Calculating the length of a cable energy chain
The length of a cable energy chain required for a given application is dependent on three main factors.
1. The length of travel of the application.
2. The radius of the cable energy chain.
3. The location of the fixed point of the energy chain.
First confirm the length of travel, then determine the bend radius of the energy chain. (what's this?)
It is then necessary to establish the fixed point of the chain. In most cases, this will either be in the centre of the travel, or at the end of the travel.
For an energy chain fixed in the centre of the travel.
The most efficient place to fix a cable energy chain is at the centre of the travel.
By fixing it in the centre you will need the shortest length of chain to achieve it.
Length of chain required = (Length of Travel / 2) + (Radius x 4)
For an energy chain fixed at the end of the travel.
For ease of installation or with some long travel systems it may be best to fix the chain at the end of the travel.
Length of chain required = Length of travel + (Radius x 4)
Above is a sketch showing the difference between an energy chain fixed at the centre of the travel and one fixed at the end. Even though one chain is longer than the other, each acheives the same length of travel.
The above formula is only a rough guide for making a quick assessment. Some energy chain and long travel applications other factors will need to be considered.
