Breaking efficiency and productivity barriers

Home Mining & Quarrying Breaking efficiency and productivity barriers

THE RTEX and TEX pneumatic breaker ranges from Atlas Copco are a perfect balance between great performance and high comfort.

That’s according to the company’s Power Technique division Business Line Manager of Portable Products, David Stanford, who said the latest RTEX medium breaker high breaking efficiency to a patented design featuring a constant pressure chamber which improves energy transfer, providing up to 40% more energy output than conventional units.

The machine also features a longer piston compared to conventional breakers, which increases the interaction time with each blow. The efficient stroke mechanism also radically lowers energy consumption.

As a result, said Stanford, the RTEX, weighing only 25 kg, has a breaking power that matches much heavier top class 30-35 kg breakers. “The RTEX can therefore do the same job equally well as the heavier machines while using only half as much compressed air.

“A 50% reduction in compressed air consumption for the same breaking capacity also means that a compressor only half the size is needed or two breakers can be used on one compressor which previously powered only one breaker. A smaller compressor requires a smaller investment, uses less fuel, has lower emissions and is easier to transport, delivering a return on investment that is second to none.”

Thanks to the solid or single body (SB) design, the RTEX and TEX breakers have a low centre of gravity and are well-balanced which make for simple, easy handling. Stanford said these one-piece machines have fewer parts and thus less moving components that can wear resulting in improved reliability, extended lifecycle and reduced maintenance time and costs.

The breakers’ unique two-step SOFTSTART trigger gives operators full control ensuring that the first cut is surgically precise with no chisel slippage or misfiring even under tough conditions. An integrated lubricator minimises tool wear and also holds enough lubricant for an entire normal work shift which boosts productivity.

Prolonged exposure to high vibrations and noise levels can result in operator fatigue which compromises safety and productivity. To counter this, Atlas Copco has HAPS (Hand and Arm Protection Systems) enabled its pneumatic breakers.

“An efficient stroke mechanism with a constant pressure chamber keep vibration levels below 5m/s², increasing operator comfort and making it possible to extend working hours up to six-fold.”

In addition, the tools’ piston switches on air cushions on both ends of the cylinder, almost fully eliminating metal-to-metal contact when working off-load, thereby further shrinking vibration and wear. The pneumatic breakers are also fitted with a wear-resistant polyurethane silencer that diminishes noise levels by up to 75% compared to a machine without a silencer.

“The TEX light and RTEX medium pneumatic breakers will make light work of service jobs and general demolition tasks.” The company’s TEX heavy pneumatic breakers are recommended for heavy-duty demolition work on material such as asphalt and reinforced concrete.
