Installing a cable drag chain is a process that requires precision and meticulousness to ensure the safety of cables in dynamic applications and the efficient operation of machines.
Here are the basic steps and precautions for installing a cable drag chain:
Planning the cable path: Before installation, the cable drag chain path should be planned to ensure that it can meet the needs of machine movement while avoiding unnecessary bending or twisting.
Choosing the right drag chain size: Choose the right drag chain according to the size of the cable and hose. There should be enough space inside the drag chain, and the minimum clearance recommended is usually 10% of the outer diameter of the cable.
Installing the drag chain: Fix the drag chain to the machine or structure using appropriate mounting brackets. Make sure that one end of the drag chain is fixed to the static part and the other end is connected to the moving part.
Placing the cables: Place the cables in the drag chain, making sure they are not twisted or overlapped. The cables should be placed in the drag chain in a non-twisted flat form and should have at least 10% extra length to allow them to lie freely in the drag chain without twisting.
Using dividers: If cables of different sizes are mixed in the drag chain, dividers or separators should be used to keep the proper distance between them and avoid rubbing against each other.
Ensure free movement of cables: Cables should be able to move freely within the drag chain and should not appear forced or restricted.
Secure cables: Secure cables at one end of the drag chain, ensuring they have enough slack to accommodate the movement of the drag chain as it moves.
Balance weight distribution: Ensure that the weight of the cables within the drag chain is evenly distributed, with heavier cables installed at the edges and lighter ones in the middle.
Check minimum bend radius: Ensure that the design of the drag chain allows for a minimum bend radius for the cables to avoid cable fatigue and damage.
Regular inspection and maintenance: Even after proper installation, the drag chain needs to be inspected and maintained regularly, checking for signs of wear, abrasion or damage, and performing maintenance promptly.
