An alternative for traditional FIFTH WHEELs - with a couple of dismountable UHMWPE (ultrahigh molecular weight polyethylene) plates on the surface of a FIFTH WHEEL.
The concrete advantages of the newly-designed construction for FIFTH WHEELS are as following:
1. Super wear resistance - 6 times more than the plain carbon steel.
2. Quite low coefficient of friction / capacity of self-lubricant - no extra lubricant needed (to save your money)
3. Alternative by newly-processed plates when the old ones are to be updated.
4. Impact resistance.
5. Corrosion resistance.
6. Insulation.
7. Low temperature resistance - the same properities even when it is minus 200 degrees centigrade.
8. Water repellant.
9. Long life-span for all the integration of the characteristics above.
