Load capacity calculation
The difference between the tested conditions and the real conditions is taken into account by the safety factor. The value of the safety factor can only be determined by a person (designer) who knows the working conditions of the wheels as well as the relevant STN. RENOST consulting can only recommend the value of the factor based on the available information, without guarantee.

It determines the deviations of standardized conditions (STN EN 12 527, 12 532) from real ones, which ensure the surface, speed of the device, height of thresholds, slope of slopes, uniformity of load distribution, direction of movement of the roller and wheel, temperature (+15 °C to +28 °C).
β = 1,3 - 1,5
manual handling in standard conditions, flat cast floor, occasional handling
β = 1,6 - 3,9
manual handling in adverse conditions - sloping exits, uneven elevator entrances, uneven floors, car exit ramps, frequent handling
β = 4,0 a viac
for machine-towed equipment in continuous operation, generally demanding conditions, not for powered applications
