A2FE107/61W-VZL171-S: Unyielding Traction for Tunnel Boring Operations

In the subterranean environments of tunneling and mining, equipment faces relentless mechanical stress. The Rexroth A2FE107/61W-VZL171-S hydraulic motor is engineered specifically to meet these grueling demands. As a high-performance axial piston quantitative motor, it serves as the primary traction drive for roadheaders and tunnel boring machines, delivering robust power transmission where failure is not an option.

Engineered for Extreme Duty

The A2FE series is designed for both open and closed hydrostatic transmission circuits, making it highly versatile for mobile and industrial machinery. The A2FE107/61W-VZL171-S model features a compact structural footprint while maintaining an exceptional power-to-weight ratio. Its internal architecture utilizes integral tapered pistons equipped with sealing rings, which significantly reduces friction and enhances operational longevity under continuous heavy loads.

Dynamic Performance Characteristics

Tunneling operations require consistent torque and adaptable speed control. This motor achieves this through its fundamental hydraulic principles:

• Proportional Speed Control: Output rotational speed is directly proportional to input flow and inversely proportional to displacement, allowing operators to adjust travel speeds seamlessly based on geological resistance.

• Load-Responsive Torque: Drive torque naturally increases in response to higher pressure drops across the motor's high and low-pressure sides. This ensures that the roadheader maintains its pushing force when encountering harder rock formations.

• High-Pressure Endurance: Rated for a maximum working pressure of 30 MPa, the unit provides the necessary muscle to propel heavy machinery forward without cavitation or stalling.

Optimized for Roadheader Mobility

As a dedicated walking motor for tunneling equipment, the A2FE107/61W-VZL171-S excels in translating hydraulic energy into reliable mechanical movement. Whether navigating uneven tunnel floors or executing precise positioning maneuvers during excavation, the motor delivers smooth acceleration and stable holding capabilities. Its economic design philosophy ensures that heavy-duty performance does not come at the cost of excessive maintenance or fuel consumption.

Supply Chain Reliability

Sourced from established hydraulic distribution networks, the A2FE107/61W-VZL171-S is readily available to minimize equipment downtime. With fast dispatch capabilities and substantial inventory reserves, operators can secure replacement units swiftly to maintain project schedules. The motor represents a critical intersection of German engineering standards and practical field application, ensuring that tunneling projects progress safely and efficiently beneath the earth's surface.
