Claim 11:
12. A snatch block comprising:
a first stationary cheek residing in a first plane on a first side of an internal space of the snatch block;
a movable second cheek residing in a second plane on an opposing second side of an internal space of the snatch block in spaced and opposing relation to said stationary first cheek, said movable second cheek being movable between a closed position and an open position;
at least one sheave rotatably supported on said first and second cheeks in the internal space therebetween, and said sheave being rotatable around a rotation axis that transversely penetrates said first and second planes; and
a crown residing at a position spaced outwardly from a periphery of the sheave in a radial direction relative to said rotation axis, thereby delimiting a swallow that remains open between the sheave and the crown to accommodate passage of a rope therethrough,
wherein:
said movable second cheek is movable, relative to the stationary first cheek, between the closed position, in which the movable second cheek closes off the swallow at the second side of the interior space, and the open position, in which an access gap opens into the swallow to enable loading of the rope into the swallow via said access gap; and
a dual-release locking mechanism that is configured to normally lock the movable second cheek in the closed position, and comprises two separate locking members of independently movable relation to one another between respective locking and release positions, and respectively associated with two separately actuated releases that reside at discretely separate locations on the snatch block and require physical exertion of separate actuation forces thereon to respectively release the two separate locking members of said dual-release locking mechanism.
