Grinding attachment

摘要

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.

主权项

1. A grinding attachment mountable on an existing main shaft of a highway grinding vehicle, the 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 at one end for direct mounting on the existing main shaft of the highway grinding vehicle, thereby supplying a source of torque to the grinding attachment; a floating stub axle having a bearing internal to, and located within, the arbor extension which operatively engages the arbor extension at an opposite end of the arbor extension; and a mounting assembly to support the floating stub axle and mount the grinding attachment to the highway grinding vehicle; wherein the grinding drum can thereby operate proximal to obstacles adjacent a grinding surface, and wherein the grinding attachment is mountable to the existing main shaft of the highway grinding vehicle.
