Abstract

A roller-crusher comprising a boom (6) mounted on a vehicle body (3) and capable of rocking in a vertical direction, and an arm (8) mounted on the boom and capable of rocking in the vertical direction, wherein the boom and the arm are driven by a boom cylinder (7) and an arm cylinder (9), respectively. A hydraulic vibration generator (12) is fitted to the arm, and a breaker chisel (15) and a rolling member (16) are exchangeably fitted to the vibration generator. Further, a switch is disposed so as to bring the boom cylinder into the floating state during the rolling work.
