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.

width of the ridge.
Description
[0001] This application claims the benefit of priority under 35 USC
119(e) of Provisional Application 61/445,368 filed Feb. 22
2011.
[0002] This invention relates to a road grinding machine.
BACKGROUND OF THE INVENTION
[0003] Many roads particularly in cold environments develop
transverse ridges in the asphalt which cross the pavement at spaced
positions along the direction of travel. These cause severe
undulations of travelling vehicles due to the periodic nature of
the ridges and are a considerable source of discomfort for
occupants. Up to now there has been no suitable dedicated machine
for quickly and easily removing these ridges so that they need to
be ground off by conventional machinery grinding the whole pavement
or moved back and forth over the pavement.
SUMMARY OF THE INVENTION
[0004] It is one object of the invention to provide a suitable
dedicated machine for quickly and easily removing these ridges.
[0005] According to one aspect of the invention there is provided
an apparatus for grinding a ridge in a lane of a roadway
comprising:
[0006] a support assembly for attachment to support arms of a
transport vehicle;
[0007] 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;
[0008] 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.
[0009] Preferably the beam carries ground engaging elements for
locating a height of the beam above the ground whereby the gauge a
depth of grinding.
[0010] Preferably 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.
[0011] Preferably the rotary member has a series of grinding
teeth.
[0012] Preferably the grinding member has width transverse to the
beam which is approximately equal to the width of the ridge.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] One embodiment of the invention will now be described in
conjunction with the accompanying drawings in which:
[0014] FIG. 1 is a schematic top plan view of an apparatus
according to the present invention.
[0015] FIG. 2 is a front elevational view of the apparatus of FIG.
1.

corresponding parts in the different figures.
DETAILED DESCRIPTION
[0017] The apparatus for grinding a ridge 16 in a lane 18 of a
roadway 17 includes a support assembly 10 designed for attachment
to support arms 12, 13 of a transport vehicle 14. The vehicle can
be of the type such as a skid steer loader or back hoe or other
commercial tractor which includes front lift arms which can be
operated using tractor controls. The support 10 is designed to
allow the apparatus to mount on the arms for movement by the arms,
with the design be arranged to match the connections of the arms as
is known to a person skilled in the art. The lane 18 is defined by
side lines 18A.
[0018] A transverse beam 11 is 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 to or slightly beyond the ends 18A.
[0019] A grinding assembly 20 is carried on the beam by a guide
mounting 21 so as to be movable along the beam 11 driven by a drive
motor 22. Thus the mounting 21 can form a sleeve mounted on
suitable bearings which allows free movement along the beam between
the ends of the beam by-passing the support 10. The grinding
assembly is arranged for grinding the ridge 16 with the beam
located by the vehicle in fixed position parallel to and above the
ridge. Thus the grinding assembly 20 moves along the beam to grind
the ridge back down to the level of the roadway 17.
[0020] The beam carries ground engaging elements 27 engaging the
roadway 17 for locating a height of the beam above the ground so as
to gauge a depth of grinding down to the roadway 17 but no deeper.
Thus the grinding assembly is at a constant height on the beam as
it operates so that the height of the beam above the roadway 17
remains fixed with the vehicle stationary.
[0021] The grinding assembly includes a rotary member 28 with an
outer surface 30 of grinding teeth 29 for engaging the ridge, the
rotary member being rotatable about an axis transverse to the
beam.
[0022] The grinding member has a width W transverse to the beam
which is approximately equal to the width of the ridge, typically
of the order of 12 to 18 inches and much less than the length of
the ridge or the width of the lane so as to grind only the ridge as
the grinding assembly moves across the beam.
