​This KMS article provides information and examples on how to calculate floor loading (lb/in²) and potential pull up force (lb/in²) based on your Prodigy Balance base unit and guide wall system. 
Background Information
  • The Prodigy Balance base unit assembly weighs 1,400 lb. 
  • The weights (and pins) within the Prodigy Balance base unit assembly weigh 1,200 lb. 
  • The footprint of the Prodigy Balance base unit is 19.96” deep x 6.25” wide . 
  • The footprint of the guide wall is 5.25" deep x width of the wall section. 

 

Balance Floor Loading Calculator

The Balance Floor Loading Calculator is a resource to assist in determining the applicable loads the Prodigy Balance System will apply to the building. This information is intended to help a qualified individual make determinations related to the system’s interaction with the building.

The load values provided are pertinent to the Prodigy Balance Guide Wall and Balance Base Units, installed as the ETC drawings indicate.  Any changes in design or during installation will alter the values provided and they will then need to be recalculated.  In all cases, it is recommended that a licensed structural engineer verify that the provided loads are suitable for the designed building structure. ETC is strictly a provider of the load information and does not assume responsibility for building load verification.

Instructions
  1. Input Project Information.
  2. Input quantity of Balance Base Units.
  3. Input quantity & ETC part numbers of Guide Wall components found on drawings or Sales Acknowledgement.
  4. File, print – Landscape orientation, letter size.

Floor Loading - Calculations

Prodigy Balance Base Unit  - 
  • Floor Loading = (weight of Prodigy Balance base unit) / (footprint of Prodigy Balance base unit)
    • Example:  Floor Loading = (1,400 lb) / (19.96" deep x 6.25" wide) = 11.22 lb/in²
Guide Wall System - 
  • Floor Loading = (weight of guide wall) / (footprint of guide wall)
    • Example (1 line set wide guide wall 58'-0" high):  Floor Loading = (756 lb) / (5.25" deep x 16" wide) = 9 lb/in² 
      • Note: See example below for details about finding the weight and width of guide wall.

Potential Pull Up Force - Calculations

  • Pull Up Force = ((weight of weights and pins) - (weight of guide wall)) / (footprint of guide wall)
    • Example (1 line set wide guide wall 58'-0" high):  Pull Up Force = (1,200 lb - 756 lb) / (5.25" deep x 16" wide) = 5.29 lb/in²
      • Note: See example below for details about finding the weight and width of guide wall.

 

Calculating Weight (and finding width) of Guide Wall
  1. Calculating Weight of Guide Wall
    1. Determine the weight of your guide wall (base, mid section(s), and top cap components ) by using the Guide Wall Section Sizes and Weights table below. 
      1. Example:  Determine the weight of a guide wall system consisting of 1 line set that is 58'-0 tall. This guide wall system would consist of one (1) 20' base section with 1 line set, one (1) 20' mid section with 1 line set, one (1) 10' mid section with 1 lift line, one (1) 8' mid section with 1 lift line, and one (1) top cap with 1 lift line. 
        1. Base:
          1. Qty 1 of 8007A1108-20-1    (Description: BALANCE GUIDE WALL BASE 8" 20'H X 1LS W) 
            1. This is a 20' tall base section that has 1 line set. Using the table below, the weight for this part is  247 lb. 
        2. Mid Sections:
          1. Qty 1 of 8007A1008-20-1    (Description: BALANCE GUIDE WALL 8" CTR 20'H X 1LS W) 
            1. This is a 20' tall mid section that has 1 line set. Using the table below, the weight for this part is  250 lb. 
          2. Qty 1 of 8007A1008-10-1    (Description: BALANCE GUIDE WALL 8" CTR 10'H X 1LS W) 
            1. This is a 10' tall mid section that has 1 line set. Using the table below, the weight for this part is  134 lb. 
          3. Qty 1 of 8007A1008-8-1    (Description: BALANCE GUIDE WALL 8" CTR 8'H X 1LS W) 
            1. This is an 8' tall mid section that has 1 line set. Using the table below, the weight for this part is  113 lb.
        3. Top Cap:
          1. Qty 1 of 8007A1208-1    (Description: BALANCE GUIDE WALL CAP 8" CTR - 1LS W) 
            1. This is a top cap section that has 1 line set. Using the table below, the weight for this part is  12 lb.
    2. Add up the weight of all components in guide wall. 
      1. 247 lb + 250 lb + 134 lb + 113 lb + 12 lb = 756 lb
  1. Calculating Weight of Guide Wall
    1. Use the table below to determine the width of your Guide Wall section based on the number of Line Set(s). 
Guide Wall Section 1 Line Set 2 Line Sets 3 Line Sets 4 Line Sets 5 Line Sets 6 Line Sets 7 Line Sets 8 Line Sets 9 Line Sets 10 Line Sets
Width (inches) 16" 24" 32" 40" 48" 56" 64" 72" 80" 88"
