Abstract: A mechanism for lifting or lowering a cable drum which includes a stand located at lateral end faces of a cable drum which is adapted to be raised and lowered. Each stand includes a foot and a pair of vertical posts carrying upper and lower crossbeams with each lower crossbeam carrying a hydraulic hoist. The lower crossbeam is selectively secured to the posts, a pin carried by each upper crossbeam is inserted into a journal of the cable drum, and each hydraulic hoist is actuated to raise each upper crossbeam and its associated pin thereby raising the cable drum.
Abstract: A coupling device including a male coupling member and a female coupling member, the male coupling member including a shank-like body having three longitudinal slots each receiving a pivot fin, a circular spring normally biasing a first end portion of each fin into each associated slot and thereby automatically placing a second end portion of each fin in its normal coupling position, the female coupling member including a fitting connected by spacer bars to a coupler ring which receives the shank-like body, the ring having an opening which causes the fins to deflect toward an unclamped position during insertion, and after insertion the second end portions of the fins are brought into clamping engagement with the ring by the biasing force of the circular spring.
