Abstract
A double-reeved lifting device includes a lower reeve block secured to a lifting hook and an upper reeve block, wherein the two reeve blocks are part of a mechanical reversible connection system to be reversibly configurable between a connected configuration and a disconnected configuration, with a locking mechanism and a complementary locking structure supporting a locking member. The locking mechanism includes a chassis having a locking channel provided with a mouthpiece through which the locking member can enter and exit and can slide in the locking channel respectively during a relative approach and distancing between the two reeve blocks. A pawl is pivotally mounted on the chassis to pivot inside the locking channel and is provided with a free end capable of being engaged with the locking member. A thrust stop assembly and elastic return member push on the pawl.
