BDASS Full-Hydraulic Steering Unit
Proportional power steering with no mechanical shaft between wheel and axle — the complete steer module for wheel loaders, forklifts, and motor graders operating in confined, heavy-duty environments.
THOTH full-hydraulic steering units convert steering wheel input into metered hydraulic flow to the steering cylinder. A rotary valve directs oil in proportion to the angular rotation of the wheel — power-assisted, proportional steering without any mechanical linkage.
The BDASS configuration serves as a complete drive-and-steer module in industrial and construction vehicles, providing instant, smooth response to operator input and stable flow supply even under high-load operation.
Active OEM supply references include tractors, wheel loaders, forklifts, and wheeled excavators. Direct-fit replacement for Eaton Char-Lynn, Danfoss OSPB/OSPC/OSPF, and White series in many applications — contact THOTH for cross-reference data.
