Abstract
A grinding attachment for highways and similar surfaces is disclosed for grinding operations closer to adjacent obstacles than is possible with existing equipment using a straddle-type centrally mounted grinding drum. The grinding attachment assembly comprises at one end a stub axle, which engages the grinding drum via a head extension. The stub axle is attached to a shroud which is in turn supported by a mounting assembly, which in operation attaches to a vehicle or machine able to drive the grinding attachment. The grinding drum can thereby operate proximal obstacles adjacent a grinding surface by virtue of arrangement of the stub axle, shroud and mounting assembly.
Claims6
A grinding attachment comprising:
- a longitudinally oriented arbor extension for mounting grinding blades and spacers thereon to form a grinding drum, the arbor extension being adapted for engagement and support at one end to a head shaft supplying a source of torque to the arbor extension;
- a stub axle to engage and support the arbor extension at an opposite end of the arbor extension;
- and
- a mounting assembly to support the stub axle and mount the grinding attachment to a highway grinding vehicle or machine able to drive the head shaft;
- wherein the grinding drum can thereby operate proximal to obstacles adjacent a grinding surface.
