The Wacker Neuson Arm Lock is a genuine OEM component designed for the RD11AEC, RD11V, and RD11A hydrostatic double drum vibratory rollers. As a direct factory replacement, this part is manufactured to the exact specifications Wacker Neuson requires for proper fit and function on these tandem roller models. Sourcing the correct OEM Arm Lock ensures the locking mechanism operates exactly as intended, keeping the machine's articulation system secure during operation and transport.
Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to meet the precise dimensional and material tolerances required for positive engagement in the articulated frame locking system.
- Direct Bolt-On Replacement — Designed to install in the same position and mounting points as the original, with no reworking of the surrounding hardware required.
- Confirmed Fitment for RD11 Series — Compatible with the RD11AEC, RD11V, and RD11A hydrostatic double drum vibratory rollers, covering the key variants in the RD11 tandem roller family.
- Secures Articulation for Safe Handling — A functioning Arm Lock is critical when transporting or servicing the roller; a worn or missing lock allows unintended frame movement, creating a serious safety hazard for the operator and ground crew.
- Protects Surrounding Components — Proper locking prevents stress on the hydraulic lines and pivot joints that run through the articulation zone, extending the service life of adjacent components.
The Arm Lock on an articulated tandem roller is the mechanical latch that fixes the front and rear frame sections together, preventing the machine from swinging or pivoting at the articulation joint when it is not in use, during loading, or while being serviced. Without a properly functioning Arm Lock, the two drum sections can move independently under their own weight, which makes the machine unstable and unsafe to handle off the work surface. A damaged or missing Arm Lock should be replaced before the roller is transported or placed back into service.
