Abstract
An example includes a concrete grinding apparatus with a jackshaft configuration to efficiently transmit torque from an engine to a grinding arbor. An example includes a method of grinding a road lane in two passes. An example includes a vacuum system to generate vacuum with a centrifugal pump to collect debris and cool a grinding arbor.
Claims20
A method of grinding a road lane in two passes, comprising:
- aligning a concrete grinder having a grinding arbor such that the grinding arbor extends normal to a lane direction, extending from a first edge of the lane to a center of the lane to cover a first half-lane;
- grinding the first half-lane to a first substantially flat surface;
- aligning a concrete grinder having a grinding arbor such that the grinding arbor extends normal to a lane direction, extending from a second edge, of the lane, opposite the first edge, to the center of the lane to cover a second half-lane adjacent the first half-lane;
- and
- grinding the second half-lane to a second substantially flat surface that intersects with the first substantially flat surface.

A method of grinding a road lane in two passes, comprising:
- generating a moment with an engine, the moment extending around a lane direction of travel;
- translating the moment to normal with the lane direction of travel with a central gearbox and applying the moment to a first axle and a second axle;
- driving a first half of a half-lane grinding arbor with a first portion of the moment;
- driving a second half of a half-lane grinding arbor with a second portion of the moment;
- aligning a concrete grinder having a grinding arbor such that the grinding arbor extends normal to a lane direction, extending from a first edge of the lane to a center of the lane to cover a first half-lane;
- grinding the first half-lane to a first substantially flat surface;
- aligning a concrete grinder having a grinding arbor such that the grinding arbor extends normal to a lane direction, extending from a second edge, of the lane, opposite the first edge, to the center of the lane to cover a second half-lane adjacent the first half-lane;
- and
- grinding the second half-lane to a second substantially flat surface that intersects with the first substantially flat surface.

A method of grinding a road lane in two passes, comprising:
- generating a moment with an engine, the moment aligned transverse to a lane direction of travel;
- driving a jackshaft with the moment;
- driving a first half of a half-lane grinding arbor with a first portion of the moment;
- driving a second half of a half-lane grinding arbor with a second portion of the moment;
- aligning a concrete grinder having a grinding arbor such that the grinding arbor extends normal to a lane direction, extending from a first edge of the lane to a center of the lane to cover a first half-lane;
- grinding the first half-lane to a first substantially flat surface;
- aligning a concrete grinder having a grinding arbor such that the grinding arbor extends normal to a lane direction, extending from a second edge, of the lane, opposite the first edge, to the center of the lane to cover a second half-lane adjacent the first half-lane;
- and
- grinding the second half-lane to a second substantially flat surface that intersects with the first substantially flat surface.
