Abstract

A portable, mechanized scaling tool for the dislodging of unstable rocks from the walls of underground mine passageways comprising a telescopic handle from one to two meters in length and a tool point of innovative geometry having a longitudinal axis and two ends, an angular shank with another longitudinal axis, a length and two sides, an elongated S-shaped junction portion, an anvil with an elongated body and two ends intended to be axially displaced, and a means of periodic displacement acting on the anvil. The tool point generates a lever effect on the unstable rocks which results in their rapid dislodgment while minimizing the bending effort of the operator, facilitating the work and improving the safety of the operators and the work areas. The scaler is lightweight and ergonomically designed, adapting to the worker's natural position.
