At this step, you should now have selected and noted the: 1. Carrier product group (system type, style and link size) 2. Carrier cavity size (cavity inner height h i and width B i ) 3. Carrier bend radius option (the best KR option of those offered for your application) Once you have double checked your selections, you can then move on to calculate the correct carrier system length L k that your application or machine requires.

Step 5 Determine The Carrier System Loop Length (LB)
To determine the total chain length needed for your cable carrier system in Step 6, you will first need to calculate the carrier's Loop Length ( LB ). The Loop Length ( LB ) dimensions can typically be found listed in the Technical Data section of each product section in the KabelSchlepp Catalog. To calculate the recommended Loop Length ( LB ) yourself, use the formulas listed in the table to the right.
Calculating Carrier System Loop Length (LB)
Plastic cable carriers: L b = (3.14 x KR) + (2 x t ) Steel cable carriers: L b = (3.14 x KR) + (4 x t ) QUANTUM cable carriers: L b = (3.14 x KR) + (12 x t ) PROFILE, CONDUFLEX cable carriers: L b = (3.14 x KR) + (9 x t )
Step 6
CL Calculate The Total Carrier System Length (Lk) Moving End ( ME )
Fixed Point ( FP ) To determine the most economical length of a KabelSchlepp carrier system, in all horizontal or vertical carrier system operating modes, use one of the first 3 formulas listed below to solve for the required carrier length ( L k ) and number 4 to solve for the number of links ( t ) needed.
Fixed End ( FE ) ME = Moving End of carrier system
FE = Fixed End of carrier system
FP = Fixed Point of carrier system
(Ls / 2) + LB = Lk
1.) FIXED POINT AT CENTER OF TRAVEL For a carrier system that has its fixed point located centrally relative to the total machine travel use:
