Inertia Pouring Frame
licensed in 1992 by
Type IPF
Inertia Pouring Frame has been developed
for use with machines which produced high
level of Vibration or those which are
subjected to external forces or are simply
unstable when mounted directly on high
deflection/low stiffness helical spring or
rubber Mountings for giving extremely high
degree of vibration isolation without
excessive motion.
Vibration attenuation is dependent on base
rigidity as well as Isolator deflection. If the
base becomes distorted because of weight
distribution, belt pull or the torque
introduced by a direct drive, the equipment
will wear out more quickly and vibrate
excessively because of the loss of the
alignment.
Base RESONANCE is another difficulty
that can result from poor frame
construction, If base members are light and
long, they will tend to RESONATE at low
frequencies that may be sympathetic or
close to the operating speeds of the
mounted equipment.
The Frame is of fully welded construction
with reinforcing bars and can be straight
away filled at site with concrete to become
rigid floating concrete platform.
The inertia weight of the concrete will also
reduce the operating amplitude of
equipment.
Viscous Damper can be incorporated to
further control motion during transient
conditions such as machine run-down and
machine faults.
Height saving brackets can be used to
further lower the Centre of Gravity for better
stability.

Frame weights include concrete at 2245Kg/m and mounting
selections are based on 4 mountings per frame allowing 50%
additional weight for the equipment to be supported. Nominal
NOTE: For frame sizes coloured grey additional mountings 25mm deflection Isolators, however the exact deflection will
should be used or a deeper frame selected. vary depending on the applied load.
Design and Installation Notes:-
¿The equipment should be located on the frame such that the load is evenly distributed over the mounting positions.
¿Equipment and ancillary parts should not overhang the frame and hold down bolts MUST NOT be less than 100mm from
the outer edge of the frame.
¿All connections to the equipment should incorporate flexible sections and pipe work etc must be independently
supported.
¿Grade 25 (25N/mm2) concrete should be used as a minimum strength requirement for filling Inertia Pouring Frames.
¿When filling frames with concrete, positions on flat and level fully supported shuttering board with a polythene
separations layer. Mountings should NOT be fitted at this stage.
