Application Scenarios
EPC contractors performing deep foundation excavation.
Mining operators conducting stripping, loading, and haul road construction.
Municipal engineering for pipelines and large infrastructure foundations.
Aggregate quarrying including rock breaking and hydraulic hammer operations.
Civil contractors engaged in bulk earthworks and slope stabilization.
Core Pain Points & Engineering Solutions
High fuel consumption → adopt electronically controlled fuel mapping and large-torque low-RPM engines.
Component wear in heavy-duty environments → use reinforced bushings, high-strength steel, upgraded seals.
Hydraulic overheating → multi-layer radiator and independent cooling fan systems.
Downtime due to maintenance difficulty → modular engine bay and grouped service ports.
Risk Warnings & Mitigation
Avoid overloading attachments beyond rated bucket capacity.
Conduct daily hydraulic oil inspections to prevent pump damage.
Use certified operators to prevent boom stress failures.
Strictly follow 500-hour service cycles to maintain warranty validity.
Procurement Selection Guide
Define project requirements: volume, soil type, operation hours/day.
Confirm engine emission standard for target market (Tier 3/4F).
Evaluate hydraulic pump flow and cycle time efficiency.
Check undercarriage reinforcement, rollers, and track shoe grade.
Verify attachment compatibility: buckets, hammers, grapples.
Assess supplier production capacity and after-sales support.
Request field test data and durability testing reports.
Engineering Case Study
A Middle Eastern EPC contractor deployed twelve 36 Ton Heavy-Duty Excavators for a desert highway project. Machines operated 14 hours/day under 48°C ambient temperature. The optimized cooling system reduced hydraulic overheating by 37%, and reinforced booms extended service life by 22%, resulting in measurable downtime reduction and improved excavation productivity.
