ABSTRACT:
A continuous type of bucket unloader especially useful in transferring bulk cargo from a floating ship to shore has a main loading boom with an endless bucket chain pivotally suspended at its shipside end and which is pivotally mounted between its ends on a horizontal pivot on the shipside end of a lever which, in turn, is pivotally supported on a horizontal pivot between its ends on a support structure that, in turn, is fixed on a gantry. The landside ends of the boom and the lever are counterweighted and adjustably connected to each other whereby the angular relation of the boom to the lever on which it is mounted may be varied, and the lever, in turn, has a fluid pressure cylinder and piston unit for pivotally adjusting its angle relative to its support on the gantry. The combination provides a wide range of adjustment for the continuous bucket chain which, in turn, discharges bulk cargo that it elevates from the ship's hold to a fixed receiving chute on the gantry, and the arrangement tends to maintain a substantial condition of balance crosswise and lengthwise of the wheel bearings of the gantry trucks in all positions of the continuous bucket conveyor.
