Miller’s breaker
Miller's debut breaker range includes dual-speed control, auto-stop system, large accumulator and auto-lubrication as standard
Cutting-edge hydraulic breakers, drills and hammers are a feature of 2014, with the recent Steinexpo show hosting the launch of more new models. Guy Woodford reports.

Chicago Pneumatic’s hydraulic breakers and portable compressors are said to be proving a great fit for India’s expanding granite building stone industry.  An example of this is Kerala-based granite quarry National Granite and Hollow Bricks which is successfully using CP1150 and RX22 hydraulic breakers as well as a CPP60E portable air compressor to perform essential breaking and drilling operations.  

Founded in 1998 in the Kannur district of Kerala, in southern India, National Granite and Hollow Bricks currently employs 40 people and is a leading producer of granite building stone. Resistant to wear and tear as well as weathering, this material is currently in great demand across the construction industry, with India being one of the largest exporters of granite worldwide. As part of the quarrying process, the granite rocks resulting from primary blasting need to undergo secondary breaking to fit into the jaw crushers.

In order to effectively perform this operation, National Granite sought out Chicago Pneumatic’s breaking equipment. After a successful on-site demonstration, the company purchased its first CP1150 rig-mounted medium hydraulic breaker in 2006, followed by a RX22 a few years later.

“We are impressed by the toughness and reliability of Chicago Pneumatic hydraulic breakers, which are proving ideal for our quarrying operations,” says National Granite’s managing partner, Mohamed Nazeer adding:  “Having already clocked 10,000 and 5,000 hours respectively, our CP1150 and RX22 are helping us increase our quarry’s overall productivity with low maintenance costs.”

Said to be thanks to their innovative design, featuring limited components and only two moving parts, Chicago Pneumatic’s medium hydraulic breakers are built to ensure high reliability and endurance. Other key features include internal control valves for improved efficiency, a power booster for higher performance and a lower vibration and central lubrication port for easier maintenance. Furthermore, Chicago Pneumatic’s medium breaker range features dust wipers and ventilation ports for better dust protection, which make it ideal for quarrying and mining applications. 

Not only is Chicago Pneumatic’s construction equipment helping National Granite improve its breaking process, but also its primary drilling operations, which precede the blasting phase. In order to effectively power its drills to drill holes in the rocks, the quarry is currently relying on a CPP60E portable air compressor, which has already clocked 5,000 hours of reliable service. “This portable compressor is easy to operate and maintain as well as being reliable and tough”, says Nazeer, adding: “All these features makes this product a great fit for a very demanding application such as drilling granite.”

A single axle electric driven compressor, the CPP60E has been specifically designed by Chicago Pneumatic to provide compressed air to pneumatic tools such as rock drills and demolition tools. With low rotor speed and a few moving parts, this compressor ensures high reliability and long working life, by minimising wear and tear. In addition, its single high performance two-stage air intake filter prevents dust and dirt particles from entering the engine. Other key features include a user-friendly control panel and canopy doors opening outwards for easy access and maintenance.

The recent Steinexpo 2014 exhibition saw Sandvik Construction add a new radio remote-controlled drill rig to its surface top hammer drill rig offering. Said by the Swedish firm to be engineered to combine all the best features in one unit: drilling performance with premium hole quality, easy maintenance and excellent manoeuvrability, as well as attractive exterior, Sandvik Construction claim the Dino DC400Ri is ready to take the lead in surface drilling excellence.

Dino DC400Ri is a hydraulic, self-propelled, self-contained, crawler-based surface drilling unit with full radio remote control operation for 51–76mm holes. It is said to offer top drilling performance with a new RD414 rock drill, a robust boom said to have the largest coverage area of its size, a patented collaring guide and an economical Tier 4 Final engine. Due to its versatility, the Dino DC400Ri is said by Sandvik Construction to be the perfect machine for drilling and blasting contractors, but suitable also for quarries and the municipal sector. Its typical applications consist of road construction, demolition works, secondary breaking, foundation drilling and trenching.

The new, extremely fast RD414 rock drill by Sandvik Construction has been specially designed for the Dino DC400Ri. It is said to provide smooth penetration, yet is kind to the rock tools. A new patented collaring guide makes starting a hole easy and accurate even in inclined rock. The completely new boom, with a robust design and said to be the largest coverage area in its class, ensures perfect support for the feed during drilling, but also enables more drilling hours from one single setup. On top of this, the powerful tramming motors and low tramming height with its low centre of gravity, as well as full radio control for the entire rig, ensure that the Dino DC400Ri will respond with precision even in the most uneven terrain.

The Dino DC400Ri comes equipped with the latest fuel saving systems. These consist of electric load sensing, ambient controlled cooler fans, a hydraulic compressor control system that utilises the latest technology, optimised airlines and fuel efficient Tier 4 Final engine. All of these features combine to provide very low fuel consumption. Additionally, easy maintenance through ground level service points, onboard diagnostics and small transportation dimensions, are benefits resulting from the completely new drill rig layout.
