Abstract
An apparatus (2) and a method for attaching a cone-shaped crushing mantle (4) of a cone crusher (100) to a carrier cone (6) of the cone crusher (100) and for detaching the crushing mantle (4) from the carrier cone (6) are provided. The apparatus (2) comprises a hydraulically actuated pre-tensioning actuator (24) adapted for pressing the crushing mantle (4) against the carrier cone (6) in a pre-tensioning process in the axial direction prior to tightening attachment screws (18) in the head region (20) of the carrier cone (6). The hydraulic pre-tensioning actuator (24) comprises a pressure chamber (26) for receiving a pressurized hydraulic medium and a piston (28) limiting the pressure chamber (26). The hydraulic pre-tensioning actuator (24) is applied externally to a pressure plate (10) during the pre-tensioning process, such that a piston rod (36) of the piston (28) or a rod-shaped element attached thereto extends through the central opening (14) of the pressure plate (10) and is attached to the head region (20) of the carrier cone (6), wherein the pressure chamber (26) and the piston (28) of the hydraulic pre-tensioning actuator (24) are located on a side of the pressure plate (10…
