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 ...

Purchasing a hydraulic breaker shouldn't be compared to buying a mattress. Understanding its internal components is entirely feasible. Although numerous factors come into play, one question commonly asked by contractors is the level of impact force a breaker can deliver, or more precisely, its power or impact energy.

Hydraulic systems allow for precise control of the breaker's impact force and frequency. This level of control is crucial when working in sensitive areas or when dealing with fragile structures. Pneumatic breakers, on the other hand, may lack the same level of control, making them less suitable for tasks that require precision.
