Video: Cat's All-New 315 Excavator is All About Speed

Updated Apr 2, 2021

The new Cat 315 is better in every way than the machine it replaces, the 315F L. Cat has upgraded the hydraulics, engine, cab and swing drive and they've packed a lot of standard tech on this 15-metric-ton machine to help you get the job done faster.

In fact, Cat is calling the new 315 the most productive excavator ever in that 15-metric-ton size class.

We’re going to get into what’s new about this model, how they achieve some pretty substantial performance and productivity gains and how Cat is really stacking the deck here against the competition in terms of comfort improvements and standard technology.

Check out the video above for all the details, or read on below.

Cat considers the 315 a “small” excavator. As a 16-metric-ton machine, its not a compact or mini excavator, but not large enough to be considered a midsize Cat excavator. In fact, within the small lineup, the 315 slots right in the middle between the 13 metric ton 313 and the 18 metric-ton 317.

The 315 is also a compact radius machine with only 5.1 feet of tail swing radius. And with 19 feet, 6 inches of digging depth and a 23-foot max loading height, though its digging forces can’t quite match up to larger machines in the Cat lineup, the 315 is a very versatile option in that it offers comparable reach and loading heights to those larger machines while still in a very compact package.

So, while you might typically think of larger excavators for loading trucks, Cat says you might be surprised how many of these small excavators in that 30-40,000-pound size class like the 315 are doing that work on a daily basis and in use not just on residential and site prep like you’d expect but on large infrastructure and road jobs as well.

The 315 in particular is a compelling machine for roadside digging and loading due to its compact design and formidable reach.

And because of its weight and size, transportability is less of a headache as well. When the 315 is equipped with 24 inch pads, it falls within a transport width of 8 feet 6 inches, so you can throw this thing onto a tag trailer and move it between jobs with a pretty simple setup.
