-strict regulations, the Rock Buster enable your work to be accomplished with Low-vibration, Low-noise and minimum dust.
Design and Manufacture
The Design of the power-cylinder is simple and manufactured in the smallest number of its parts for minimizing the future running cost.
Also, the products is planned to work efficiently for splitting a reinforced concrete and various types of rocks (soft / medium-hard / hard)
Opertability and Interchangeability
The Rock buster is workable even in a narrow work-space for the man handled rock-splitting.

Basic Unit (Manhandled)

The basic operational set of the Rock buster is consist of a power-cylinder(s), a power-pack and a ※power source.
The splitting procedure by power cylinder is manhandled.
