摘要 |
A permanent rigging pedestal for barges and the like in the form of a base, a pair of spaced apart generally parallel vertical posts fixed at one end to the base, a gusset plate connecting the posts, a vertically extending coaxial pin fixed above each post, each pin adapted to receive the eyebolts of one or more ratchet turnbuckles and a locking bar connecting the pins at their upper ends to prevent removal of the turnbuckle eyebolts. In the preferred embodiment each pin carries a pair of ratchet turnbuckles, one ratchet turnbuckle having a pair of spaced eyebolts forming a U-shaped clevis between which the eyebolt of the other ratchet turnbuckle fits to engage the pin.
