Komatsu's hydraulic shovels with crawlers have the model numbers that start with PC. The letter "P" indicates hydraulic shovels in general, because they used to be called "Power Shovel" a long time ago. The letter "C" stands for "crawler". Hydraulic shovels with wheels have the model numbers that start with PW, and "W" stands for "wheel". The numbers after those letters indicate the weight of the machine.

The bigger the machine is, the bigger the number gets. The smallest machine has the model number PC01, and it weighs 300kg (660 lbs). The biggest one is PC8000, and the machine weighs 720tons!!
