One of the key stations on the new Crossrail project is Farringdon Station, and a long-reach JCB JS220 supplied by Lynch Plant has been chosen to carry out the required excavations on the site.
As JCB explains:
"After consultation with Lynch Plant Hire – one of the main equipment rental companies working with the major contractors and equipment supplier for the Farringdon Station site – it was decided to use a JCB JS220 long reach excavator which when fitted with an 8.7 metre boom and 6.4 metre dipper has a maximum dig depth of 11,990mm and a maximum reach of 15,600mm. The better the reach, the more ramp material can be removed, reducing the work of a smaller excavator operating at the lower level.
Power for the JS 220 is supplied by an Isuzu 4HK1X Tier 3 emissions compliant engine producing 128kW (172hp) at 2000rpm. JCB has, however just launched a brand new JS220 model at Bauma 2013, which is the first JCB excavator above 20 tonnes operating weight to adopt the company’s highly-efficient Ecomax diesel engine. It will result in Tier 4i compliance, a 10 per cent cut in fuel consumption and improved engine responsiveness without the need for a diesel particulate filter (DPF).
All equipment on the Crossrail contract has to comply with strict engine emissions noise regulations and dust pollution, which on the JS220 meant the retro-fitting of a DPF. The machine is also fitted with a simple red/green light cab mounted emissions monitor, which alerts the driver should emissions be too high."
