A patient hoist is provided on a trolley which tides along a track, with the hoist being powered by a conductor extending along the track. A contact carrier is loosely fit within the trolley, and it bears a contact which elastically biased against the track conductor, with die contact being in electrical communication with the hoist: The contact carrier is tree to laterally displace with respect to the trolley so that it (and its contact) follows the contour of the track, with the contact remaining in electrical communication with the track conductor. |
