G&G Ross – New Hitachi 490 from TBF Thompson


When a County Antrim quarry business needed to replace an ageing excavator it was in a bit of a dilemma as to which brand to choose. Chris McCullough travelled to Ballycastle to find out why Hitachi emerged victorious.

Running a successful quarry takes a lot of organisational skills, a dedicated team of staff, customers, and of course, reliable equipment. Since 2002 the Ross family have owned Ballycastle Quarry in County Antrim situated between Armoy and Ballycastle and run it under the company name G&G Ross. Extending to 32 acres the quarry is a hive of activity every day supplying stones to local farmers, builders, construction companies and many more.

One of the most important tasks in the quarry for a machine is powering the rock breaker which ensures a constant supply of material for customers. For the past six years the quarry has relied on a 2007 Hitachi 520 excavator, that was initially purchased second hand, as its main machine on the rock breaker but with 16,500 hours on the clock the quarry owners decided it was time to retire it and upgrade to a new model.

Quarry co-owner and operations manager Graham Ross explained the rationale behind the decision to upgrade the Hitachi. “We ran a 2007 Hitachi 520 that was actually imported from Iceland at the time of the major economic crash there,” he says. “When we purchased the 520 second hand in 2012 it had only 4,000 hours on the clock. Over the years it had accumulated 16,500 hours so it was ready for replacing.”

Difficult decision

Graham also owns G&G Ross mobile stone crushing which runs Cat and Volvo excavators so he was somewhat torn between the brands as to which one to choose for the quarry. The quarry, too, has a number of brands working within it.

“The dilemma I had was what to replace the Hitachi 520 with,” he explains. “We also use Cat and Volvo machines as well so the pressure was on as to which brand to choose. That older Hitachi never gave us any trouble at all
and was very reliable indeed. It was for this reason as well as having decent fuel economy and decent overall operational costs that encouraged us to go for a new 50 tonne Hitachi Zaxis 490LCH-6 supplied by TBF Thompson in Garvagh. We purchased the new Hitachi with a fixed service charge so we can keep absolute control of some of the running costs, which is a good advan- tage.”


The new Hitachi 490LCH is fitted with a Montabert V4500 rock breaker and is in use every single day.

Hitachi says the latest ZX490LCH-6 is a tough machine suitable for heavy duty work incorporating all the latest Zaxis-6 innovation and technologies. Lower fuel consumption rates, less emissions and a quieter cab are all benefits
of owning this big Hitachi, which is powered by
a six cylinder, four-cycle water-cooled, common rail direct injection Isuzu AQ-6UZ1X engine rated at 270kW. The ZX490LCH-6 also produces fewer pollutants thanks to the variable geometry turbocharger and high volume-cooled exhaust gas recirculation system.

The boom has been reinforced with thicker plates, and the undercarriage consists of robust components including the track link, master pin, idler pedestal and bracket, and upper roller bracket. Sitting at just over 3.5m in height, the Hitachi ZX490LCH-6 is available with a couple of boom and arm options. It has a maximum digging reach of 12m and a maximum digging depth of 7.7m.

Jaron Davis is the manager at Ballycastle Quarry and says the new Hitachi is impressing everyone so far. “We got the new Hitachi just before Christmas and have put 260 hours on the clock so far,” he says. “I personally rate Hitachi equipment much better than both Cat and Volvo as demonstrated by the older Hitachi 520 that we replaced. In all its time working here, the
520 only needed a drive coupling fitted. It was a superb excavator and it was the good reputation of that machine that influenced the decision to buy another Hitachi.

“The new Hitachi ZX490LCH-6 is performing well,” adds Jaron. “It is very powerful and very smooth to operate. The superior cab provides a very quiet environment for the operator to work from.”

Breaking rock

The big Hitachi works well with the Montabert V4500 rock breaker but Jaron says it could handle a larger attachment. “The current rock breaker works well but with all that power the Hitachi has it could certainly handle a larger one,” he con- firms. “Having the service charge included in the deal is an added benefit from our point of view as we can leave that all to TBF Thompson. So far we are well pleased with the excavator and trust that it will operate as well and give as good a service as the previous Hitachi 520 did.”
