When 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 load which can be supported on fix
support and minimum force required to support the sealing of coupling are
as under.
| DN of Column | Permissible Weights (Kgs) | Force Required For Sealing (Kgs) |
| 225 300 400 450 600 |
200 380 500 700 1000 |
25 32 55 70 110 |
The counter weight acts through two levers on the lower backing flange. The maximum lever ratio is 1:10. More than one counter balance supports can be used to relieve the excessive load keeping minimum force required to support the sealing of coupling.
