Abstract (en)
[origin: US2022081267A1] 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 include reversible connection means adapted to be reversibly configured between a connected configuration and a disconnected configuration. The reversible connection means include a locking mechanism and a complementary locking structure having a frame securely supporting a bolt. The locking mechanism includes a chassis having a locking channel provided with a mouthpiece through which the bolt is configured to enter and exit and slide in the locking channel respectively upon a relative approach or distancing between the two reeve blocks, and at least one latch pivotally mounted on the chassis so as to pivot inside the locking channel, the latch provided with a free end adapted to engage with the bolt.
