Striking new blows with hydraulic hammers

Queensland-based Capricorn Quarries is a family owned business with more than 50 years of combined experience in sandstone quarrying. 
The business is located in Stanwell, about 25km west of Rockhampton, at a quarry that holds more than one million cubic metres of quality dimension stone that is used for structural, decorative and landscaping purposes and is very similar in colour to Sydney sandstone. Aside from the Stanwell quarry, Capricorn has also developed quarries in New South Wales and Western Australia.

The business provides Capricorn Buff and Heritage Rose sandstone for restoration projects across Australia and exports Brown Banded and Q8 sandstone to China for commercial and residential projects. Capricorn’s product has been used in prominent buildings in Rockhampton, while its Heritage Rose sandstone has been employed in the restoration of Queensland’s Parliament House in Brisbane. 

In and around Sydney, many landmark buildings incorporate Capricorn sandstone, including the Citibank building, Energy Australia’s Darling Harbour headquarters, the Sydney Domain Bridge and Sydney University.

The company has received numerous awards in recent years, including the 2011 Central Queensland Exporter of the Year, the 2010 Premier of Queensland (Tom Burns) Export Award, the 2010 Trade Queensland Emerging Exporter of the Year Award and the 2009 Main Chairman’s Industry Award.

Since 2006, Capricorn Quarries has employed 25- and 45-tonne excavators with rocksaws, jackhammers and rockgrabs to cut stone blocks from the Stanwell quarry’s reserve. It has capped this off by recently purchasing the Sandvik Rammer 2577 breaker from Precisionscreen, which is the authorised Rammer dealer for Queensland. 

The Rammer 2577 works with the existing Rammer BR2265 on a daily basis, breaking sections of sandstone into blocks and also carrying out larger boulder breaking applications on-site.

FIXED BLOW ENERGY
Rammer 2577 hydraulic hammers are suitable for carriers in the 21- to 30-tonne range. The 1700kg hammer has an impact rate of 450 to 750 blows per minute and features Rammer’s fixed blow energy (FBE) operating principle, which ensures optimum impact energy with every blow, regardless of hydraulic flow fluctuations. 

The twin-handed hammer’s features include a membrane-type accumulator, sound suppression, FBE, VIDAT tie rods and a range of options including the Ramlube I and Ramlube II, safety valve, idle blow protector and soft blow sensor.

Rammer breakers are ideal for primary demolition, boulder breaking, trenching and tunnelling.

The Rammer 2577 also has extras such as the Ramona monitoring analyser and the Ramair air flush system.

The Ramona monitoring analyser is used to analyse hammer operation and performance. The system stores statistical information for further analysis and warns and guides the operator for better operating habits. Ramona instrumentation consists of the analysis unit, transmitter and Ramcom software, and can be accessed by modem via SMS text messaging, computer or direct cable connection.

The Ramair air flush system is designed to prevent dirt from entering the hammer housing and keep the tool grease flowing towards the lower tool bushing. It is most beneficial in applications where material is highly abrasive and dusty. Ramair is also recommended for applications where the hammer working position is horizontal or above, such as tunnelling and scaling applications.

Capricorn Quarries owner Reece Gough’s decision to go with Rammer has been vindicated, given the current BR2265’s strong power and productivity capabilities influenced his decision. Gough is also impressed with the new Ramlube II auto-greasing system, saying it “makes the hammer easy to maintain, improves productivity and is extremely cost-efficient”. He added he was “very happy with Precisionscreen’s local dealer support”.
