The TWIN HAMMER Mechanism consists of 2 hammers in a closed system that rotate around the shaft. This system creates enormous torque even within the first revolutions of the rotor, since the hammers can hit at the same time from both sides of the shaft. This reliable twin hammer impact system is a very durable system and particularly suitable for long operating cycles. A further advantage is that the system consists of few individual parts which makes it long lasting and very easy to service.
