A reliable choice for demolishing light concrete structures and asphalt pavements, both outdoors and indoors, the Solid Body (SB) concept for hydraulic breakers was introduced by Epiroc Tools & Attachments in 1993. The breakers use a patented internal component design that integrates the percussion mechanism and the guide system into a single piece. This, says the company, gives SB breakers outstanding durability.
Due to maintenance-free high-pressure accumulators, SB breakers offer blow frequencies from 550 up to 2.300 blows per minute. The compact design of SB hydraulic breakers allows them to be used with a smaller excavator, which the manufacturer says will help reduce carrier fuel consumption.
In addition to demolition tasks, the breakers are also suitable for performing earthworks, post driving, scaling in underground operations, cleaning ladles and converters in foundries, and other demanding tasks.
The breakers are designed for carriers in weight classes up to 24t, and are available in nine models with service weights ranging from 55 kg to 1,060 kg. The range includes models to match any micro or mini excavator, backhoe, skid steer loader or demolition robot.
The company’s SB 152-SB 1102 comes with integrated water nozzles as an option for dust suppression. With these nozzles, located in the front of the hydraulic breaker, dust is suppressed where it is created. A clear view and lower dust level is the advantage for people working at or living next to jobsites.
The hydraulic breakers in the series do not require special tools or adaptor fittings for installation, and the floating lower bushing can be replaced by the operator on-site with standard hand tools. Overload protection is provided by an integrated pressure relief valve. Also available are AutoStart, an air inlet for underwater applications, and Epiroc ContiLube II micro or ContiLube II automatic lubrication systems are optional on certain models.
