68-ton Large Hydraulic Crawler Excavator: Redefining the Standard for Large-Scale Engineering Operations

As a strategic product in the field of heavy earthmoving machinery, the 68-ton Large Hydraulic Crawler Excavator represents the pinnacle of modern engineering technology. Its design philosophy and performance parameters are all directed toward one core objective: achieving sustained high-efficiency operation under extreme working conditions. This equipment not only meets the rigid demands of large-scale mining and infrastructure construction but also redefines the productivity and durability standards for machinery in this tonnage class through the application of a series of innovative technologies.

Synergistic Innovation in Power and Hydraulic Systems

The machine is equipped with a high-power-density electronically controlled diesel engine that complies with Tier 4 Final / China IV emission standards. Its rated power reaches 336 kW, with maximum torque exceeding 1,800 N·m. This power core is perfectly matched with a closed-center, load-sensing hydraulic system. The main hydraulic pump utilizes dual-pump merging technology, capable of delivering a hydraulic flow output of up to 2 × 450 L/min. Combined with electro-proportional control valves, it achieves precise fine-tuning of movements and smooth compound actions. The bucket's maximum breakout force reaches 380 kN, and the stick's maximum digging force reaches 290 kN, ensuring efficient excavation and loading capabilities even when dealing with hard rock.

Structural Durability and Operational Stability Design

To cope with immense working loads and impacts, the key structural components of the machine have been comprehensively reinforced. The boom and stick feature box-section design and are manufactured using HG785 high-strength steel, with additional reinforcement plate thickness in stress concentration areas. The track frame employs an X-shaped integrated welded structure, optimized through Finite Element Analysis (FEA), resulting in a approximately 25% increase in torsional stiffness. The standard track shoe width is 600 mm, and the ground pressure is reduced to 120 kPa, providing exceptional ground adaptability and stability, allowing safe operation even on soft dump sites.

Intelligent Management and Maintenance Economics

The integrated intelligent control system is a standout feature of the equipment. It comes with a 10-inch color touchscreen that displays real-time operating parameters and includes functions such as work mode memory, fuel management, and fault self-diagnostics. Furthermore, the CAN bus-based telematics management system allows fleet managers to remotely monitor the equipment's location, working hours, fuel consumption, and maintenance cycles, enabling predictive maintenance.

With centrally located lubrication points, daily lubrication time is reduced by approximately 40%. The replacement intervals for fuel filters and pilot filters are extended to 1,000 hours, effectively reducing the total lifecycle operating costs. Calculations show that in typical mining stripping operations, this equipment can achieve an average annual effective working time of over 6,000 hours, with an availability rate steadily above 95%, providing a solid guarantee for customers' return on investment.
