A hook assembly comprises a hook member and a latch member. The hook member has a body and a hook point defined at one end of the body. The hook point is spaced apart from and opposite a catch tab protruding from the body at an intermediate point on the body. A hook gap is defined between the hook point and the catch tab. The latch member is pivotably coupled to the body and movable between an open position in which the latch member is retracted toward the body and a closed position in which the latch member is pivoted to contact the hook point and thereby close the hook gap. The latch member defines a latch engagement opening sized larger than at least a portion of the catch tab so that the latch member is retractable past the catch tab in the closed position.

An end effector includes a body having a cavity located therein. The body partially encloses the cavity and includes an opening through the body to the cavity that is sized to receive a hanger hook. A hooking structure is located within the cavity. A latch is movably received by the body. The latch has a closed position that reduces the size of the opening and an open position that increases the size of the opening.

A hook device includes a central shaft which extends in a first direction, and a first locking portion and a second locking portion which are disposed such that the central shaft is interposed therebetween, in a second direction orthogonal to the first direction. The first locking portion and the second locking portion are connected to the central shaft in a state where the first locking portion and the second locking portion are not rotatable independently around an axis extending in the first direction and are rotatable around an axis extending in a third direction different from the first direction and the second direction.

An apparatus for removing and/or installing a side guide of a trailer-mounted boat capture system for guiding a boat onto the trailer, the apparatus comprising: an outboard post pivotally attached to an upper support rail of the side guide; two inboard posts, each pivotally attached to the side guide proximal to where the side guide is attached to the trailer via first pins, wherein each inboard post includes a manual leveling jack; an attachment point on the side guide suitable for attaching a winch cable from a boat held in the boat capture system; and second pins attaching the side guide to the trailer such that when the first pins are removed the side guide is free to pivot around the second pins from an upright position towards a support surface.

A device for lifting and transporting a load attached by a sling includes a hook comprising a throat opening intended to receive a loop on a sling. The device includes a latch that can pivot between an open position and a closed position in which said throat opening is obstructed. The device includes a locking device including a locked position in which said locking device prevents the latch from turning in the closed position, and an unlocked position in which the latch can rotate; a lever including a loaded position in which said lever holds the locking device in the locked position and a released position in which said lever does not hold said locking device. A rotation of the latch from the closed position to the open position triggers the lever from the loaded position to the released position.
