Hydraulic Breaker has 3 main types:
1. Side Type Hydraulic Breaker: Versatile appliPCion including rock broken, paving road, building demolition etc.
2. Silenced Hydraulic Breaker: Low noise, saving energy and protecting environment.
3. Top Type Hydraulic Breaker: Applied to special operation thatin large elevation angle.
What is the difference among side type,box type and top type rock breakers?
For Side type, the installation pins are on the side of the breaker.
For Top type , the installation pins are on the top of the rock breaker.
For box type, the rock breaker bracket is full sealed like a box,and it equiped with rubber cushion inside of the bracket to keep lower noise. So it is also called silence type rock breaker.The installation pins are also on the top for silent type rock breaker, same as top type installation way on the excavtors. Both side type and top type breakers are with opening bracket, which is easy for maintenance and parts exchanging. But for box type rock breaker, it has to open the box and move out the main body to do maintenance job.
