Atlas Copco last week introduced a new generation of handheld hydraulic breakers with improved vibration characteristics in its 40- to 90-pound class of breakers. Atlas Copco engineers made these improvements by suspending the heavy spring-mounted handles in a dampened pivot pin, thereby decreasing vibration emissions.
“By incorporating an already successful and highly efficient vibration dampening handles from our line of TEX PE pneumatic breakers, we have achieved higher operator comfort on our hydraulic line of handheld breakers as well,” said Eudes Defoe, product manager handheld equipment. “Often vibro-reduction is achieved by reducing performance. Atlas Copco breakers maintain the same high performance level, but reduce vibrations significantly.”
Atlas Copco handheld hydraulic breakers were developed for concrete, asphalt and frozen ground applications, as well as for trenching, tie-tamping, spike driving and general demolition jobs.
At the show, the company also introduced its all-new XATS 1050 CD7 compressor. Replacing the XATS 950, the XATS 1050 CD7 features a new engine, air-end, cooling fan and controller.
The engine in the Atlas Copco XATS 1050 CD7 complies with the new Tier 4A emission standards that went into effect in the U.S., Canada, Japan and Europe in January 2011.
The new air-end in the XATS 1050CD7 is designed to operate more efficiently than its predecessors. Preliminary testing of the new model indicates that it will significantly reduce fuel consumption. Fuel economy is also improved by the variable-speed cooling fan, which is designed to run only as needed rather than continually.
Emission control is built in to the new controller. Unlike some other units, no separate control area is necessary.
