GK BLOCK FOUNDATIONISOLATION SYSTEMUNISORB RG FOUNDATIONISOLATION SYSTEM

LOW FREQUENCYFOUNDATION BLOCK

The UNISORB RG is a highly cost effective foundationisolation system designed for extremely heavy loadsand can be applied to a broad range of equipmentrequiring a high degree of isolation. This system utilizes a UNISORB Titan Shock Pad to provide vibration isola-tion and the UNISORB Fixator to provide load sensingand load distribution. These functions are accomplished by adjusting the Fixator using a torque wrench. The steel frame of the RG housing is designed to permitservice of the unit without the requirement of an expen-sive jacking system for lifting the foundation as required for spring systems. In most cases it is also possible toservice the unit without taking the machine out of ser-vice. The RG System can be provided with load ranges from 30,000 to 150,000 lbs. per mount. The GK Block is specifically used for isolating equip-ment where low interfering frequencies are encoun-tered. They are typically used under concrete founda-tions supporting either source or sensitive machines.The highly specialized rubber compounds used, uniquegeometrical shape, and carefully controlled load deflec-tion characteristics make the GK Block an excellentlower cost alternative to installations normally required to reach system natural frequencies as low as 3.5 hzvertical and 1.5 hz horizontal. GK Blocks are rated from4,000 to 18,000 lbs. Examples of GK Block Applications Include:

•

Coordinate measuring machines.

•

Precision optical equipment.

•

Precision grinders.

•

Vibrating conveyors.

•

Lab equipment.

•

Presses.

•

Equipment operating in environments of unusuallysevere shock and vibration conditions.

TYPICAL RESULTS OF ISOLATED INERTIA BLOCKFOUNDATION ENGINEERING VIBRATION ANALYSIS

17 The charts show a vibration survey performed byUNISORB on an existing isolated inertia block installation. A grinding machine performing a roughgrind operation on a crankshaft was installed on aninertia block isolated as shown on the typical IB-500 inertia block installation details. During the rough grindthe machine generated vibrations were measured onthe foundation. The left chart shows an average of 64 of these measurements.Vibration measurements were also taken on the con-crete floor immediately surrounding the isolated foun- dation. The right chart shows an average of 64 of thesemeasurements which were also taken simultaneous tomeasurements on the left chart.A comparison of the two charts is a graphic illustrationof the high degree of isolation efficiency provided byUNISORB inertia block isolation materials.
