History of the excavator hydraulic hammer

Hydraulic breakers are the oldest hydraulic attachments for carriers. The first serial manufactured rock breaker was the Krupp HM 400 in 1967 and the patent was secured in 1963. Excavator jack hammers are impact devices designed to break any kind of rock or concrete with any hardness or physical property. They have a wide range of applications such as demolition, deconstruction, primary rock excavation, secondary rock breaking, trenching, foundation work, asphalt cutting and many others.

Today Epirocs excavator hydraulic hammers are available from ~ 50 kg to more than 10,000 kg of operating weight for any kind of carrier. Over sixty years of development of the breaker hammers has produced advances at different levels, such as self-lubricating systems, sound & vibration damped systems, automatic rock hardness adjusting systems, energy recovery, solid body concept and much more.
