Hitachi EX1900-6 boosts productivity at Swinden Quarry

摘要

Tarmac's Swinden Quarry in the heart of the Yorkshire Dales National Park is one of the largest quarries in the north of England, and among the latest investments at the site is a Hitachi EX1900-6 ultra-large excavator. Delivered by Hitachi Construction Machinery (UK], the machine was built on site late last year. As the quarry's prime mover, the EX1900-6 is used to load up to 1,200 tonnes/h of Carboniferous limestone directly into a 200-tonne mobile crusher, playing a key role in maintaining the site's current production levels and annual output of 2.3 million tonnes.
