Particulars Liugong 975E HD Liebherr R 978 SME Litronic
Overview Summary

The Liebherr R 978 SME Litronic and Liugong 975E HD are both powerful, extra-large excavators designed for mining and heavy-duty engineering tasks. The Liebherr model boasts a strong hydraulic system and operator amenities, while the Liugong offers a higher engine power and larger bucket capacity, enhancing its earthmoving capabilities.

Liebherr R 978 SME Litronic

Pros:
  • High rated engine power at 449 HP supporting heavy-duty operations.
  • Larger fuel tank (1140 L) provides extended operation time.
  • Dual Liebherr variable displacement swashplate pumps offer robust hydraulic performance.
  • Standard AC Cabin and GPS enhance operator comfort and efficiency.
  • Impressive arm and bucket digging forces (357 kN and 392 kN respectively) for tough excavating tasks.
Cons:
  • Slightly lower maximum travel speed (3.5 Km/h).
  • Engine displacement is higher (16.16 L), which can imply higher fuel consumption.
  • No information on gradeability to evaluate its performance on slopes.

Liugong 975E HD

Pros:
  • Higher engine power of 524 HP for increased performance.
  • Features a larger bucket capacity of 5.6 m³, suitable for substantial earthmoving tasks.
  • Gradeability of 70% (35°) showcases notable climbing capabilities.
  • Offers higher maximum travel speed (4.0 Km/h), improving site mobility.
  • Equipped with a high torque axial piston motor for the swing function, ensuring fast maneuvering.
Cons:
  • Smaller fuel tank capacity (1100 L) compared to Liebherr, which may affect runtimes.
  • GPS is not mentioned as a standard feature, potentially impacting navigational efficiency.
  • No information provided on ground bearing pressure to assess suitability for soft ground conditions.

Pros:
Cons:

Closing Recommendation

When choosing between the two, consider the specific requirements of the job at hand. The Liebherr R 978 SME Litronic may be more suitable for projects that demand consistent hydraulic performance and enhanced operator features. In contrast, the Liugong 975E HD should be the choice for tasks requiring higher engine power and larger excavation volumes. Assessing the usability features such as the GPS and gradeability alongside fuel efficiency and maintenance costs will provide a well-rounded decision.
