What does the code require with regard to equipment anchorage?
The California / International Building Codes require all stationary equipment to be anchored to its supporting structure (CBC 2007, Section 1613a & IBC 2006, Section 1613). In addition, much of this equipment must have calculations to validate its method of anchorage (ASCE 7-05, Section 13). For ceiling or wall supported equipment, a calculation must be provided for any piece of equipment that weighs 20 pounds or more. For floor mounted equipment the requirement is for equipment that weighs 400 pounds or more or is over 60 inches in height. An exception to this requirement is if the unit is “Mobile”. The state defines Mobile as the unit needs to move in order to fulfill its function … or “move it to use it”. Many units are on casters but are in a single location for long periods of time and are only moved during servicing. This is not considered mobile.
