The Wacker Neuson Arm Lock is a genuine OEM component designed for the RT560, RT820, and RT820HT Vibratory Trench Rollers. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. It is confirmed to fit multiple machine configurations across the RT560 and RT820 series, making it a straightforward like-for-like replacement. If your trench roller is showing signs of arm movement or instability, replacing the Arm Lock promptly keeps the machine operating as designed.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's exact tolerances, ensuring the locking mechanism engages and retains with the same holding force as the original part.
- Direct-Fit Replacement — Designed to install in the same position as the original Arm Lock, with no reworking of mounting points or hardware needed.
- Broad RT-Series Compatibility — Fits RT560 and RT820 model families, including RT820HT configurations, across multiple machine serial number ranges.
- Structural Integrity Restored — A worn or failed Arm Lock can allow unintended articulation or movement; replacing it restores correct arm positioning and control during operation.
- Operational Safety — On remote-controlled trench rollers, a properly functioning Arm Lock is critical to maintaining predictable machine movement and operator control from a safe standoff distance.
The Arm Lock on a Wacker Neuson RT-series trench roller is a mechanical retention component that secures the articulated arm assembly in its intended position during operation or transport. It prevents uncontrolled movement of the arm under load, which is especially important on remote-controlled machines working in confined trench environments where precise machine behavior is essential. When the Arm Lock wears or fails, the arm can shift unexpectedly, compromising both machine control and operator safety.
