Hitachi ZW310-5 wheeled loader
Norwegian producer of high-quality aggregates Hamar Pukk og Grus has invested in a new ZW310-5 for loading trucks and trailers at its 60-hectare quarry on the outskirts of the town of Hamar.
The wheeled loader is the first233 Hitachi machine in the company’s fleet and was delivered in April 2015 by the Norwegian dealer Nasta. It has joined a team of six personnel on the site, who are responsible for excavating 120,000m³ of materials and producing 250,000 tonnes of aggregates a year.
Material is loaded into a primary crusher to remove the sand that is then used for the production of concrete. A secondary crusher removes some of the larger stones which are sold as 20/120 for road and general construction site use. The remaining material goes through a third crusher to produce 0/4, 4/8, 8/11, 11/16 and 16/22 aggregates, which are used for roads, concrete, foundations and drainage work.
“We were able to test a larger model, the ZW330-5, beforehand thanks to Nasta and this helped us to make our decision,” said Rune Lund, general manager at Hamar Pukk og Grus.
“It has a high capacity for the loading process and it is especially effective at driving into the stockpiles,” said Technician Tore Bergrud, who has been working on the site for 27 years and driving wheeled loaders since 2005. “It is also easy to manoeuvre and very smooth for turning on full lock in a tight space. The Hitachi is also advantageous for load-and-carry operations and travels relatively quickly uphill compared to other larger machines.”
