Komatsu PC210 vs Cat 323 | Dimensions

Compared to the Cat 323, the Komatsu PC210 has a narrower width, so it will fit on narrower land and it will be more maneuverable on the site. The Komatsu PC210 is also shorter and lower which can make it easier to transport and work in tight spaces.

The Komatsu PC210 has a longer wheelbase than the Cat 323 which gives it more stability at high speeds.

The PC210 weighs a bit less than the Cat 323, but this won’t necessarily translate into a significant difference in performance, as it depends on several other factors as well.

Both machines have similar ground clearance – the lowest point from where they can climb over an obstacle, so both should perform similarly in rough terrain.

When climbing up slopes, the angle of departure is an important factor as it determines how steep of an incline can be climbed without bottoming out. In this regard, the Komatsu PC210 has a better angle of departure compared to the Cat 323 (37 degrees vs. 30 degrees).

Despite their differences in size and weight, both machines’ turning radius are within 5%, so you won’t notice any significant difference in their maneuverability on your jobsite.

Komatsu PC210 vs Cat 323 | Weights

This is a very important piece of information to know when it comes to operating these machines. The Komatsu PC210-10 weighs in at 40,855 lbs while the Cat 323D L weighs out at 43,532 lbs. If you have the same engine on these machines, which you would expect, then the difference is 2,677 lbs!! This can make a BIG difference when it comes to weight restrictions and applications.

Another thing to think about is that the Komatsu PC210-10 has a full counterweight while the Cat 323D L does not have one and relies on the bucket/thumb as part of its counterweight. The problem with this is if you use a thumb for your application then you will be tipping the scale in favor of the Cat 323D L.

So if you are limited on weight restrictions, but want power in your excavator then I would definitely go with the Komatsu PC210-10.

Chose Komatsu PC210 vs Cat 323

I am not an expert when it comes to the differences between a Komatsu PC210 and the Cat 323. My experience with these machines is very limited and consists of working with older Cat 315s, 315Ls and older Komatsu 210s. I have never run the newer models, so I am speaking from what I have seen over the years.

I was talking to a friend who has worked for a local equipment dealer for years and he started asking me about differences in their equipment. He’s worked on all brands and he asked me if I could tell him some differences between them. I gave him answers based on what I know of their older models.

The most noticeable difference that I could think of is the way they swing. The Cat machines seem to have more of a floaty feel when you swing, especially if you are digging in soft dirt or something similar, but it doesn’t seem like they swing as fast as some of the other brands. Komatsu seems to swing faster, but maybe not as freely. The Hitachi machines in my area seem to swing the fastest, but they don’t seem to float as much as the Cat machines do.
