What Sizes Are Big Foot Systems?

Big Foot Systems standard frames are constructed from 40×40 box section, available in lengths ranging from 1m to 4m, and offered in widths of either 1.2m or 1.5m. These modular frameworks come equipped with feet measuring 305mm or 450mm, suitable for a variety of installation requirements where non-penetrative support is necessary. The size and design of Big Foot Systems can vary significantly depending on several factors:

  1. Type of Air Conditioning Unit: The size of the system is largely determined by the type and size of the air conditioning unit it supports, which can range from small residential units to large commercial rooftop units.
  2. Weight of the Unit: The primary function of the system is to provide stable support for the air conditioning unit. Consequently, the structure’s size is designed to bear the weight of the unit, with heavier units necessitating larger and more robust supports.
  3. Structural Requirements: The system’s size may also depend on the building’s structural requirements where the air conditioning unit is installed. For instance, a rooftop installation might require a different size and design than a ground-level installation.
  4. Environmental Factors: Wind load, seismic activity, and weather conditions are environmental factors that can influence the support system’s size and design. Areas prone to high winds or earthquakes might require a sturdier system.
  5. Installation Space: The available space for installation can dictate the system’s size. Limited or irregular spaces might necessitate a specifically sized and shaped support structure for a proper fit.

In summary, the dimensions of a Big Foot System for air conditioning units are adaptable to meet the unique needs of the unit, the structural and environmental demands of the installation site, and any customization or special requests. Professional consultation and guidance from the air conditioning unit’s manufacturer are crucial to determine the appropriate size and design for a support system.
