【発明の名称】引綱掘削機
Document Type and Number:
Japanese Patent JPS587767
Kind Code:
B2
Abstract:
Separate torque converters are selectively clutched to the hoist and drag drums of a dragline machine with a selectively engageable clutch providing a power interlock of the output of both torque converters to either one of the drums as desired. Another clutch may be engaged to interlock the two drums together for joint operation by one of the torque converters. Dragline holdback may be achieved by the drag drum brakes, the drag drum converter or the drum interlock thereby providing the operator with considerable flexibility in controlling the path of the drag bucket during hoisting.
