Counter Balance SupportsWhen the total weight of the column is more and it can not be supported on fix support at the bottom, excessive weight is relieved by counter balance supports. The maximum force require to support the sealing of coupling are as under. 
The counter weight acts through two levers on the lower backing flange. The maxium lever ratio is 1:10. More than one counter balance supports can be used to relieve the excessive load keeping minimum force require to support the sealing of coupling. 
GROUTING OF BASE  1. The one Cast Iron BASE and four foundation Bolts, each with 2 nuts.  2. Fit the bolts in BASE so that base is raised upto 150mm from head of bolts.  3. Put this assembly on the floor and prepare a rough surface for proper bonding of grouting.  4. Make a concrete block over the bolt of about 220 x 200mm upto the base of BASE i.e. 150mm high.  5. Prepare separate block for each BASE instead of making one big common block For all BASES. Contact UsShiva Scientific Glass Pvt.
