Short description: Large hydraulic excavator manufactured by Caterpillar

A Caterpillar 345C L Excavator parked on a residential construction site in South Florida.

The Caterpillar 345C L is a large hydraulic excavator manufactured by Caterpillar Inc. The 345C L, with 345 hp (257 kW) of net flywheel power, is classified as a large excavator by Caterpillar. In Caterpillar's naming conventions, the last two digits indicate the excavator's weight in metric tonnes. The 345C L is not named after its horsepower. Rather, it is a coincidence that both use the number 345. Caterpillar currently produces the 300 series, including the 345C L.
