ABSTRACT:
This improved cable-scooping hook device is capable of automatically loading and unloading cargo, used for transporting suspended cargo. It comprises two relatively flat members, pivoted by a pin near their mid-section and weighted on top to help force its lower portions to separate when the cargo is lowered onto a platform and the hoist cable tension is reduced. Its lower mating ends or jaws are protected from high compressive stresses by inwardly protruding hammers. To prevent the hook device from tipping over upon touchdown, at least one swivable tubular support member staddles the device. For secure suspended cargo retention, its lower portions may have an integrated electromagnet producing lines of force when energized to keep its jaws engaged. The weights on top can be reduced using springs to counter the closing torque about the pivot pin, to enable the device's lower portions to disengage automatically. The addition of a tongue fastened to the underside of a selected jaw assists in scooping up a load cable. The tubular support member's legs may be flexible in length.
