In countries like Democratic Republic of Congo (DRC), Mali and Ghana, placer mining remains a popular and lucrative form of mineral extraction. By recovering valuable resources from riverbeds, sand or gravel, placer mining offers lower entry costs compared to deep-level or hard-rock mining. This accessibility has made it a cornerstone of artisanal and industrial mining across Africa.

A vital part of modern placer mining is the excavator. These machines are indispensable for removing overburden, digging gold-bearing gravel and feeding material into wash plants or sluice boxes.

When it comes to excavation, LiuGong has built a reputation for durability, efficiency and versatility. Among its lineup, the 936E (Placer Gold Version) Excavator stands out as a reliable workhorse for placer operations.

The role of the excavator in placer mining

Excavators are the backbone of placer mining. They dig up sediment, strip away vegetation and non-gold-bearing layers, and load pay dirt into processing equipment. Without them, large-scale placer operations would be far less efficient.

The LiuGong 936E  (Placer Gold Version) is powered by a Cummins 6LTAA8.9-C325  engine, delivering a rated power of 323 hp (241 kW) at 2 000 rpm. This gives it the muscle to tackle tough overburden and expose valuable deposits.

With a bucket capacity of 1,9 m³, a maximum digging depth of 7 340 mm and a travel speed of 5,3 km/h, the 936E ensures fast cycle times and continuous productivity throughout the day.

Power meets precision

What makes the 936E (Placer Gold Version) exceptional is its balance of raw power and precise control. In heavy machinery, the phrase power meets precision signals innovation, and LiuGong has embodied this concept in the 936E (Placer Gold Version).

Key specifications include:

  • Operating weight: 37 800 kg
  • Swing speed: 9,2 rpm
  • Drawbar pull: 348 kN
  • Bucket digging force: 252 kN
  • Arm digging force: 185 kN

The machine’s negative flow hydraulic system is a standout feature. By reducing unnecessary oil flow, it lowers engine load, saves fuel and provides faster response times. Operators benefit from smoother, more accurate movements, while cycle times improve significantly. Additionally, less wasted energy means cooler hydraulic oil, reduced wear and tear and consistent hydraulic power across different operations.

Built to work

The LiuGong 936E (Placer Gold Version) is engineered for durability and reliability. Its ROPS-certified cab ensures operator safety, while its robust design allows it to handle the toughest jobs with ease. Fuel efficiency, versatility and the ability to fit different buckets or attachments make it ideal for placer mining tasks such as dredging, trenching or handling oversized rocks.

In placer mining, where efficiency and adaptability are critical, the 936E delivers. It combines the strength to move massive volumes of material with the precision needed to maximise recovery. For miners in Africa and beyond, it represents a machine built not just to work, but to excel.
