Floor Flatness (SUPERFLAT)


Floor Flatness Comes First

Floor Flatness is critical in the majority of warehouse floors, where the need to increase efficient use of space often means reducing aisle widths and selecting Very Narrow Aisle (VNA) racking systems. This in turn requires specialised VNA Lift Trucks or Materials Handling Equipment (MHE). These Lift Trucks known as Man-up Lift Trucks allow the operator to travel up and down in a cab with the load. The clearance between the sides of the Lift Truck with the pallet it carries, and the Racking may only be 100 - 150 mm on each side. Latest generation MHE and Racking systems can reach hts of 18m or more.

Why Floor Flatness is important

In summary, exact floor flatness is crucial for the following reasons:
• Operations are more effective if lift trucks can operate at Maximum speed.
• Surface unevenness will lead to excessive vibration on a lift truck and increase down time and repairs.
• Health & Safety is increased while operator tiredness is decreased.
• Decreasing the liability of damage to stock.
• Provides control on the general quality of a floor once constructed.

More About the Importance of Floor Flatness

If the floor is not flat this causes a number of issues, as the MHE starts to shake about.

Decreased Operational Efficiency
One issue is that the operator feels uncomfortable or even unsafe and will drive much more slowly, he will also travel with the cab in the down position to the pallet location, then stop moving before elevating the cab/load to the required height. This significantly reduces operational efficiency and will reduce the numbers of pallets that can be handled in any given time.

Increased Operational Costs
Where throughput is important this can actually mean that a second MHE has to be purchased to increase the number of pallets being handled. Another issue is reliability of the MHE - such equipment does not like continual vibration, and this results in electronic component issues as well as accelerated tyre wear and wheel bearing damage, which all leads to significantly increased Maintenance costs.

Unevenness in the floor can also affect stress to the chassis which has no springing, particularly in the case of rail guided trucks, and even worse in the case of wire guided trucks the unevenness might even cause the truck to come off the wire.
