Abstract

PURPOSE: To automatically control an elevator in a vertical posture convenient for taking in and out from the opening part of ship's hatch by arranging a posture controlling circuit onto the hydraulic circuit for fluctuating a bucket elevator.
CONSTITUTION: A bucket elevator 1 is swingingly supported onto the pivotal shaft 5 of a boom 2 and operated by a cylinder 7 connected with a hydraulic circuit 8. When the control valve 10 on the hydraulic circuit 8 side is positioned at neutral in blockage, and the control valve 15 on the auxiliary circuit 9 side is opened, a low oil pressure P is applied to the both sides of the piston of a cylinder 7 through a pressure reducing valve 18. The moment W×L due to the weight of an elevator 1 balances with the moment (S1-S2)×P×R due to the difference of acting surface S1-S2 on the both sides of the piston, and the elevator 1 is positioned in nearly vertical situation. When the pressure P is varied by the control of the pressure reducing valve 18, the vertical situation of the elevator 1 can be controlled finely.
