Hi,

Does any body know the footprint area of haul truck 797B (400t)? I tried to search on line, but nothing is found.

Thanks for your help!

cvg, thanks for your reply.

I check the link that you gave. Under 'dimensions', I can't find the footprint areas of front tires or rear tires.

 

RE: Footprint area of haul truck 797B

Would depend on the type of tyre used and the pressure it is pumped up for. Why not contact Caterpillar directly and ask them - they'll know.

RE: Footprint area of haul truck 797B

If you know the tire air pressure, operating weight and axle weight distribution, you can calculate the "footprint"

Might check this previous post:

I also came across this research paper:

You should show standard tires on the 797B to be 59/80R63.  See if you can locate a copy of the CAT Performance Handbook.  In addition to the specific section on the machine, there is a separate tire section that may be of help.  On second look, no luck there.  You are to consult Michelin or Bridgestone directly for 797 options.
 

RE: Footprint area of haul truck 797B

What is the purpose of knowing the footprint?  Is it equipemnt load on a concrete Pad to determine its thickness?
