Why would you move a fifth wheel when towing a semitrailer? Fifth Wheel

You’ve hooked up your trailer and you’ve headed to a weighbridge and the bad news is that your front (steering) axle is overloaded. An overloaded axle is both illegal and dangerous. It can overheat your tyres, make your braking performance much worse, affect your steering and even cause a jackknife if it’s bad enough.

Whoever loaded the trailer has put too much weight at the front, but you don’t have any ability to change that, so what can you do?

Why would you move a fifth wheel when towing a semitrailer? Fifth Wheel

 

Ако имате плъзгане пето колело, you can move the load backwards so that more weight is over the tractor unit’s drive axles.

Why would you move a fifth wheel when towing a semitrailer? Fifth Wheel

It’s common for drivers to move the fifth wheel, not only for weight distribution, but also to get the best aerodynamic performance from the vehicle. A smaller distance between the cab and the trailer makes for better fuel economy, but it’s not always possible to do this if the front of the trailer is heavy because too much weight will be over the steering axles.

Add to this the complication of full vs empty fuel tanks (diesel weighs around 8 pounds per gallon) and you’ll see it’s difficult to calculate an exact weight distribution.

Ако вашият влекач има подвижно пето колело, зад кабината ще има превключвател за отключването му.

When the fifth wheel is unlocked, it can slide on this notched rail. Each notch represents a certain percentage of weight distribution forwards and backwards – you’d need to check the manufacturer’s documentation to know just how much.

Как да преместите плъзгащото се пето колело

  1. Уверете се, че спирачките на ремаркето са задействани и че полуремаркето е здраво свързано
  2. The trailer must be in line with the tractor unit – you can cause damage if it isn’t
  3. Отключете петото колело с помощта на превключвателя
  4. Преместете главния двигател напред, за да промените баланса на теглото повече върху задвижващите колела и обратно
  5. Поставете ръчната спирачка на влекача
  6. Излезте и заключете петото колело
  7. Проверете го отново на кантара

След като оставите ремаркето, върнете петото си колело в нормалното му положение.

Какво да проверя

  • Before you try to move the trailer, check both slider plunger pins are out (there’s one either side)
  • Once you’ve moved the trailer, ensure that both slide plunger pins have moved back in. If they won’t go back in, move the tractor unit forwards or backwards slightly to take any pressure off the connection
  • Проверете дали уредът се обслужва редовно и има достатъчно грес
  • Do a tug test before you drive away – if the pins are unlocked, the first time you brake, the trailer will slide forward and break the coupling.

Можете ли да преместите петото си колело?

Не всички пети колела могат да се движат, докато са прикачени към ремарке. Това пето колело може да се движи, но само като развиете болтовете и го плъзнете напред или назад.
