Hitachi machines productive in West African quarry

Two Hitachi ZX350LCH-3Gs recently acquired by West African company Logistics Support Services (LSS) are proving invaluable assets to operations at the Arigu Rock quarry, located close to Tamale in northern Ghana. The medium Zaxis-3 excavators are working across the 18ha site to excavate granite materials for use in road construction and concrete works, among others.

Two 233 Hitachi ZX350LCH-3Gs recently acquired by West African company Logistics Support Services (LSS) are proving invaluable assets to operations at the Arigu Rock quarry, located close to Tamale in northern Ghana. The medium Zaxis-3 excavators are working across the 18ha site to excavate granite materials for use in road construction and concrete works, among others.

Acquired in early 2015 by LSS, the Arigu Rock quarry holds enough materials to sustain an operation for over 50 years. The site’s 24 employees work 16 hours a day in eight-hour shifts to supply aggregates to customers, such as Brazilian firms Queiroz Galvão and Andrade Gutierrez, as well as local businesses.
The ZX350LCH-3G excavators were supplied to LSS in May 2015 by authorised African Hitachi dealer DEM Group’s regional subsidiary, DEM Ghana. The two Hitachi excavators being used first for site clearance. Once the rock has been blasted, the ZX350LCH-3Gs are fitted with hydraulic hammers to carry out secondary breaking and are then equipped with buckets to load the rock, gravel and sand on to the site’s dump trucks and lorries.

The raw materials are then deposited into the primary crusher to be processed into various sizes of aggregates: 0-0.5mm, 0.5-10mm, 14mm, 20mm and 25mm. In total, the quarry produces 500m³ of materials/day.
