More stable: The traditional ripper adopts an embedded structure.In the process of excavating the crushed rock,failures such as the bolt falling off are prone to occur,which disperses the excavation power.The Combined Rock Arm adopts a integral ripper structure to educe the risk of additional failures,with stable cohesion and longer service life.

More flexible:The bucket oil cylinder is independently pressurized,and the construction cut-in angle of the Combined Rock Arm is increased by 307,which is convenient for the operator to find the weak point of the rock and break it,and excavate the earth more easily.
