A package of eleven Volvo articulated haulers and a seventy-five tonne EC750E mass excavator have re-established a long standing relationship between Hall Construction Services Ltd of Rushyford, Co Durham and Volvo Construction Equipment.
The EC750E along with six A40G articulated haulers, have gone to work on a five year overburden removal project to expose seams of high purity gypsum in an open cast mine on the outskirts of Newark in Nottinghamshire, where up to 2.8Mm³ of material is expected to be excavated each year.
A further five, slightly larger capacity Volvo A45Gs are on order to supplement the fleet on site which currently totals some twenty-eight items of mobile plant.
“We’ve had many years of experience operating Volvo products in applications ranging from bulk muck shifting to coal extraction particularly in the north east of England and Scotland,” says Managing Director, Stephen Hall. “Volvo has a strong support network throughout the country and this is important to us as we look to undertake nationwide projects such as this one in Newark.”
The latest G-series haulers from Volvo meet the requirements of Stage IV final emissions legislation being powered by electronically controlled, six-cylinder turbo charged Volvo V-ACT diesel engines. These feature high torque at low engine speeds, resulting in good fuel efficiency, high performance, quicker engine response and less wear.
With carrying capacities of 39 and 41 tonnes respectively, the A40G and A45G haulers can attain a maximum speed of 53kph for fast and productive cycle times. To maximise the volume capability of the trucks due to the friable nature of the overburden material on the Newark site, Hall Construction has added 300mm side extensions to the truck bodies, increasing the cubic metre capacity to handle five passes from a 5.7m³ bucket.
The new EC750E is a 75-tonne class crawler excavator that offers the perfect combination of power and stability to handle a higher capacity in any application. The EC750E features advanced fuel efficiency technology, ensuring an extremely responsive operation for maximum productivity and profitability. Powered by a Volvo 16-litre Stage IV diesel engine developing 508 nett hp, the EC750E offers innovative electro-hydraulic technology, delivering greater operator control and productivity.
Equipped in mass excavation configuration, the EC750E delivered to Hall Construction sports a 5.7m³ bucket fitted to the end of a 6.6m boom and a 2.9m dipper arm giving generous digging dimensions. For example, the machine’s forward reach measures 11.46m with a maximum digging depth of 7.21metres. The machine’s practical load over height is an impressive 7m and bucket breakout force 383kN in power max mode.
