The machine replaces a JS220 and has been purchased to meet a growing requirement for heavier equipment and an increasing workload. The company has ordered the machine, its largest JCB excavator to date, with a triple articulating boom (TAB), adding to the versatility and flexibility of the JS260XD.
With a length of 6.24m, the TAB boom is longer than the standard 5.85m monoboom, providing an increased digging depth of up to 12.12m with a 3.53m dipper arm and a digging reach at ground level of as much as 11.13m. This additional length also provides improved access for high-reach work with a range of demolition attachments.
However the articulating boom also allows the operator to work right up to the tracks, particularly useful when operating with a grab or shear and handling demolition waste. This ability to vary the excavator's working envelope using the articulating boom, provides the operator with increased versatility and flexibility, particularly when working in confined operating conditions. The JS260XD is equipped with a full array of auxiliary piping, providing Sutton with a machine that can be used with hydraulic breakers, pulverisers, shears and grapples.

The excavator's quick hitch has been converted to work with the firm’s existing buckets and attachments and the additional weight of the XD machine, up to more than 27 tonnes, delivers a stable base for a range of demolition and recycling attachments. The TAB boom retains the powerful breakout forces of the standard machine, with dipper tearout of up to 18,272kgf and a bucket tearout of 19,574kgf.
The JS260XD has gone straight to work at the nearby RAF Mildenhall air base, where it is being used to demolish an accommodation block known as Building 479, for base facilities management provider Vinci Facilities. Sutton has a number of demolition projects ongoing for Vinci and has found the JS260XD to be better equipped to handle the two and three-storey buildings.
The JS260XD is powered by a Tier 4 Interim/Stage IIIB compliant four-cylinder diesel engine, delivering 188hp (140kW). This drives through a proven twin pump, variable flow, load-sensing hydraulic system, with flow on demand and variable output. JCB’s Smart Control System provides easy access to variable working modes with manual selection of High Plus mode for 100% productivity.
