Here are the steps of corrective Spot-grinding:
We are surveying the narrow aisle in the truck wheel tracks with a D-meter using a fixed pattern to create a complete set of vertically correlated wheel track profiles, collecting data in 30 cm increments in each track.
The recorded data evaluate using the Grinding Optimization software.
The obtained “map” will indicate in the wheel tracks along the aisles’ entire length and the depth of grinding required at each spot to bring the wheel tracks into full compliance with the specified Fmin. It guarantees the optimum speed of the lift truck in the given aisle, according to the type of truck used -via the control of the six variables on the Fmin measurements tab.
We grind to the appropriate level in the spots indicated by the “map,” where necessary (and only there).
We grind the individual spots together to achieve the desired surface evenness in the wheel tracks.
We re-evaluate the flatness in the wheel tracks and make any necessary corrections. Determine the aisle’s Fmin values by repeated measurements and prepare the corridor classification according to the Fmin system.
