allowable load of channel

allowable load of channel
i want to make  rectangular structure of channels how can i calculate the allowable load of channel. for example a tube bundle of heat exchanger is about 12  tonnes what size of channel be requred for this weight, what is calculation procedure
you have not provided enough information to solve the problem.  need to know, minimum....
span of channels
configuration of load
any wind load considerations
area of unit (bottom area and all sides)
support conditions of channels
curious as to why you would use a channel.  in heat exchanger support applications, there is most likely thermal growth between the saddles.  therefore one end will act like an anchor.  a channel is not the moste efficient shape to take the lateral load.  this will need to be braced.  like ron said above, more information would need to be given.
dear ron,ag89
we want to design a trolley for transporting a tube bundle of heat
exchanger during annual turn around of our plant.i am a mechanical engineer
and not familiar with steel structure calculations.
here is reply of your quiries
span of channels   2mx2m (length x width)
load configuration    (say uniformly distributed load)
any wind load considerations  (100 km/hr)
area of unit (bottom area and all sides)sides 4sqm
support conditions of channels (see sketch)
