Calculate The Required Cable And Hose Clearance Requirements For The Carrier System Cavity
Step 1
1.) To determine the required carrier system inner cavity height h i , you must:
“X”
b i
cavity area
h i
carrier link cross sectional view
a.) Add the following required clearance Safety Factor ( SF ) around all your cables, pneumatic lines, and/or hydraulic hoses:
Cables → Add 10% to the outside diameter
minimum clearance around the O.D. = "X" must be > 1.0 mm
Pneumatic Lines → Add 15% to the outside diameter minimum clearance around the O.D. = "X" must be > 2.0 mm Hydraulic Hoses → Add 20% to the outside diameter minimum clearance around the O.D. = "X" must be > 3.0 mm
b.) The largest of these cable, air line or fluid hose outer diameter values, with the safety factor added (Ø +SF ), determines the minimum inner cavity height required ( h i ). ■ Make note of the largest c Ø + SF , pn Ø + SF and hyd Ø + SF values in your application and use the largest of these as the minimum required h i value. 2.) To determine the required carrier system inner cavity width ( B i )
cavity area
B i
h i
carrier link cross sectional view
a.) Add up all the aforementioned cables, air lines and fluid hoses plus safety factor values.
∑ c Ø + SF + ∑ pn Ø + SF + ∑ hyd Ø + SF = ∑ ALL Ø

good
not recommended
Cable/hose weight is unevenly distributed inside the carrier cavity causing unbalanced carrier system operation which could result in system failure
Cable/hose weight is evenly/symmetrically
Cable’s/hose’s outer diameter takes up the entire cavity causing premature wear on the cables/hoses and carrier system
Space in each cavity partition allows for the cable/hose outer diameter plus the recommended safety factor
distributed inside the carrier cavity allowing for balanced carrier system operation
