The thorough work of perfecting the proven SB breaker concept for underground applications led to the introduction of SB 302 and SB 452 Tunnel version in 2017. With features focused on extended lifetime and overall cost reductions, they became an underground hit. Mid 2020 the family will double in size. Both the lighter SB 202, weighing in at 200 kg, and the powerful SB 552, with a service weight of 560 kg, will share the popular and robust qualities of the existing models. This also extends the scope of suitable carriers to 2.5-15 tons, previously 4.5-13 tons.

Among the application-specific modifications are the exchangeable wear plate and the front shield dust cover that extends lifetime by preventing bigger rocks from damaging the body and keeping dust out. Primarily important when working on overhead areas. The tunnel version is also equipped with integrated nozzles for water spraying, a feature with a positive effect on both health and safety. As the water catches the dust, the line of sight for the operator stays clear and the dust is kept on the ground. Bushing bore wear is kept down with a press-fit bushing locked by an additional pin. Exchangeable restrictors make sure performance is adjusted to the current job requirements, whether it’s traditional scaling or heavier rock breaking.

The DNA of the Solid Body concept is obvious in this advanced special version. Among the appreciated features carried over from the original SB breaker are the energy recovery system that uses recoil energy from the piston to reduce vibrations and increase performance, the pressure relief valve to protect against overload, and not the least all the weight, design, and durability benefits of the solid body itself.

“We’re pleased to provide all our customers working underground with further options. Their business is our number one priority and with the durability and low operating cost of these breakers we know we can support them even better”

concludes Torsten Ahr, Vice President Marketing.
