         orientation cable trolley and a flexible orientation cable trolley.

         direction of travel of the cable trolley. Figure 20 is a front
         orthogonal view of one embodiment of the present cable trol-
         ley, depicting the carrier of the trolley being disposed in an-
         other orientation where the seat 38 or carrier 18 is disposed
         at an angle substantially perpendicular to the direction of
         travel of the trolley 2. In this embodiment, a handle bar 42
         is fixedly attached to the support structure 4 or swivel as-
         sembly 6 using two fasteners 44. The handle bar 42 serves
         as a grasp point for a user 40 seated in the carrier to apply
         a torque to rotate the carrier 18 about the central axis 68 of
         rotation of the swivel assembly 6.
           The handle bar 42 is preferably disposed sufficiently close to
         the user 40 for easy reach but not so close as to be a barrier to
         the user 40 when rotating the carrier. In one embodiment not
         shown, at least one additional handle bar 42 is provided as
         an additional grasping point to facilitate manual rotation of
         carrier about the central axis of rotation of the swivel assem-

                                                              in another orientation.

                                                              the user applies torque to the handle. Unrestricted rotation
