Tensioning
First Tensioning : The most important factor which affects the operation life is the tension of the TPC and achieving the correct tension is crucial. Tensioners or other devices are used to maintain the proper tightness, preventing excessive slack and ensuring optimal engagement with the tire. The tension should be checked and the tension should be adjusted first at 100 hours.
Proper Tension : The chain which can not be handled at all is over-tensioned or the chain which can be handled more than 5 cm is too much loosen. Over-tensioned chain or too much loosen chain will be broken or wear off easily or even may damage the tire.
For new tires; A chain bag equal to 10% of the tire “face” width is advised to allow for tire expansion
during new tire break in.
On used and broken in tires; this can be reduced to 5% of the tire face width.
Example: 45/65-45 tire size 45” face width times 10% equals 4.5”. So a bag of 5” is ok. On a used tire
(30% or more wear) a 3” bag should work.
Regular Tensioning : If tension is checked frequently, the risk of damage is minimized. To ensure that tire protection chains securely wrap around the tires, tension should be checked at 250 hours, 500 hours, and then regularly thereafter to achieve the expected optimum lifespan and performance. In any case, checks and tension adjustments should be performed every 1,000 hours. Adjustments may vary depending on usage, tire conditions, and field conditions. During checks and adjustments, regular tensioning by the user or field team with online technical support, if needed, is expected.
