RW-1420/1630 UC

DMF RAILGEAR RW-1420/1630 UC

DMF offers three types of mid-mount railgear for those applications which require a shorter rail-wheelbase than our standard railgear provide for a given chassis. Generally, this is necessary if a large vehicle is to be used on track having tight curvature. DMF Mid-Mount railgear are equipped with a rubber compression suspension system and both rail and highway mode safety pin-offs. All DMF Mid-Mount railgear is used with a corresponding standard rear unit. There are many additional considerations (frame location, stability, rail curvature etc.) in using mid-mount gear so please contact DMF for assistance in specifying and ordering this type of railgear.
