The first machines are being put to use on flood prevention schemes on Somerset Levels on behalf of the Environment Agency.
The JS145 long reach models have been purpose built, with the base machine of a conventional 14.5-tonne JCB excavator fitted with a long reach boom.
This combination of low operating weight and extra reach delivers better dredging ability.
Land & Water Director, Richard Maclean said: “We are proud to support British manufacturer and the technical expertise from the JCB factory is superb.
“The geometry of the arm is first class – providing good reach, excellent load over height and low transport position. We also like the fact that there is no diesel particulate filter, meaning the engines can be de-rated for export when the time comes to replace them.
“Operators like the cab environment which is light, spacious and very comfortable. We also particularly like the double safety isolating device.”
These new machines join six existing JCB excavators in the Land & Water fleet, which is largest fleet of specialist long reach excavators, dredging equipment and floating plant in the UK.
