JCB has announced a series of major changes to its 23-strong range of tracked and wheeled excavators with the unveiling of a line-up promising to be more “stylish, productive and more efficient machines”.
In, what it is calling a ground-breaking move, some of JCB’s excavators are being powered by JCB Dieselmax engines for the first time ever – and in some cases deliver a staggering 24% improvement in fuel efficiency.
In addition all 19 tracked and four wheeled models from 11 to 46 tonnes get a brand new cab and also take on a new look, a restyle which gives the JS range a stronger more rugged appearance.
Typically the emerging markets tend to get left behind when new engine tech comes out of the OEM workshops, but JCB, which has a strong presence in China, India and several other developing markets, is fitting a Tier 2 variant into its 20-24 tonne ranges.
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. Today JCB also announces that the 4.8 litre Stage 2/Tier 2 JCB Dieselmax engine will power all 20–22 tonnes JS excavators destined for these markets.
The model numbers are: the 20 tonne JS200 the 21 tonne JS210 the 22 tonne JS220
While engine power rating remains at 128Kw or 172hp, 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.
