WhatsApp: +86 18203695377The design of a machine foundation is more complex than of a foundation which supports only static loads. If a machine is rigidly bolted to the floor, the vibratory movement of the machine itself may be reduced, but the vibration transmitted to the floor will be large. This may produce harmful effects even at large distances.
