Atlas Copco has added the 1,654-pound MB 750 to its line of hydraulic breakers. Specified for machines in the 10- to 17-ton range, the breaker operates under 2,030 to 2,465 psi and delivers 370 to 800 blows per minute. The tool diameter is 3.9 inches. Double retainer bar system and DustProtector II maximize service life, the company says. VibroSilenced system acoustically isolates the percussion mechanism from the external guide system, giving the breaker a noise level of 118 decibels.
