The system has a compensation cylinder (14) including a compensation piston (10) with a rod (1) in a lower chamber (C1), which is fastened to a pusher. The cylinder includes a safety piston (9) in an upper chamber (C3), where the safety piston has a safety device function during breakage of the rod of the compensation piston. Balancing force of the system is increased closer to a lower dead point during a pusher movement. A compensation chamber (C4) is provided in an outer cylinder (15). The lower and upper chambers are supplied with compressed air via lower and upper passage holes (2, 6). |
