Atlas Copco HB 4200.The HB 4200 hydraulic breaker breaker: see wave, in oceanography. features Krupp percussion percussion /per·cus·sion/ (per-kush´un) the act of striking a part with short, sharp blows as an aid in diagnosing the condition of the underlying parts by the sound obtained. technology and a service weight of more than 4 tons, making it ideal for demolition, tunneling, trenching, foundation work and quarry breaking. * The tool accepts a maximum hydraulic flow of 84 gallons per minute at 2,610 psi. * The HB 4200 breaker delivers an impact rate of up to 530 blows per minute. * Comes with AutoControl monitoring system. * Equipped with the VibroSilenced damping damping In physics, the restraint of vibratory motion, such as mechanical oscillations, noise, and alternating electric currents, by dissipating energy. Unless a child keeps pumping a swing, the back-and-forth motion decreases; damping by the air's friction opposes the system. Elastic elements between the percussion mechanism and the guide system provide full acoustic insulation, reducing noise by up to 18 decibels compared to similar systems. * For prolonged service life, the HB 4200 features DustProtector II and ContiLube II. The optional DustProtector II feature prevents dust penetration by using a reusable sleeve that contacts the working tool at the base of the breaker to protect the inner mechanism from the damaging effects of dust. The ContiLube II is an automatic lubrication lubrication, introduction of a substance between the contact surfaces of moving parts to reduce friction and to dissipate heat. A lubricant may be oil, grease, graphite, or any substance—gas, liquid, semisolid, or solid—that permits free action of system mounted directly on the breaker. * The HB 4200 is a working tool of 7.09 inches in diameter with working lengths of up to 40 inches. * Available in three lengths for various applications, the HB 4200 options include the moil point for multi-purpose use, the flat chisel a sculptor's chisel for smoothing. - Knight.
