Application of orbital hydraulic motors in mining machinery

Why Mining Machinery is Instantly Recognizable at Industrial Exhibitions

When visiting an engineering or mining machinery exhibition, even non-specialists can immediately identify mining equipment. But what makes these machines visually distinctive?

 

 

1. Compact Design
Underground mining operations demand space efficiency. Equipment must maintain high power output while minimizing footprint.

 

2. Hydraulic Dominance
Electrically-driven components are avoided due to explosive risks in mining environments. This is where orbital hydraulic motors excel-delivering exceptional power density in compact packages.

 

 

 

1. Tunnel Boring Machines (TBMs)

Functions: Integrated rock cutting, loading, and transportation

Motor Applications:

Cutting arm lifting/rotation

Crawler propulsion (for small/medium TBMs)

 

2. Anchor Drilling Rigs

Critical Process: Roof/sidewall drilling and anchor installation

Motor Roles:

Drill arm positioning

Rod rotation

Propulsion system

Platform rotation

 

3. Rock Drilling Rigs

Key Mechanisms:

Drill arm positioning

Propeller systems

Chassis adjustments

 

4. Mining Transport Vehicles

Primary Use: Steering mechanisms

 

5. Additional Applications

Continuous miners

Mine shuttle cars

Mobile crushers

 

 

Safety: No spark risk in explosive atmospheres

Power Density: 30-50% more torque than electric equivalents at similar sizes (ISO 4401 standards)

Adaptability: Customizable for extreme conditions (-40°C to 120°C operational range)
