Top Type Excavator Rock Breaker Hammer FURUKAWA HB15G 15-19 Ton Excavator Attachment
What is the difference between side type and top type hydraulic breakers?
For example, a side-type breaker is better for breaking concrete walls, while a top-type breaker is better for breaking apart large rocks. 3. Machine compatibility: Ensure that the hydraulic rock breaker is compatible with the carrier machine, such as an excavator or backhoe loader used for the job
How do I choose a rock breaker?
Choosing the right rock breaker for your project
To make the right choice, you need to know the types and sizes of the rocks you need to break and, most importantly, the size and capacity of your excavator. You need to ensure your equipment is strong enough to handle the job.
How does a rock hammer work?
It employs a high-pressure hydraulic system, which supplies hydraulic fluid to the rock breaker's cylinder. This fluid puts pressure on a piston, which, in turn, transfers the force to a tool shaft, usually a steel chisel. The repeated hammering action of the chisel into the rock or concrete breaks it apart
