CAUTION: To reduce the risk of damage to the casters, make sure that the full weight of the rack rests on the leveling feet and feet pads, and not on the casters. The casters are designed only as an aid in moving the rack into position. They are not designed to support the weight of the rack, and the casters may become damaged if relied on to support the rack.
Common floor-loading terms
Term | Description |
|
|
Dead load | The weight rating for the load the floor can support expressed in kg/m² (lb/ft²) |
|
|
Uniform load | The load that the floor system can safely support; expressed in kg/m² (lb/ft² or kN/m²) |
Concentrated load* | The load that a floor panel can support on a 25 x 25 mm² (1 x 1 inches²) at the panels |
| weakest point (typically the center of the panel), without the surface of the panel |
| deflecting more than a predetermined amount |
|
|
Rolling load | The load a floor panel can support (without failure) when a wheel of specified diameter |
| and width is rolled across the panel |
