According to Sandvik, its growing RH460 family optimizes impact-energy transmission in variable ground conditions. Enhanced air cycle improves expansion and compression rates, producing more power while reducing air and fuel consumption. Developments in piston design and improved lubrication capabilities increase piston and hammer life across the RH460 series. Sandvik said it has devoted significant R&D work into designing the bearing surfaces to ensure bending vibrations in the piston are eliminated. RH460 hammers also feature a unique V-lock mount system designed to prevent movement of the internal components, ensuring reliability and eliminating the need for shims and special assembly tools.

The working principle of the RH460 range ensures that the hammers start up in any direction, making their design useful for all surface and underground mining applications; and, said Sandvik, the design of the RH460 series makes the hammers easy to service. The entire range is designed to utilize bits with generic shank types.
