Isolated Foundations and Inertia Blocks

Isolated foundations and inertia masses are typically free-floating concrete and/or steel masses that are supported by vibration and shock isolators. Isolated foundations are typically used to protect precision machinery or equipment from incoming vibration and shock. Whereas, inertia masses are typically used to add mass to a machine to control motion and to improve isolation of transmitted forces to surrounding areas.

Elastomer blocks, vibration mounts, pad material and coil spring isolators are commonly used as isolation elements under isolated foundations and inertia blocks.

Coil Spring Mounts

Isolator models VSM and SV are excellent low-frequency coil spring isolators designed for use in isolated foundation and concrete slab applications. These mounts are also used in inertia block applications under forging hammers, stamping presses, generators, etc.

Typical natural frequencies range from 2.5 to 6 Hz for very effective vibration and shock isolation.

Elastomeric Isolation Blocks

VB™ Isolation Blocks are elastomeric cushions also designed for use under concrete slabs and isolated foundations supporting sensitive equipment that needs protection from incoming vibration and shock. They also work to protect neighbors and surrounding area from a source of vibration and shock.

VB Elastomer Isolation Blocks have individual load ratings from 8,000 to 47,000 lbs. and can be configured to have dynamic natural frequencies as low as 7.5 Hz.
