Engineered for Uncompromising Durability in Extreme Environments

Supported by a robust one-year warranty, the A6VM Hydraulic Motor for Liebherr Wheel Loader Drive applications is built to excel where others fail. Its design incorporates exceptional resistance to extreme pressure shocks, abrasive contaminants, and thermal stress. This is critical for machinery operating in environments ranging from dusty quarries to frozen mining sites. Specific models, such as those identified by the service part number 512214114, are constructed with hardened components and advanced sealing technologies to ensure longevity under continuous high load, minimizing unscheduled downtime for fleets.

Versatile Power Core for Diverse Heavy Machinery

The A6VM’s design integrity makes it a trusted component across multiple high-stakes industries:

Construction & Earthmoving: Beyond its primary role as a wheel drive motor for Liebherr (liebherr.com) loaders, it reliably powers track drives for excavators and swing systems for cranes. For example, a variant like 512253314 may be specified for demanding swing applications, offering smooth and controlled rotation.

Mining & Quarrying: In articulated dump trucks and stationary crushers, the motor’s ability to handle 350-450 bar pressure continuously is paramount. Its robust construction, akin to models referenced as 10023569, ensures operation in high-particulate environments common to mining operations.

Agricultural Machinery: For large, high-horsepower equipment such as forage harvesters from CLAAS (claas.com), the precise speed and torque control of an A6VM motor (e.g., part 10290082) are essential for efficient crop processing.

Material Handling & Forestry: These motors drive heavy-duty forklifts, port equipment, and the swing functions of forestry harvesters. Their compatibility with various gearboxes, indicated by codes like 512414814 and 11114807, makes them a flexible solution for integrated drive systems.

FAQ

Q1: What makes the A6VM motor specifically suitable for the drive system of a Liebherr wheel loader?
A1: Its high power density and ability to deliver high torque across a wide speed range match the dynamic “load-and-carry” cycles of a loader. The motor provides the instant torque needed for digging into a pile and the controlled speed for smooth travel, ensuring both power and efficiency.

Q2: How does the motor handle the severe pressure spikes generated when a loader bucket impacts solid material?
A2: The A6VM is designed with a robust internal structure and pressure-dampening characteristics to absorb and withstand severe hydraulic shock loads. This exceptional anti-pressure shock capability protects both the motor and the wider hydraulic system, a feature critical for components like 5716391 used in heavy-impact applications.

Q3: Is the A6VM motor suitable for applications requiring frequent starts and stops under full load?
A3: Yes. The A6VM motor’s high starting torque and efficient design allow for reliable performance in applications with cyclical duty patterns, such as in compactors or certain conveyor drives, without overheating or loss of performance.

Q4: We require a replacement drive motor for our loader, corresponding to Liebherr part number 512414814. Can you supply it?
A4: Absolutely. We specialize in providing high-fidelity hydraulic solutions for global equipment brands.
