The Bomag 05561244 Total Automatic Interlock is a genuine OEM component designed for Bomag BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 120 AD-4, BW 125 AD-4, and BW 125 AC-4 tandem rollers. As a direct Bomag OEM part, it is produced to the exact specification of the original, ensuring proper integration with the machine's control systems. This interlock is a critical safety and operational component — sourcing it as a genuine OEM replacement is the surest way to maintain correct machine behavior across the full BW 100, BW 120, and BW 125 tandem roller lineup.
Key Features
- Genuine OEM Specification — manufactured by Bomag to the precise tolerances and switching characteristics required for correct interlock operation, not an approximation of the original
- Direct OEM Replacement — engineered to install in place of the original unit with no adaptation, using the same mounting points and electrical connections as the factory component
- Broad Tandem Roller Coverage — fits BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, and BW 125 AC-4 tandem rollers, covering key machines across the BW 100 and BW 125 series
- Operational Integrity — a properly functioning automatic interlock keeps the machine's drive and control sequences in their correct order; a failed or degraded unit can cause erratic or unsafe machine response
- Safety-Critical Component — interlock systems are designed to prevent unintended machine movement or engagement; using a genuine OEM replacement ensures the interlock performs exactly as Bomag's engineers intended
The total automatic interlock is a safety and sequencing device that governs the relationship between operator inputs and machine functions — preventing the roller from engaging drives or mechanisms outside of the correct operating sequence. On tandem rollers like the BW 100 and BW 120 series, this component plays a direct role in ensuring the machine responds predictably and safely to operator commands. When the interlock wears out or fails, operators may experience unexpected machine behavior, loss of control interlocking, or the machine may fail to engage altogether — making prompt replacement with part number 05561244 essential to safe, compliant operation.
