80ton Hydraulic Crawler Excavator
1.Powered by high-power heavy-duty engine and large-displacement hydraulic system, equipped with 5.2–5.5m³ rock bucket as standard. It leads the class in digging force and productivity, suitable for mines, large infrastructure, crushing and other high-intensity conditions with stable continuous operation.
2.Reinforced structure and high-strength wear-resistant materials for key parts greatly extend the service life of undercarriage and working equipment. Core components feature low failure rate and easy maintenance, saving fuel and cutting total owning & operating cost in long run.
3.Intelligent electronic control system optimizes engine-hydraulic matching. The cab is sealed, shock-absorbing, dust-proof and noise-reducing, with large display for monitoring and diagnostics. Panoramic view and full safety protection ensure easier operation and safer construction.
As the core main equipment for ultra-heavy-load scenarios such as large-scale mining, large-scale infrastructure projects, and open-pit stripping, the 80-ton class excavator focuses on the four core demands of "ultra-heavy load, high efficiency, long service life, and low operation and maintenance" compared with small and medium-tonnage models. Its core configuration adopts the golden combination of Cummins QSM11 heavy-load calibrated engine + Kawasaki large-displacement main pump + Toshiba high-pressure main valve, supplemented by a reinforced whole-machine structure and intelligent heavy-load control system. It not only has basic heavy-load capacity, but also achieves comprehensive upgrades in extreme working condition adaptation, energy saving and consumption reduction, and safety protection. The following is the detailed product details and supplementary advantages.
Cummins QSM11 Heavy-Load Calibrated Engine (Exclusive Adaptation for 80-ton Class)
Upgraded Heavy-Load Power: Specifically calibrated for the ultra-heavy-load needs of the 80-ton class, with a displacement of 10.8L, power increased to 380-420hp, and maximum torque exceeding 2200N·m. Compared with the 52-ton class adapted version, the power is increased by more than 20%, which can easily drive a 5.2-5.5m³ rock bucket to complete hard rock excavation and large block material loading and unloading. It maintains stable speed during full-load operation without power attenuation, adapting to the high-intensity continuous operation needs of mines.
Optimization for Extreme Working Conditions: Added low-temperature preheating function, which can start normally in extreme low-temperature environments of -30℃. At the same time, the cooling system is optimized to adapt to 45℃ high-temperature open-pit mine operations, avoiding engine overheating and shutdown; the air intake system is upgraded to four-stage filtration, with a dust filtration effect of 99.995%, which greatly reduces the wear of the engine caused by the high-dust environment of mines and extends the service life to more than 12,000 hours.
Balanced Heavy-Load and Energy Saving: Optimized the electronic control fuel injection system to achieve precise fuel injection adjustment according to the 80-ton class operation load fluctuation. It saves 5%-8% fuel under heavy-load conditions and reduces fuel consumption by more than 15% during light-load standby. Long-term continuous operation (6,000 hours per year) can save hundreds of thousands of yuan in fuel costs.
Kawasaki Large-Displacement Main Pump + Toshiba High-Pressure Main Valve (Exclusive Adaptation for 80-ton Class)
Upgraded Displacement and Pressure: The Kawasaki main pump is upgraded to a large-displacement variable dual pump, with a displacement 30% higher than that of the 52-ton class adapted version, and the maximum working pressure can reach 35MPa. It can quickly provide sufficient hydraulic power for the 80-ton class whole machine, increase the speed of excavation, rotation and walking actions by 25%, and shorten the single excavation cycle time to 18-20 seconds, greatly improving operation efficiency.
High-Pressure Sealing and Impact Resistance Enhancement: The Toshiba main valve is upgraded to a high-pressure model, adopting a reinforced sealing structure, which can withstand 35MPa high-pressure impact and avoid hydraulic leakage under ultra-heavy-load conditions; the valve core is made of aerospace-grade wear-resistant materials and undergoes special heat treatment, reducing the wear rate by 40%, and the hydraulic system failure rate is reduced to less than 1%, greatly reducing downtime for maintenance.
More Intelligent Synergistic Control: Added load-sensitive synergistic control function, realizing linkage adjustment of the engine, main pump and main valve, automatically distributing power according to the operation load, avoiding power waste, reducing hydraulic impact, extending the service life of the hydraulic system, and adapting to complex heavy-load conditions such as 80-ton class hard rock excavation and slope trimming.
