Model overview

The Caterpillar 320D L is the long-undercarriage version of the 320D generation crawler excavator, a 20 to 22 tonne medium excavator built for general earthmoving, trenching and site work. The 320D generation followed the 320C and carried a Cat C6.4 or C6.6 ACERT engine depending on build year, delivering around 103 to 110 kW (138 to 148 hp) net. The L designation adds extended, wider track shoes over the standard undercarriage (700 mm versus 600 mm), which lowers ground bearing pressure and increases stability and lift capacity on soft or uneven ground, at the cost of a higher operating weight than the standard-undercarriage 320D. Buyers should treat the L as a stability and footprint upgrade on the same 320D platform, not a separate machine class.

At a glance

Standard vs long undercarriageConfirm whether a listed 320D L has the 700 mm long-undercarriage track shoes rather than the 600 mm standard undercarriage, since this changes weight, stability and ground pressure.

Engine build yearEarlier 320D L machines carry the Cat C6.4 ACERT engine, later units the Cat C6.6 ACERT, so match the seller's stated engine and power figures to the build year.

Bucket and attachment fitBucket capacity and attachment compatibility vary by configuration, so confirm the fitted bucket against the job rather than assuming the maximum listed capacity.
