Abstract
The present invention concerns a turntable of a rotary crane of the king post type having a pylon anchored to a base plate, platform, or similar base. The turntable has a support frame that can slide above and is suspended from the pylon, coupling devices connected to the support frame to permit the coupling of a crane boom, and support devices to allow the support frame to revolve around the longitudinal axis of the pylon. The support devices have an upper support for the suspension of the support frame on an upper end section of the pylon, and a lower support for the suspension of the support frame on a lower section of the pylon, with the lower support having a bearing journal that encircles the pylon. According to the invention, the bearing journal of the lower support is designed to be divided. The support frame has an open longitudinal side through which the support frame with divided bearing journal can slide radially along the pylon.
