Top hammer shank adaptors, the role of which in rock drilling is to directly bear the impact energy and torque of the rock drill, and is used to transfer the energy from drill rig to drill rod. One end of the shank adaptor is connected to drill rig, and another end is connected to drill rod, so that the energy of drill rig can be transmitted to drill bit, and finally achieve the purpose of drilling.

The specification and hardness of top hammer shank adaptor have a great influence on the rock drilling speed and the life of the rock drill. The hardness of the top hammer shank adaptors for drill should be appropriate, the service life is short if the rock drill shank is too soft, the piston is vulnerable to damage if the drill shank adapter is too hard. Litian shank adaptor factory has accurate specifications, smooth surface, suitable hardness, the cross-section is perpendicular to the axis, and closely coincides with rock drill sleeve.
