Abstract
An apparatus (2) for lifting a crushing mantle (4) of a cone or gyratory crusher is provided. The crushing mantle (4) has a first central axis (26) and an opening (10) with a clearance width (w) in its top region (12) surrounding the first central axis (26). The apparatus (2) comprises a plate-shaped lifting member (8) having a second central axis (18) and adapted to be attached to the top region (12) of the crushing mantle (4), wherein the first central axis (26) coincides with the second central axis (18) when the plate-shaped lifting member (8) is attached to the crushing mantle (4). The plate-shaped lifting member (8) includes at least one attachment member (32) adapted to be attached to a suspension assembly (36), in order to lift the plate-shaped lifting member (8) together with the crushing mantle (4) attached thereto. The plate-shaped lifting member (8) has a first dimension (d1) in a first direction being smaller than the clearance width (w) of the opening (10) in the top region (12) of the crushing mantle (4); and the plate-shaped lifting member (8) has a second dimension (d2) in a second direction being larger than the clearance width (w) of the opening (10) in the top r…
