A lifting machinery includes a lower reeve block and an upper reeve block, the lower reeve block hanging by a lifting rope connected to a lifting winch, and a reversible connection mechanical system to be reversibly configurable between two reeving configurations including a connected configuration and a disconnected configuration. The reversible connection mechanical system includes a locking element, a locking complementary element and an elastic return member urging the locking element to engage with the locking complementary element. The lifting machinery further includes a control/command unit configured to pilot the lifting winch and a sensor configured to measure a force on a strand of the lifting rope. The control/command unit is configured to pilot the lifting winch in a connection phase and in a disconnection phase according to the measurement data of the force on the strand of the lifting rope.
