ABSTRACT:
A crane design which permits limited rotation in the plane of loading of the upperworks of a pedestal crane independently of the central support thereof, and independently of the thrust and radial bearings about an extension of such central support. Means for centering the vertical loading vector and horizontal overturning moments by restricting the possible displacements thereof are disclosed, as are methods for accomplishing the same.
