Acerca de · Kubota KX057Resumen
The Kubota KX057 is a conventional-tail-swing mini-excavator in the 5.5-tonne class, producing 47 hp and carrying a rated bucket capacity of 0.17 m3. With an operating weight of 5540 kg it sits at the upper boundary of the compact excavator segment, offering greater digging force and lift capacity than sub-5-tonne machines while remaining transportable on a standard trailer. The model has been in continuous production since 2009, meaning a broad range of build years and specification levels is available on the used market.
Aplicaciones típicasDónde se utiliza esta máquina
Machines in this weight and power class are routinely deployed on utility trenching, drainage installation, landscaping groundworks, and confined urban construction sites where a larger excavator cannot manoeuvre. The 0.17 m3 bucket suits general earthmoving, service-trench backfill, and foundation excavation on residential and light commercial projects. Contractors also use machines of this type for pipe-laying support, road reinstatement, and rural land-drainage work.
Inspección del mercado de segunda manoQué hay que comprobar antes de comprar
Inspect the undercarriage closely on any mini-excavator of this type: rubber tracks, rollers, and sprockets are high-wear items whose condition significantly affects near-term ownership cost. Check all hydraulic cylinders for seal leaks and verify smooth, responsive operation of the boom, arm, and bucket through their full range of motion. Examine the slew ring for play and unusual noise, and review any available service records to confirm oil and filter intervals have been maintained. Where auxiliary hydraulics are fitted, test flow and pressure at the coupler before purchase. On machines of this production vintage, corrosion in the lower frame sections and around the blade pivot points warrants close attention.

The KX057 competes directly with the JCB 57C-1 and the Bobcat E55, all three occupying the 5- to 6-tonne compact-excavator bracket. Against the JCB 57C-1, the KX057 shares a comparable power output but buyers typically compare cab ergonomics, dealer network density, and parts availability when choosing between them. The Bobcat E55 is a zero-tail-swing alternative in the same class, which makes it preferable on sites with tight lateral clearance, while the KX057 conventional-tail layout generally supports greater counterweight and stability during heavy lifts. Within the used segment, the primary drivers of where any individual KX057 sits in its pricing band are recorded working hours, overall mechanical and structural condition, the presence or absence of a quick-hitch, auxiliary hydraulic lines, the attachment inventory included in the sale, cab configuration, and whether full service history is documented. Machines with lower hours, recent undercarriage work, and a verified maintenance record command the stronger end of the range.
