Excavator rock breaker RT 47

hydraulic

Description
RT 47 demolition hammer is designed for construction and renovation tasks where demolition of concrete or masonry is required, especially in confined or narrow work areas. The closed casing protects internal components from impacts, rocks and dust while contributing to noise reduction. The RT 47 is suitable for mounting on skid steer loaders and mini excavators and can be interchanged with other breakers via a skid steer plate.
