  • Patent number: 5526713
    Abstract: The present invention provides an improved axially pivotable dolly crank handle for adjusting a conventional dolly stand post on a conventional tractor trailer, particularly when the tractor trailer is parked in very close proximity to another tractor trailer or other obstruction which restricts rotational movement of a conventional dolly crank handle. The present invention has spring-tensioned cooperating male and female members which interlock together in a plurality of orientations about an axial core. Aligning and engaging the male member with the female member locks the present invention in one of the plurality of orientations, and the spring retains the present invention in this locked position. The present invention is then used to rotate the conventional dolly stand post on the conventional tractor tailor in a manner well-known in the art.
