In addition to the top type hydraulic hammer, we also supply side type hydraulic rock breaker and box type rock breaker. All of them are highly efficient excavator jack hammers. The side type rock breaker offers distinct advantages when operating at a distance from the excavator. The installation point of the side type hydraulic breaker on the excavator’s arm is low, making it easy to lift, which is suitable for some demolition operations. The top type and box type hydraulic rock breaker has a larger direct acting force and has obvious advantages in vertically hitting stones and the like.
