Road Grinding Machine

Abstract

A ridge in a lane of a roadway is ground away by providing a transverse beam carried on the support arms of a transport vehicle across a front of the vehicle, locating the vehicle longitudinally of the lane with the beam extending across the roadway and with the beam located by the vehicle in fixed position parallel to and above the ridge, moving a grinding assembly carried on the beam along the beam for grinding the ridge. The beam carries a gauge for a depth of grinding. The grinding assembly includes a toothed grinder rotatable about an axis transverse to the beam with a width transverse to the beam which is approximately equal to the width of the ridge.

1 . Apparatus for grinding a ridge in a lane of a roadway comprising:
 a support assembly for attachment to support arms of a transport vehicle;   a transverse beam carried on the support arms so that the transverse beam extends across a front of the vehicle whereby, with the vehicle standing longitudinally of the lane, the beam extends across the roadway;   and a grinding assembly carried on the beam so as to be movable along the beam for grinding the ridge;   whereby, with the beam located by the vehicle in fixed position parallel to and above the ridge, the grinding assembly moves along the beam to grind the ridge.   
     
     
         2 . The apparatus according to  claim 1  wherein the beam carries ground engaging elements for locating a height of the beam above the ground so as to provide a gauge for a depth of grinding. 
     
     
         3 . The apparatus according to  claim 1  wherein the grinding assembly includes a rotary member with an outer surface for engaging the ridge, the rotary member being rotatable about an axis transverse to the beam. 
     
     
         4 . The apparatus according to  claim 1  wherein the rotary member has a series of grinding teeth. 
     
     
         5 . The apparatus according to  claim 1  wherein the grinding member has a width transverse to the beam which is approximately equal to the width of the ridge. 
     
     
         6 . A method for grinding a ridge in a lane of a roadway comprising:
 providing a support assembly attached to support arms of a transport vehicle;   providing a transverse beam carried on the support arms so that the transverse beam extends across a front of the vehicle;   locating the vehicle standing longitudinally of the lane with the beam extending across the roadway;   with the beam located by the vehicle in fixed position parallel to and above the ridge, moving a grinding assembly carried on the beam along the beam for grinding the ridge.   
     
     
         7 . The method according to  claim 6  wherein the beam carries ground engaging elements for locating a height of the beam above the ground so as to provide a gauge for a depth of grinding. 
     
     
         8 . The method according to  claim 6  wherein the grinding assembly includes a rotary member with an outer surface for engaging the ridge, the rotary member being rotatable about an axis transverse to the beam. 
     
     
         9 . The method according to  claim 6  wherein the rotary member has a series of grinding teeth. 
     
     
         10 . The method according to  claim 6  wherein the grinding member has a width transverse to the beam which is approximately equal to the width of the ridge.
