Excavator Size Classes & Compatible Models

Excavators are generally grouped into four size classes by operating weight: mini/compact (0–6 metric tons), midi (6–12 metric tons), standard/full-size (12–45 metric tons), and large (45+ metric tons). The OSA GR15 is built for the standard/full-size class, in the 20–29 metric ton range — the same weight class as the Caterpillar 320, which the included mounting bracket is sized for.

Comparable excavators in this weight class from other major manufacturers include:

• Caterpillar: 320, 321, 322, 323, 324
• Komatsu: PC210, PC220, PC228USLC
• Volvo: EC220D/E, EC250E
• John Deere: 210G LC, 245G LC
• Case: CX210D, CX225D, CX250D
• Hyundai: HX220L, HX260L
• Hitachi: ZX210LC, ZX225USLC, ZX250LC

• Doosan / DEVELON: DX225LC, DX235LC, DX255LC
• Link-Belt: 210 X4, 220 X, 250 X4

Always confirm your excavator's auxiliary hydraulic flow, operating pressure, and coupler/pin dimensions match this attachment before ordering.
