JCB Present their Intermat innovations at a special event in La Manga, Spain - page 4 of 4




The largest market segment for excavators is in the 20-24 tonne weight range, accounting for just over one-third of all machines sold. A total of 80% of these are used in the developing economies, which are not subject to the more stringent US or European engine emissions legislation. JCB has also announced that the 4.8 litre Stage 2/Tier 2 JCB Dieselmax engine will power all 20–22 tonnes JS excavators destined for these markets.

While engine power rating remains at 128 Kw (172 hp), JCB has made a number of key changes, in particular incorporating new advanced hydraulic technology, with optimised pump settings and revised spool configuration. JCB has also modified the Advanced Management System to ensure that the excavator defaults to Economy mode on start-up.

Because of the incorporation of the same advanced hydraulic technology on Tier 2 machines fuel efficiency improves by 11% on each of these Tier 3 models with no engine modification. So, a British customer working a JS200 for 1,500 hours per year will save £2,750 compared with the previous model.

First JS Excavators with Tier IV Engines

Fuel efficiency on the new Tier 4 interim JS240 (24 tonnes), JS260 (26 tonnes), JS330 (33 tonnes) and JS360 (36 tonnes) improves by 8%.

These are the first JS models to move up to Stage 3B/Tier 4 Interim compliance.

Tier 4i compliance has been achieved by using Isuzu engines and by incorporating a variable geometry turbocharger, exhaust gas recirculation and a diesel particulate filter.

New cab across the range

JCB is introducing a new cab across its range of JS excavators and among one of the most important changes is on the front windscreen with the split between the top section and bottom section of glass now 125 mm lower in response to customer feedback. It’s now a 70/30 split, providing the operator with much improved visibility of the digging area.

A positive seal has also been created between the top and bottom sections, resulting in zero dust ingress into the cab. The bottom section of glass can be removed easily and conveniently stored within the rear window stowage area, again improving visibility to the digging area.

The front upper corner of the cab has been shifted forwards to accommodate a flat glass panel, instead of curved glass. This makes replacement much easier and less costly. Both the upper and lower sections of glass are laminated for additional protection and scratch resistance, as is the new roof glazing, which was previously polycarbonate.

JCB’s new cab also focuses heavily on the structure, which is becoming increasingly important for customers,   JCB’s new cab also focuses heavily on the structure, which is becoming increasingly important for customers, in particular Roll Over Protection (ROPS). While legislation doesn’t currently make ROPS mandatory, JCB is making ROPS protection available on all JS excavators.

For all models below 24 tonnes, ROPS will be integral to the cab – achieved through internal strengthening of the cab and machine structure. Externally, the ROPS cab will look the same as the non-ROPS cab, however a data plate inside the cab will highlight to the operator that it is the ROPS-protected version. For all models over 24 tonnes, a bolt-on ROPS cage will be fitted on to the machine.

Falling Objects Protection (FOPS) is equally important to JCB customers, particularly in the demolition sector and FOPS protection is available for all models for both front screen and roof screen. This can be factory-fitted or retro-fitted without the need to make any modifications to the cab structure
