Floor loading and wheel loads: assessing forklift use inside buildings
Before a forklift is used inside a building, it must be established whether every surface on its route can withstand the loads imposed. The truck’s rated capacity is not sufficient for this decision: the specific forklift configuration, actual load and confirmed load-bearing capacity of the relevant structural areas are decisive.
Key points at a glance
- Establish the service weight of the specific forklift configuration and the actual weight of the goods from reliable documentation.
- Account for wheel and axle loads, tyres, contact area and dynamic effects during travel, turning and braking.
- Assess the entire route separately, including ramps, dock levellers, lifts, mezzanines, suspended floors and transitions.
Combine truck data with the building’s load-bearing capacity
Weight is not distributed evenly across the floor under all operating conditions. The load, its position, the tyres and their contact area affect wheel and axle loads. Starting, braking and turning also produce additional dynamic effects. Floor approval must therefore not be based solely on the forklift’s rated capacity or a general total load.
The assessment requires the binding data for the selected forklift configuration and the confirmed load-bearing capacity of every affected part of the structure. Travel routes, ramps, dock levellers, lifts, mezzanines, suspended floors and transitions may have different limits. Suitability must be confirmed by the building owner or operator and, where necessary, by a structural engineering specialist.
Plan forklift use with verified data
Compile the data for the intended forklift configuration, actual loads and complete travel route. Any open questions about truck selection and the building’s load-bearing capacity should be clarified with the responsible specialists before operation begins.
Frequently asked questions about floor and wheel loads
Is the general floor load capacity sufficient?
No. It must be assessed for the actual areas travelled and for the wheel, axle and dynamic loads imposed by the specific forklift configuration.
What data is needed for the assessment?
The required data includes the service weight of the specific configuration, the actual weight and position of the load, wheel and axle loads, tyres, contact area, operating movements and details of every part of the structure used by the truck.
Who confirms suitability for forklift use?
The truck values come from the binding documentation for the selected forklift. The building’s load-bearing capacity must be confirmed by the owner or operator and, where necessary, by a structural engineering specialist.
