The new conventional tail swing, Doosan® DX42-5 is a strong performer in the 4- to 5-ton class.

This highly maneuverable excavator has a strong bucket breakout force along with excellent dig depth and reach.

Its relatively narrow width for a machine in its class provides operators greater ability to navigate through doorways, gates and other obstacles.

A roomy cab adds to operator comfort, and tall, wide windows provide the operator with excellent visibility for enhanced productivity and safety.
