Acerca de · JCB 85Z-2Resumen
The JCB 85Z-2 is an 8.5-tonne zero-tail-swing mini-excavator, positioning it at the upper boundary of the compact excavator class where reduced-radius swing geometry allows operation in confined or obstruction-rich environments. Its zero-tail-swing design keeps the counterweight within the track width throughout a full 360-degree slew cycle, making it a specialist tool where conventional excavators of similar weight cannot safely operate. The machine belongs to JCB's second-generation compact excavator lineup and is built around a canopy or cab configuration depending on specification.
Aplicaciones típicasDónde se utiliza esta máquina
The 85Z-2 is suited to urban civil works, utility trenching, and foundation excavation in restricted sites where swing radius is a constraint rather than an afterthought. Landscaping contractors, groundworkers, and pipeline crews operating in congested residential or commercial environments regularly specify machines in this weight class. The upper end of the mini-excavator range also supports light demolition, bulk material handling with appropriate attachments, and site-preparation tasks that fall below the threshold requiring a conventional mid-size excavator.
Inspección del mercado de segunda manoQué hay que comprobar antes de comprar
Inspect the undercarriage carefully, as track frames, rollers, idlers, and rubber tracks represent a meaningful portion of reconditioning cost on any machine in this weight class. Check the slew ring and slew motor for play and smooth operation, since zero-tail-swing machines place particular rotational demand on those components in confined-site use. Examine all hydraulic lines, cylinders, and quick-connect couplings for weeping seals or surface corrosion, and operate the boom, dipper, and bucket through full range to confirm there is no drift under load. Confirm that the auxiliary hydraulic circuit, if fitted, delivers appropriate flow and pressure for the intended attachments. Request service records and cross-reference stated hours against physical wear indicators on the cab interior, controls, and seat. On cab-equipped units, check door seals, glass condition, and HVAC function. A pre-purchase inspection by an independent engineer familiar with this machine class is advisable before committing.

Within the 8 to 9-tonne zero-tail-swing segment, the JCB 85Z-2 is regularly cross-shopped against the Kubota KX080-4, the Volvo ECR88D, and the Yanmar SV100. The zero-tail-swing configuration distinguishes it from conventional-tail machines at the same operating weight, which typically offer greater counterweight mass and stability at the cost of swing-radius flexibility. Attributes that move a used 85Z-2 within its price band include recorded machine hours, the presence of a factory cab versus open canopy, auxiliary hydraulic configuration, the number and condition of any included attachments such as buckets or a quick-hitch, documented service history, track condition, and overall undercarriage wear. Machines with a full service record, low accumulated hours, and a proportioning auxiliary circuit command stronger positioning than equivalent-year units lacking documentation or carrying worn running gear.
