Ensuring the success of new Superflat Floor Installations

For new superflat floor installations we provide a full range of slab design, specification, and construction consultation services. Our on-site superflat quality control division tests each new future wheel track profile daily to ensure that all six of the Fmin tolerances are met.

Why Superflat?

For the lift trucks to operate at full speed with minimum risk of wire guidance problems, the wheel tracks in Defined Traffic VNA warehouses have to be extremely flat and level– in fact, “Superflat”.

Since weight and stability considerations require the lift trucks’ axles to be mounted with no springs or shocks, every deviation in the floor imposes some kind of lateral and/or longitudinal angular acceleration on the truck. These deviations are the features directly controlled by the Fmin system.

How To Make The Floor Superflat?

While under construction, Superflat floors must be tested every day to confirm their compliance with the specified Fmin tolerances. After each day’s pour, a technician goes out on the slab with his D-Meter, surveys the future wheel tracks, and then analyzes the collected data against the specified Fmin number. If the floor meets the specification, the contractor’s construction methodology is confirmed, and the installation may continue unchanged. If the analysis shows significant defects, then the need for improvement in the contractor’s procedures is definitely indicated. Drawing upon Allen Face’s 35 years in Superflat construction, a key part of AFE’s role is to provide the necessary procedural recommendations to ensure the floor installation’s ultimate success

Our services related to Superflat Technology:
  • Testing each aisle for Fmin immediately after installation
  • Analyzing the collected Fmin data and creating the Defect and Grinding Reports
  • Instructing the finishing crews in how to achieve better results
  • Overseeing any corrective grinding required (refer to ‘Corrective Grinding’)
  • Issuing a final certification report – recognized by all major lift truck suppliers – confirming the floor’s compliance with all the manufacturer’s floor profile requirements.
