The present finding concerns an automatic lifting hook of the type made up of a hook-shaped body (1), provided with a strap (2), hinged on a pin (3) and suitable for performing a swinging movement that closes the opening portion (4) of the hook and of an upper connection part (5) consisting of an eyelet, a fork, a plate or another device suitable for the purpose. Such a hook (100) in particular is characterised in that the hook-shaped body (1) and the upper part of the connection part (5) form two separate elements, which are reciprocally held through an intermediate shaft (6), arranged in a coaxial manner with respect to the two aforementioned elements (1,5), said shaft moving axially, moves the strap (2) for closing the opening portion (4).

A hook (1) comprises a pair of hook bodies (2, 2), a pair of hook portion (3, 3), a movable pressing portion (5), an operating portion (7) and a link unit (8). The hook bodies (2, 2) are formed of two plates disposed apart from each other, respectively. The hook portions (3, 3) are integrally fixed to lower ends of the hook bodies (2, 2), respectively. The movable pressing portion (5) is rotatably supported between the hook portions (3, 3). The operating portion (7) is subject to a tension load of a hoist. The link unit (8) has both ends rotatalby connected to the movable pressing portion (5) and the operating portion (7). If the operating portion (7) is pulled upward, the movable pressing portion (5) presses a wire harness (WH), which is hooked to the hook portion (3), against the hook portion (3).

In the logging and other handling operations, a cable is often looped about the elongated object and cinched tight through a choker hook assembly in order to transport the objects. A remotely controlled hook assembly has a body (4), including an eye (6) for the passage of the cable. Encased within the body is a slidable pin (40) that serves to lock the latch arm and therefore the end of the cable. A positioning means is also within the housing and serves to rotate a catch member (64) allowing the slidable pin to move downwardly, thereby releasing the latch arm and cable. A pair of appropriately sized and located springs (56, 58) serve to both move the sliding pin downwardly and to bias the pin upwardly. A radio controlled servo (78) may be used as the positioning means.

The invention relates to a device having a hook (5) for suspending an object (7), comprising a joint head (1) having two flanks (2, 3) between which a swivel pin (4) runs, about which the hook (5) is pivotally mounted by a hub section (6) between a closed position pivoted to the joint head (1) for suspending the object (7) and a release position pivoted away from the joint head (1). A locking unit having a locking pin (8) that engages in a locking recess (9) on the hook (5) in the closed position, and an actuator (11) for unlocking the locking pin (8), a receiver (13) for a remote control for activating the actuator (11), and a power source (14) for supplying power to the receiver (13) and the actuator (11) are also provided. In the closed position, a spring force is active between the hub section (6) of the hook (5) and the pivot axis (4) in the radial direction. If a predetermined load (Lo) engaging on the closed hook (5) is exceeded, the receiver (13) and/or the actuator (11) is deactivated.
