Caterpillar M315D Excavator Specs

Category: Excavators ➔
Manufacturer: Caterpillar ➔
Model: M315D ➔

The Caterpillar M315D is a wheeled excavator in Caterpillar's M Series lineup, designed for urban construction, roadwork, utility installation, and general earthmoving. It is powered by a Caterpillar diesel engine and uses a hydraulic system configured for digging, lifting, trenching, and material handling. The M315D typically features a cab with operator controls, boom and stick options, and compatibility with multiple work tools. Its wheeled undercarriage provides mobility on paved surfaces and job sites where travel between work areas is required. The model is commonly used in applications that need excavator performance with faster repositioning than tracked machines.
