Our high-performance small amphibious excavators combine compact agility with heavy-duty buoyancy pontoons, engineered specifically for mine tailing management, marshland infrastructure, and river channel desilting under rigorous northern climatic conditions.
Erdenet, located in northern Mongolia's Orkhon Province, represents one of the most concentrated mining and metallurgical hubs in Central Asia. Centered around the massive open-pit copper-molybdenum deposits operated by the Erdenet Mining Corporation (EMC), the regional geography presents a unique mix of sub-arctic wetland ecosystems, permafrost thaw zones, low-elevation river basins (such as the Khangal River catchment), and expansive industrial tailings impoundments. Standard crawler excavators operating in these terrains face severe operational limitations: high ground pressure ($>35\text{ kPa}$) risks catastrophic machine sinks in un-consolidated slurry, while conventional flotation devices lack the structural rigidity to navigate frozen mud crusts.
As global mining standards shift toward strict Environmental, Social, and Governance (ESG) compliance, the management of mine tailings ponds and local hydrologic preservation has become paramount for operators serving the Erdenet sector. Small amphibious excavators (ranging from 1-ton micro units to 15-ton specialized pontoon excavators) have emerged as essential capital equipment. These machines provide an optimal balance: low displacement ground bearing pressure ($8.5\text{ to }14.5\text{ kPa}$), modular transportability over mountainous logistics routes, and multi-functional hydraulic power capable of driving slurry pumps, cutter heads, and wide-swath desilting buckets.
Continuous desilting and water clarification of tailings impoundments demand machinery that floats safely while maintaining excavation break-out forces in dense mineral mud.
Operating in Erdenet's extreme continental climate requires arctic-grade hydraulic seals, cold-start glow systems, and anti-cracking high-tensile steel pontoons.
Ecological restoration and flood containment along the Khangal River require precise aquatic excavation to prevent downstream heavy metal migration.
Shandong BTEra Excavator Co., Ltd. builds specialized amphibious excavators utilizing multi-chamber pontoon designs and high-torque hydraulic motors. Unlike aftermarket retrofits, our factory-integrated pontoon undercarriages are custom-engineered for maximum stability, hydrodynamic efficiency, and zero operational downtime.

Each pontoon hull is divided into multiple independent water-tight bulkheads. In the rare event of an exterior hull breach caused by sharp mine tailings or underwater debris, the remaining sealed compartments retain over 85% of total flotation capability, preventing machinery capsize and ensuring safe recovery.
To survive Mongolian winter operations in Orkhon Province, our machines utilize synthetic low-viscosity hydraulic oils combined with high-pressure thermal oil heaters. Hydraulic lines are insulated and fitted with arctic-rated synthetic rubber seals to prevent oil leaks at temperatures down to -40°C.
Deploying amphibious heavy machinery in Erdenet requires specialized operational configurations designed around local geological and hydrological challenges. Below are the primary application domains where BTEra amphibious excavators deliver clear productivity advantages:
Erdenet’s massive metallurgical operations generate vast volumes of fine tailings slurry. Over time, sediment buildup decreases reservoir storage capacities. Standard land excavators cannot traverse the soft, unstable tailings crust. BTEra amphibious excavators fitted with continuous hydraulic slurry pumps skim directly across liquid mud, restoring storage volume without costly land reclamation structures.
Spring thaws in northern Mongolia cause rapid riverbank runoff. Dredging river channels and reinforcing embankments along the Khangal River demands machinery capable of operating mid-stream. Our track-pontoon units maneuver easily through deep silt, clearing sandbars and heavy debris to preserve natural aquatic habitats.
Installing power lines, road culverts, and pipeline crossings across the marshy soil zones surrounding Erdenet requires low-ground-pressure equipment. Operating at under 11.5 kPa, BTEra machines prevent soil trenching and ground compaction, complying with Mongolian Ministry of Environment guidelines.
Urban sprawl and industrial expansion in Erdenet require ongoing maintenance of drainage ditches and sediment traps. Small 1-ton to 3-ton amphibious excavators access narrow waterways and urban culverts where traditional heavy equipment cannot fit.
