- Direct Drop-In Replacement — engineered to match the original mounting points and geometry of the BW 100 and BW 120 series, this frame installs without modification or fabrication
- Broad Tandem Roller Coverage — fits the BW 100 AC-3, BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW120AD 3, and BW120 AD-3 tandem rollers, making it a practical stocking part for mixed fleets
- Restores Machine Stability — a compromised supporting frame can affect component alignment and overall machine rigidity; replacing it with a correct OEM part restores the structural foundation the roller depends on
- Verified by Part Number — ordering by Bomag part number 78003215 eliminates guesswork and ensures full compatibility with the machines listed above
The supporting frame is a primary structural component that anchors and aligns key assemblies within the tandem roller's chassis. It bears operational loads during compaction passes and maintains the positional relationship between drivetrain, drum, and operator-facing systems. When a supporting frame becomes cracked, deformed, or worn, it can cause misalignment of connected components, vibration irregularities, and accelerated wear on surrounding parts — making timely replacement essential to keeping the machine performing as intended.
