Filling a need for a breaker attachment better matched to precise sub-classes of hydraulic carriers, the HB 3600 hydraulic breaker from Atlas Copco Constructions Tools offers a higher power-to-weight ratio and higher efficiency than similar weight breakers on the market.

At a service weight of 7,940 pounds, the HB 3600 is suitable for hydraulic carriers in the 35 to 63 metric ton weight class. The breaker accepts maximum hydraulic flow of 79 gallons per minute at 2,610 psi. Delivering an impact rate of up to 560 blows per minute, the HB 3600 is ideal for applications such as demolition, trenching, foundation work, tunneling, rock mining and secondary breaking.

By filling the gap among the breaker classes previously available, the HB 3600 helps to eliminate undersized or oversized compromises when it comes to breaker-carrier match. This also allows the new breaker to deliver up to 46-percent more impact energy per pound than the average breaker used within its carrier weight class.

The HB 3600 comes standard with Atlas Copco’s PowerAdapt, a system that automatically shuts down the breaker in the event that it receives excessive oil pressure from the carrier, then returns it to normal function once the overflow situation is corrected. Also standard on the HB 3600 is AutoControl, a monitoring system that allows the breaker to adapt its frequency and power output to match operating conditions. An energy recovery system prevents damage from piston recoil on extremely hard materials. To reduce excess vibration and noise, the HB 3600 comes equipped with the VibroSilenced damping system. Meanwhile, the HeliCoil thread insert tensioning screw system allows for optimal absorption of tension force within the breaker, even under maximum loads.

For prolonged service life, the HB 3600 features ContiLube II, an automatic lubrication system mounted directly on the breaker. Featuring a compact, self-priming pump, ContiLube II eliminates the need to manually grease the breaker before each use.

The HB 3600 uses a working tool with a diameter of 6.7 inches and working length up to 30.3 inches. Tool options include the moil point for multi-purpose use, the flat chisel for rock breaking and demolition, and the blunt tool for breaking rock, concrete and oversized material. To protect the customer’s equipment investment and help ensure consistent productivity, the HB 3600 is accompanied by the Atlas Copco’s optional ProCare customer service package.
