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
So far, 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,” comments Managing Director, Stephen Hall. “They have a sound pedigree in terms of reliability and performance, with good residuals. Equally, 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. These factors together with a competitive package on offer were the deciding factors on opting for the latest Volvo products,” Stephen says.
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, in other words, long service life. Purpose built by Volvo, the engine is designed to exactly match the Volvo drive train, ensuring the best use of power and torque, even in tough working conditions.
Delivering exceptional fuel efficiency, it is matched to a torque converter with built-in lock-up function and fitted with a fully automatic fast adaptive transmission. The rest of the Volvo designed and built powertrain has been reinforced to cope with the higher torque output of the engine.
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 haulers are also fitted with CareTrack as standard which is Volvo’s telematics system that enables remote monitoring of a wide range of machine functions (eg. location, fuel consumption, service reminders, etc) thereby optimizing customer operations.
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. Building on the successful legacy of the EC700 which was originally launched in 2005, 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.
Hall Construction Services Limited was established in 1986 by brothers Stephen and Neville Hall who continue to have an active role in the management of the business. The company, whilst working on projects throughout the United Kingdom, has maintained
