Abstract:
An unloading device includes a support jib, for example, of a type which is adapted to be carried by a gantry, which is movable along a pier or dock for unloading vessels. The outer end of the support jib includes a vertical conveyor support member which has a roller bearing assembly supported thereon on which is rotatable a return wheel of the vertical conveyor. The vertical conveyor also includes a vertical support rod or support member which is pivoted on the vertical conveyor support member for pivotal movement about a horizontal axis below the return wheel. The vertical conveyor support arm carries a plurality of roller guide means for an endless conveyor member such as a bucket conveyor which is also guided over the return wheel. One or more drive motors are advantageously carried either directly on spaced circumferential mountings around the support member and the jib or on an upward extension of the support arm, and each carries a driving pinion which is engageable with an annular gear which is affixed to the return wheel. A plurality of separate drive members may be located at spaced locations around the circumference of the internal drive gear connected to the return wheel and they may be situated either directly on the jib support member or on the vertical conveyor arm which may be supported on one of the rings of the rotatable support bearing.
