Medium range breakers
Sandvik’s Medium range of hydraulic breakers incorporates pistons and tools perfectly matched to ensure maximum energy transfer for optimum power and breaking efficiency. All the Medium range breakers come with a factory-installed RD3 device for intelligent fleet management and processes.
Medium range breakers have been designed to get into places where other breakers of their size can’t, featuring slim, robust housing made entirely of wear-resistant steel and a replaceable bottom plate.
Sandvik Medium range hydraulic breakers have constant productivity and are extremely reliable, while operating costs are low. The installation has been designed to be easy and safe for the operator, and the maintenance process is kept as simple as possible. The Medium range breakers are compatible with carriers from 10 to 32 tons.
