Why Proper Fifth Wheel Maintenance is Important Fifth Wheel

Runaway trailer hits minivan.” That’s what the headline screamed. While the details of why the trailer separated from the tractor in upstate New York have yet to be sorted out, the events underscore the important role the 다섯 번째 바퀴 트럭 안전에 영향을 미칩니다.

Like any safety-related component, the fifth wheel needs to be in good operating condition to do its job properly. “It’s important to maintain the fifth wheel because it is the sole component that connects the tractor to the trailer,” says Rob Nissen, director of field sales for SAF-Holland.

5륜 자동차 제조업체에서는 3개월 또는 30,000마일마다 5륜 유지관리를 수행할 것을 권장합니다.

 
 

“You need to lubricate it through all four seasons,” says Charles Rosato, field service manager for Fontaine Fifth Wheel. “That also gives you four chances to inspect it each year.” If you choose not to do that, you should at least clean the locking mechanism every six months or 60,000 miles.

However, lubrication is not the only maintenance needed on a fifth wheel. According to Mike Jones, senior account manager at Jost, it’s important to inspect the fifth wheel for damage.

“Before you can do that, you need to degrease it with a degreasing compound or steam cleaning device,” he says.

기름은 5륜차에 쌓이고 먼지와 이물질을 끌어들일 수 있으므로 검사하기 전에 기름을 제거하면 잠재적인 손상을 더 쉽게 확인할 수 있습니다.

“Get the old grease off and look for any cracks, broken welds, and damaged or missing components,” Rosato says. “You really won’t be able to see those things unless you get the grease off.”

잠금 장치, 스로트, 피벗 지점 안팎에 쌓인 기름때를 모두 제거하는 것도 매우 중요합니다. 특히 겨울이 오기 전에 이 작업이 매우 중요하다고 로사토는 말합니다.

“People keep adding grease [throughout the year] and you might be able to get away with that in the summertime,” he says. “But in the winter the old grease, which has picked up a lot of road grime and contaminants, can freeze. You could end up with a grapefruit-size piece of frozen grease inside your fifth wheel, and that will keep the lock from operating properly.”

His recommendation is to thoroughly degrease the fifth wheel and then regrease the mechanism with a thin coat of 90-weight gear oil. Jones says it’s important to use a lithium EP (extreme pressure) grease on the plate if you want to ensure the fifth wheel operates smoothly.

Just as important as winter fifth wheel service is servicing it in the spring. “The lube get washed off or worn away because of winter conditions,” Nissen says. “In addition, the sodium chloride and magnesium chloride that states are putting on the roads are brutal not just on fifth wheels but on other components as well.” According to Nissen, those deicing chemicals can dry out the fifth wheel and cause rust to form. “When things get rusty and corroded, everything starts moving slower and that is a problem because the coupling and uncoupling of the fifth wheel depends on timing. Things need to be free and loose so the [tractor and trailer] can snap into place.”

A maintenance manual from SAF-Holland sums up the importance of fifth wheel maintenance. “Failure to properly maintain your fifth wheel could result in tractor-trailer separation which, if not avoided, could result in death or serious injury.”

Nissen says, “To me it is worth an hour of your time to clean the fifth wheel, look at it, check the adjustment, and relubricate it before putting it back on the street, because one failure can be catastrophic.”
