IMPACT DEVICE AND METHOD OF DISMOUNTING THE SAME

摘要

The present invention relates to a method for separating a device from an impact device and a crushing device. The impact device (12) has a bush (16). A percussion piston (21) is formed inside the bush. The impact device is arranged inside the impact device space formed in the frame (20) of the crushing device (15). The percussion piston provided with a full shoulder (33) is allowed to transfer the separating force (FB) in the return direction (B) from the percussion piston to the bush. Thus, the bush is extracted from the frame by the impact piston.
