Twin pulley block
Two grooved sheaves inside an open side frame.
A twin-sheave pulley block with raised wheel flanges, a shared axle, open side cheeks, contrasting hubs, and an upper attachment eye. The grooves and bores are actual mesh geometry. This is a static assembly study without rope, motion constraints, bearing specifications, or a working-load rating.
