Abstract

This invention relates to a grapple (1) and a method for lifting an object having a bore (24) and a shoulder (27) peripheral to the bore. The grapple comprises a shaft (2) adapted to be lifted, a collar (6) mounted for translation with respect to the shaft, a plurality of fingers (8), each finger pivotally mounted with respect to collar (6) for movement between a disengaged configuration in which the finger extends in a shaft axial direction and an engaged configuration in which the finger extends at an angle to the axial direction and a head (4) mounted to shaft (2) and adapted to swing the fingers to the engaged configuration when the head is drawn by the shaft towards the collar.
