315=35"
It is 315 mm wide.
The 315 is a model size of the excavator. Cat uses the last 2 numbers ( the 15 in the 315) . In this case the 15 means 15 metric ton. If the machine was a 320 it would be 20 metric ton and 325 would be 25 metric ton and so on. Most other brands of excavators use the first 2 numbers in the model number. Like Deere's 160 you would use the first 2 numbers the 16 and that would mean 16 metric ton and the 200 Deere would be a 20 metric ton machine and so on!
