2. Key Product Features | High Efficiency, Low Fuel Consumption & Extreme Durability
2.1 Cummins QSM11 Original Powerful Engine
Fitted with Cummins QSM11 inline-six turbocharged intercooled diesel engine with rated output of 280kW. Abundant power reserve and instant explosive torque eliminate power attenuation when working on high-altitude areas or hard rocky soil. Ideal for full-bucket digging and frequent heavy-load relocation.
2.2 Energy-Saving Optimized Hydraulic System
Adopts premium matched combination of variable displacement piston pump plus gear pump, maximum system working pressure reaches 34.3MPa. The hydraulic system automatically adjusts oil flow based on real-time working load, cutting overall fuel consumption by 20%~30% vs traditional fixed-displacement hydraulic excavators and slashing annual operational expenditure for end users.
2.3 Mining-Grade Reinforced Body Structure
Boom, arm, revolving platform and entire undercarriage are constructed with high-strength wear-resistant steel customized for harsh mining environments. Supported by 290KN strong arm digging force and optimized force-bearing design, the SH500-9 heavy excavator resists continuous heavy impact and greatly cuts daily maintenance frequency and spare part cost.
2.4 Ergonomic Comfort Operator Cabin
Spacious cabin with full-view panoramic glass and floating shock-absorbing suspension seat paired with intelligent electronic control joysticks. Operators stay less fatigued during long-shift continuous work, improving overall machine working efficiency by over 15%.
3. Target Working Solutions for Mining & Construction Pain Points
Most large mining and deep foundation projects suffer from insufficient digging power, rapid bucket tooth abrasion and excessive fuel cost on conventional excavators.
SH500-9 solves these industry drawbacks perfectly with 290KN strong arm breakout force and large 2.8m³ capacity bucket: faster rock stripping and bulk truck loading to boost site productivity; well-matched power train balances high output with low fuel burn and maximizes customers’ project profit margin.
