Disclosed is a delivered article loading apparatus, which is mounted to a lifting wire installed at the drone to be capable of lifting. The delivered article loading apparatus includes a lifting body installed at a lower end of the lifting wire; and a disposable hanging body coupled to be selectively connected to or separated from the lifting body and having a hooking unit at a lower portion thereof, wherein the lifting body and the disposable hanging body are automatically separated by a mechanical or electromagnetic interaction therebetween.

A helicopter load hook has a release mechanism that can be mounted in a fixed position in a housing for controllable identification and release of a swivel movement of a hook. The release mechanism includes a magnetic switch and a drum that can rotate. The release mechanism also includes at least one latching piece, which can be swivelled about a latching piece axis of rotation and at least one force receiver, which can be swivelled about a swivel axis, together with a pin. The pin can be connected with a locking lug on the drum together with a hook follower on the hook, such that an indirect connection between the hook and the drum, or more particularly, the magnetic switch, can be achieved, and any direct contact between the hook and the magnetic switch is eliminated. In the closed position of the hook the pin makes any swivelling movement of the hook impossible.

A lifting hook (14) provided with a remotely operated safety latch (12), wherein remote operation is used to both open and close the latch. The latch can be magnetically held (36) in the open position to connect and disconnect the load from the hook. Furthermore, an indicator (42) can be provided to indicate when the latch is latched and unlatched. The latch can be operated with lines with a first line (62) controlling one direction of movement of the latch and a second line (64) controlling a second direction of movement of the latch.

The invention relates to a hook (10), which may for example be used with a crane to lift heavy loads. In one embodiment, the hook may have a load-bearing portion (12) and an arm portion (14) where the arm portion can pivot relative to the load-bearing portion between open and closed configurations and may have a locking mechanism (20, 21, 29, 30, 32) that can lock the arm portion with respect to the load-bearing portion in the open configuration of the hook, in which configuration the arm portion and the load-bearing portion together define a discontinuous boundary. The hook may also be provided with a suspension portion (74), and the suspension portion, the load-bearing portion and the arm portion may be pivotally coupled with respect to each other.
