Abstract
A rigging device includes a fixture having opposed first and second ends, opposed upper and lower faces, and a bracket extending away from the upper face of the fixture between the opposed first and second ends of the fixture to engage a hoist line of a crane. A support is mounted to the fixture proximate each of the opposed first and second ends on either side of the bracket extending away from the lower face of the fixture terminating with an engaging element movable between a disengaging position and an engaging position.
Claims18
A rigging device, comprising:
- a fixture having opposed first and second ends, opposed upper and lower faces, and a bracket extending away from the upper face of the fixture between the opposed first and second ends of the fixture to engage a hoist line of a crane;
- and
- a support mounted to the fixture proximate each of the opposed first and second ends on either side of the bracket extending away from the lower face of the fixture to an engaging element movable between a disengaging position and an engaging position.
The rigging device according to claim 3, further comprising an operative coupling between the supports, wherein rotation of one of the supports imparts rotation to the other one of the supports.
A rigging device, comprising:
- a fixture having opposed first and second ends, opposed upper and lower faces, and a bracket extending away from the upper face of the fixture between the opposed first and second ends of the fixture to engage a hoist line of a crane, the bracket having a first side directed toward the first end of the fixture and a second side directed toward the second end of the fixture;
- substantially coextensive first and second supports;
- the first support mounted to the fixture, between the first end of the fixture and the first side of the bracket extending away from the lower face of the fixture to a first engaging element, for rotation between a first position disposing the first engaging element in a disengaging position, and a second position disposing the first engaging element in an engaging position;
- the second support mounted to the fixture, between the second end of the fixture and the second side of the bracket extending away from the lower face of the fixture to a second engaging element, for rotation between a first position disposing the second engaging element in a disengaging position, and a second position disposing the second engaging element in an engaging position;
- and
- the first support operatively coupled to the second support, whereby rotation of the first support imparts rotation to the second support.
A rigging device, comprising:
- a fixture having opposed first and second ends, opposed upper and lower faces, and a bracket extending away from the upper face of the fixture between the opposed first and second ends of the fixture to engage a hoist line of a crane, the bracket having a first side directed toward the first end of the fixture and a second side directed toward the second end of the fixture;
- and
- a first support having a first extremity and an opposed second extremity formed with a first engaging element;
- a second support having a third extremity and an opposed fourth extremity formed with a second engaging element;
- the first support mounted to the fixture between the first end of the fixture and the first side of the bracket for rotation between a first position disposing the first engaging element in a disengaging position, and a second position disposing the first engaging element in an engaging position, the first extremity of the first support extending away from the upper face of the fixture and the second extremity of the support extending away from the lower face of the fixture;
- the second support mounted to the fixture between the second end of the fixture and the second side of the bracket for rotation between a first position disposing the second engaging element in a disengaging position, and a second position disposing the second engaging element in an engaging position, the third extremity of the first support extending away from the upper face of the fixture and the fourth extremity of the support extending away from the lower face of the fixture;
- and
- the first extremity of the first support operatively coupled to the third extremity of the second support, whereby rotation of the first support imparts rotation to the second support.
