Floor loading examples

The following table provides estimated floor loading values for the 3932.

Floor loading is a function of system weight, system area, clearance area around the system, and system installation environment (raised or non-raised floor).

Attention: Due to system weight variability, the following table does not cover every system configurations. The following table provides the maximum limits of floor loading for a system that meets the requirements for operation and serviceability.

The provided floor loading values are for installed systems. Systems that are surrounded by other equipment, such as in storage, can exceed a floor loading of 976 kg/M2 (200 lbs/ft2).

  • The minimum floor loading values are for a stand-alone installation with 5 ft of clearance space all the way around the system.
  • The maximum floor loading values are for a system that is being installed in the middle of an existing row. This scenario assumes that there is no side clearance area, a 3 ft hot aisle (rear), and a 4 ft cold aisle (front).
The system weight that is used to calculate the following floor loading values (minimum and maximum) assumes that all of the drawers are maximum plugged. The weight in each instance is the maximum.
Note: The Earthquake Kit hardware weighs approximately 43 kg (95 lbs). If this feature is ordered, you must add the following:
  • 2.3 kg/M2 (5 lbs/ft2) to the maximum floor loading values
  • 1.5 kg/M2 (3 lbs/ft2) to the minimum floor loading values
The following formula is used to calculate the floor loading values and is provided for your reference. You can use this formula to obtain the floor loading (FL) values for your specific system configuration.
FL (lbs/ft2) = k + (w + 120) / ((2 + a + d)*(4 + b + c)
  • k = 10 (raised floor environment) or 0 (non-raised floor environment)
  • w = System weight (lbs)
  • a and d = side clearance dimensions (ft)
  • b and c = front and rear clearance dimensions (ft)

See Weight distribution and floor loading for sample floor loading figures of the 3932.
