For use with cranes or hoists, the traditional shackle-bolt through-hole in the shackle-bar is elongated into a slot. A sub-unit comprising a cell-block, a load-cell, a load-block, and one of the shackle-bolts, is placed in the slot. The load-cell, of suitable size, is housed in a very robust manner, and yet the load capacity of the shackle-bar is unaffected by being so modified.
