Abstract
A remotely controlled rotatable crane for loading logs on a live deck. The crane includes a carriage having a horizontal bed rotatable on a circular track about a verticle axis, the bed carrying a truss assembly extending upwardly and radially outwardly from the bed. The distal end of the truss assembly carries a vertically movable and rotatable grapple. A winch and cable raises and lowers the grapple. A counterweight is disposed on the carriage to counter balance the truss assembly. Electrohydraulic controls operate the winch for raising and lowering the grapple, controls the rotation of the grapple about a vertical axis and its opening and closing and controls the movement of the carriage about its vertical axis. Hydraulic motors also drive wheels on the track for rotating the carriage about a vertical axis.
