Handheld pneumatic breakers lighter, safer and more precise

Home Infrastructure Construction & Civils Handheld pneumatic breakers lighter, safer and more precise

THE powerful, lightweight, and ergonomic RTEX and TEX pneumatic breaker ranges from Atlas Copco can be operated for longer while using less air.

That’s according to David Stanford, Business Line Manager, Portable Products, at Atlas Copco Power Technique, who said these tools offer the perfect balance between high performance, efficiency and comfort.

He said the RTEX medium breaker owes its “unparalleled” breaking efficiency to a number of cutting-edge design features that include a patented Constant Pressure Control principle, encompassing a Constant Pressure Chamber, which improves energy transfer, providing up to 40% more energy output than conventional units.

A longer piston design compared to conventional breakers increases the interaction time with each blow. The resultant efficient stroke mechanism also radically lowers energy consumption.

Subsequently, said Stanford, the RTEX, weighing only 25kg, can perform the same job equally well as bigger machines that are 5kg to 10kg heavier. The RTEX can also operate for longer while using only half as much compressed air.

“A 50% reduction in compressed air consumption for the same breaking capacity means that a compressor only half the size is needed or alternatively, two breakers can be used on one compressor,” he said.

“What customers must also keep in mind is that a smaller compressor requires a smaller investment, uses less fuel, has lower emissions and is easier to transport, subsequently delivering an excellent return on investment.”

He said productivity, low operational costs and operator comfort and safety are central to the design of the RTEX and TEX breakers. “A low centre of gravity and perfect balance, thanks to the ingenious Solid or Single Body (SB) design, make these one-piece machines extremely easy to handle. Fewer parts, and thus fewer moving components that can wear, improve reliability, extend lifecycle and reduce maintenance.”

Tool wear is further minimised by the integrated lubricator which holds enough lubricant for a complete standard work shift.

“The hand-held breaker’s innovative two-step SOFTSTART trigger puts operators in full control by ensuring that the first cut is surgically precise with no chisel slippage or misfiring, even under extremely tough conditions.”

To counter high vibration and noise levels which can result in operator fatigue, compromising safety and productivity, these pneumatic breakers are HAPS (Hand and Arm Protection Systems) enabled.

“The Constant Pressure Chamber and efficient stroke mechanism keep vibration levels below 5 m/s², enhancing operator comfort to such an extent that working hours can be extended up to six-fold.”

The tool’s piston switches on air cushions on both ends of the cylinder, almost fully eliminating metal-to-metal contact when working off-load, further shrinking vibration and wear, Stanford said.

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.

Stanford said the RTEX medium and TEX light pneumatic breakers are ideal for service jobs and general demolition tasks. The TEX range is also available in medium and heavy pneumatic models which are suitable for respectively breaking medium hard materials and for heavy-duty demolition work on asphalt and reinforced concrete.

Atlas Copco supports both pneumatic breaker ranges with Air Line accessories including air hoses, hose nipples, couplings, water separators and Air Oil lubricants, backed by an after-sales service.
