Kenworth 客戶服務中心提供關於 第五輪 小心謹慎。檢查拖車架時,首先要考慮安全問題。駕駛員可以採取以下措施:
•Keep the fifth wheel lubricated.
•Make sure that it is still connecting properly to the trailer.
•Verify that a sliding fifth wheel is locking properly.
•All this can and should be done without touching the fifth wheel yourself.
在開始檢查之前,請徹底對整個第五輪系統進行蒸氣清潔。清潔頂板、支架、滑板、安裝角落和緊固件。接下來,為了更好地觀察第五輪,可以使用故障燈或手電筒進行目視檢查。預計此步驟需要10到15分鐘。
Test those jaws. This is the safest way to examine your fifth wheel’s jaws and make sure they aren’t worn out…it’s a two-person test, so ask someone to help you out for a moment.
•Latch the fifth wheel onto the trailer as usual.
•Set the trailer brakes.
•Have your assistant stand where he or she can see the fifth wheel.
•Move the chassis back and forth slightly.
•Have your assistant watch to see if the plate moves relative to the trailer.
如果板確實移動,則卡爪可能已磨損。如果卡爪已磨損,則第五輪可能需要重建而不是更換,因此請諮詢您的供應商或經銷商。
It is possible to have fifth wheels adjusted, but it’s not typically necessary. Talking with Jost, Kenworth learned that this is not something that usually needs to be done with their products, and in fact, frequent adjustments can cause premature wearing of the locking mechanism. Jost states it has many fifth wheels in service with over 400,000 miles on them that have not needed adjustment.
Fontaine said that if it’s needed, its fifth wheels are easy to adjust—they can even be adjusted while the trailer is coupled to the fifth wheel if the situation calls for it.
