Elfie's Plant Hire owner David Alford has been contracted by BORAL for approximately 10 years for secondary breaking requirements at their Colac Quarry. Here they use two Indeco Whisper breakers, an HP 5000 and an HP 9000, on which David has been testing the new ABF (Anti-Blank Firing) system and range of retaining axles in secondary breaking applications.
The word “porfido” (Italian for porphyry) conjures up pictures of Trentino-Alto Adige, where the stone has been quarried and cut for centuries. And there in Italy’s northernmost region, Quarry and Construction visited a quarry just outside Albiano, to see how an Indeco HP 5000 deals with porphyry.
The setting was the basalt quarry at the Northern Quarries site in Epping, Victoria, which for 12 years has been producing concrete aggregates and Class 1, 2 and 3 crushed rock for roads construction.
Indeco have designed, manufactured and installed a Hydraulic Power Pack, Arm Assembly and Breaker for Hanson Quarry, Hobart, Tasmania.
