Abrading Device

Abstract

The invention concerns a device for abrading a wall of stone or concrete material. The invention comprises a shell ( 2 ) with which is operationally connected an abrading head ( 1 ), and a carriage intended to move at least along the surface and support the shell ( 2 ) movably so that the abrading head ( 1 ) by means of the movement of the shell ( 2 ) performs an upward and downward abrading movement. The abrading head ( 1 ) is of the type which has a rotatably mounted and driven planet wheel with a number of driven abrading discs rotatably mounted thereon and fitted with abrading elements. The device has an element for placing the abrading head ( 1 ) with a predeterminable force against the surface to be abraded.

1 . Device for abrading a wall of stone or concrete material, which comprises:
 a shell with which is operationally connected an abrading head, and a carriage intended for moving at least along the surface and supporting the shell moveably so that the abrading head by the movement of the shell performs an upward and downward abrading movement, the abrading head is of the type which has a rotatably mounted and driven planet wheel with a number of driven abrading discs rotatably mounted thereon and fitted with abrading elements, and an element for placing the abrading head with a predeterminable force against the surface to be abraded.   
   
   
       2 . Device according to  claim 1 , wherein said element for placing the abrading head comprises at least one gas spring or at least one hydraulic cylinder/piston device. 
   
   
       3 . Device according to  claim 1  wherein the operational connection comprises a universal mounting of the abrading head with a counterweight balancing this. 
   
   
       4 . Device according to  claim 1 , wherein the carriage is a forklift truck and the shell is intended to be mounted on the forks of the truck.
