking volume and high efficiency; for the hard rock underneath, it switches to a high-efficiency, heavy-duty breaker. The entire machine adopts Shantui's reinforced mining-grade track system, and the extended track gauge design enhances load-bearing capacity, improving durability and stability under harsh conditions.
In actual operation, the SE1200HK demonstrated high attendance and production efficiency, with a stable hourly breaking output at the kiloton level and fuel consumption performance superior to similar products. Operators reported coordinated movements and good controllability. The customer evaluated that the equipment performed excellently in both ripper arm and breaker modes, delivering large output volume, low fuel consumption, and stable operation, fully meeting the project timeline requirements.
The dual independent temperature-controlled cooling system ensures the equipment always operates at the optimal working temperature. The successful operation of the SE1200HK validates the reliable strength of domestically produced large mining equipment under hard rock conditions, providing valuable experience for future market promotion and product iteration.
