Performance Advantages

The HY870H-S mining excavator integrates optimized power and hydraulic matching to boost digging efficiency while cutting fuel cost. Its 420kN bucket digging force and 365kN arm digging force handle hard rock excavation effortlessly. Dual swing mechanism raises swing torque for fast material loading cycles. Reinforced structural parts reduce maintenance frequency, while multi-type buckets expand applicable scenarios. The wide-view cab and intelligent monitoring system ease operator fatigue and lower operation error rate. Low ground pressure and 35° climbing capacity ensure stable driving on rugged mine terrains, maximizing daily output for mining projects.

Hiyo HY870H-S large hydraulic excavator is a top-tier mining machinery built for open-pit mining and heavy stone works. Powered by reliable Isuzu 6WG1 engine with 382kW power output, it generates huge torque to break and load hard rock without power lag. Kawasaki full electronic hydraulic system adopts heavy-load P-Q power control, balancing high productivity and low fuel consumption. The 5.4m³ standard rock bucket greatly increases loading volume per cycle, with four interchangeable buckets for earth, crushing and heavy mining tasks. Reinforced high-strength steel working attachments reach 20,000-hour service life, cutting downtime and maintenance expense. The Stage IV emission aftertreatment system meets global strict environmental rules. Equipped with a smart C12 cab and 10-inch control screen, operators can monitor machine status, detect faults and call service with one click. With strong digging force, stable traveling and excellent climbing capacity, this 78.6-ton excavator becomes a cost-effective core equipment for mine and large earthwork projects worldwide.

For mining operators pursuing comfort and intelligence, Hiyo HY870H-S Stage IV excavator delivers full-round upgrades in cab and digital control. Its newly upgraded C12 cab expands internal space by 25mm and enlarges glass area by 10%, offering wider vision for safe mine operation. Optimized air duct raises cooling efficiency by 10%, with larger condenser supporting easy on-board cleaning. The built-in 10-inch smart touch screen integrates Bluetooth, GPS, automatic startup, real-time fault alarm and one-click service request, realizing full intelligent construction management. Under the hood, Isuzu engine and Kawasaki hydraulic system cooperate to maintain smooth compound movements while lowering fuel waste. The whole machine adopts SCR+DOC+DPF emission technology for cleaner exhaust. Reinforced bucket arms and customizable buckets adapt to various harsh mine conditions. With low ground pressure and 35-degree gradeability, the machine keeps stable on uneven mine ground. It combines intelligent operation, long service life and low running cost, ideal for long-shift heavy mining jobs.
