An apparatus for transferring cargo between first and second bodies which are movable relative to each other where a hoist for raising and lowering cargo through a hoist line is mounted on one of the bodies includes a linkage for connecting the two bodies. The linkage is pivotally connected to the bodies for accommodating relative movement between the bodies. A guide is located between the hoist line and one of the bodies for engaging and guiding the hoist line. A trolley which is movable along at least a portion of the linkage engages the hoist line on the side opposite the guide and moves the hoist line along the linkage between the guide and the other body while the line changes length so that cargo connected to the hoist line can be moved along the linkage. The linkage includes a plurality of arms in addition to hydraulic cylinders useful for compensating motion between an articulated connection and a second body.

An apparatus for transferring cargo between first and second bodies which are movable relative to each other where a hoist for raising and lowering cargo through a hoist line is mounted on one of the bodies, comprising linkage means for connecting the two bodies, pivot means for pivotally connecting the linkage means to the bodies and having motion compensation means for accommodating relative movement between the bodies; and trolley means movable along at least a portion of the linkage means for supporting the hoist line, and moving the hoist line along the linkage means between the two bodies so that cargo connected to the hoist line can be moved along the linkage means from one of the bodies to the other one; the linkage means including a first arm pivotally connected to the first body for pivotal movement through a horizontal plane, a second arm pivotally connected to the first arm for pivotal movement through a vertical plane, and a third arm pivotally connected to the second arm for pivotal movement through a vertical plane; and secondary platform means carried by the linkage for providing a substantially horizontal planar work surface below an end portion of the third arm in the vicinity of its connection to the second arm.
