If you’re on the lookout for a reliable CAT loader size, you could be overwhelmed by Caterpillar’s gigantic product line. From a tiny little compact utility loader to heavy duty models used in a rock quarry, they have a product or series of loaders. Each of these loader series has ranges of sizes, capacities, and purposes. If you don’t know the difference in these loader capabilities and costs, you might buy a machine that costs too much for your work or that doesn’t have enough oomph for the job.
Imagine purchasing a loader that’s too small for what you’re doing in your quarry, meaning more truck loads to move, more fuel to run, and more time or equipment to keep up with what you’re trying to get done. Or on the other extreme, picture buying a giant loader for an urban job site that is so wide it can’t fit between buildings. Both of these are mistakes you’ll make if you don’t know how CAT’s Compact, Small, Medium, and Large Wheel Loader series compare to the others in real world use.
To help you make an informed choice, let’s take a look at how CAT loaders differ by size class and series, including key specifications, applications, and common models in each group.
