JCB CALLED on the experience of two demolition specialists - CDC Demolition and John F Hunt - in the development of two heavy-duty machines, the JS220 Xtra Duty and the JS260 Xtra Duty.
The machines are 360 degree excavators based on the 22-tonne JS220 and 26-tonne JS260 mainframes, but with additional protection and heavy duty dipper. The excavators have merged hydraulic circuits, which allow switching between high-demand crushers and the less demanding breakers.
CDC Demolition and John F Hunt bought the first two machines.
CDC's David Clarke said: 'JCB made a conscious effort to produce exactly what the demolition industry requires and I believe they have been successful. The JS220XD is powerful, well protected and extremely comfortable to operate.'
Two JCB 803 mini-excavators were used by contractor Doyle Demolition to lower the top four floors of six Birmingham tower blocks, which were out of reach of the wrecking ball. The machines were used to demolish the top of the lift shaft, then the floors were dismantled, with the rubble disposed of by dropping it down the shaft to ground level.
