The Caterpillar 321 is a mid-size hydraulic excavator with an operating weight of 23,527 kg and an engine output of 148 hp. It is equipped with a bucket capacity of 1.07 m3, positioning it firmly in the 20-to-25-tonne class. This class represents one of the most broadly utilised segments in the construction equipment market, balancing reach, digging force, and transport practicality.
Machines in this weight and capacity class are commonly deployed on civil engineering projects, road construction, pipeline laying, and general earthmoving operations. The 1.07 m3 bucket capacity makes the 321 well suited to bulk material handling and trench excavation. Utility contractors and groundworks specialists also regularly operate excavators of this specification for foundation preparation and site clearance.
When inspecting a used Caterpillar 321, buyers should carry out a thorough assessment of the undercarriage, including track chains, rollers, and sprockets, as these components represent a significant portion of ongoing ownership costs on any machine in this class. The condition of the hydraulic system, boom and stick pins, and bucket linkage wear should be evaluated carefully. A full service history review, oil sampling analysis, and a live operational test covering all functions are strongly recommended before purchase. Structural inspection of the boom and stick for cracks or weld repairs is also advisable.
The European market average for the Caterpillar 321 stands at EUR 74,500. Buyers evaluating this machine should consider comparable models in the same class, notably the Komatsu PC228 and the JCB 220X, as these represent the primary competitive alternatives at similar operating weights. Availability and specification variations across the used market mean that condition, configuration, and attachment history will influence how individual units are positioned relative to this average.
