Dynamic Loads

Rolling loads are typically imposed by equipment on wheels moving across the access floor. They are defined by the number of passes, size and hardness of the wheel and the combined weight of the cart and its contents, on each wheel. Rolling loads are the most important performance criteria because they have a more damaging effect on the panel than a static load.

Here are some common rolling load conditions:

• Move-in-Equipment
  Caused by furniture dollies or computer equipment with small, hard wheels traveling a random path during move-in and furniture/equipment rearrangements.
• Manual Carts
  Caused by supply carts and paper dollies used daily to deliver supplies and materials rolled across floor surface.
• Electric Carts Caused by electric carts or mailmobiles and their contents traveling over the same path for a substantial period of time.

Impact loads are imposed by objects accidentally dropped onto an access floor. These loads are defined by the weight of the load and the height or distance dropped. Impact loads generate severe shocks which can cause structural and panel damage. Impact loads most often occur during construction, move in and equipment/furniture rearrangements.
