Abstract
560,463. Grab-forks. PARRY,. R. H. S. Sept. 24, 1942, No. 13439. [Class 78 (iv)] A grab for lifting entangled material, such as steel turnings, bars, tubes or the like, or masses of rock-like materials, comprises a pair of fork-like bucket sections each composed of a plurality of approximately L-shaped bars 5 or 6 pivotally mounted at their bends 7, and spaced by sleeves or washers 8, 8<1> on transversely-arranged bars 1, 2 held apart by tiebars 3, 4, the upper horizontal legs of the bars 5, 6 being spaced by sleeves &c. 11, 11<1> on tie-bars 9, 10 and the vertical prong-like legs being tapered or pointed and preferably serrated. In use, the grab is lifted by a hook 16 on the lifting chain &c. of a crane, engaging a ring 13 on a chain 12 connecting the tie-bars 3, 4, the bucket sections thus being held open, and the grab is dropped on to the material to be lifted. The hook 16 is then engaged with a ring 15 connected by chains 14 to the bars 9, 10 and the subsequent lifting effort causes the L-shaped bars 5, 6 to pivot on the bars 1, 2 so that the vertical legs approach each other and hold the material. The grab may be used on a double rope crane, separate ropes being connected to the rings 13, 15.
