Abstract

See full text

A lifting apparatus (100) for hoisting a spider (200) of a gyratory crusher has a spreader (110) spanning between two leg members (120) each having an offset arm (121a), clearing arm (121b), cradle arm (121c), and securing arm (121d). The offset arm (121a) forms a second offset distance (131) with respect to an offset axis (C). The arms (121a-121d) form an opening (123) for receiving the spider (200). The leg members (120) oppose each other such that the clearing arms (121b) of the leg members (120) are provided on opposite sides of a plane defined by the horizontal axis (D) and vertical axis (A). The lifting apparatus (100) may be lowered over the spider (200), and rotated approximately 90 degrees in a direction (B) of rotation about the vertical axis (A) to cradle and support the spider (200) from below the spider (200).
