A TWO-MAN cab is fitted to the JZ140 rail excavator which JCB launched in May. Adapted for rail use by Philmor Rail, the excavator weighs 21 tonnes in rail mode. The zero tail-swing design is suitable for use where a conventionally-profiled excavator would obstruct adjacent tracks.

A 2·1m dipper is fitted as standard, and a two-piece boom can be supplied to give a maximum dig depth of 5350mm. A hydraulic hand pump is fitted for emergency boom, dipper and slew recovery.

Four 500mm rail wheels are fitted to four hydrostatic motors, and a purpose-built trailer can be used to transport materials at a worksite. The JZ140 has automatic lighting on the chassis, a trailer breakaway alarm and the ability to travel under live overhead wires.

Options available include adaptation for use on underground metro lines, slew limiting for working under live wires, and a train air brake giving a towing capacity of 100 tonnes.
