Ngano nga ibalhin nimo ang ikalimang ligid kung magguyod sa usa ka semitrailer? Ikalima nga Ligid

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

 

Kung naa kay sliding ikalima nga ligid, 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.

Kung ang imong tractor unit adunay usa ka mapalihok nga ikalima nga ligid, adunay usa ka switch sa luyo sa taksi aron maablihan kini.

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.

Unsaon paglihok sa sliding fifth wheel

  1. Siguruha nga ang mga preno sa trailer gipadapat ug nga ang semitrailer lig-on nga konektado
  2. The trailer must be in line with the tractor unit – you can cause damage if it isn’t
  3. Ablihi ang ikalimang ligid gamit ang switch
  4. Ibalhin ang prime mover sa unahan aron mabag-o ang balanse sa gibug-aton sa mga ligid sa pagmaneho, ug vice versa
  5. Ibutang ang parking brake sa tractor unit
  6. Paggawas ug kandado ang ikalimang ligid
  7. Susiha kini pag-usab sa weighbridge

Kung nahulog na nimo ang trailer, ibalik ang imong ikalima nga ligid sa naandan nga posisyon niini.

Unsa ang susihon

  • 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
  • Susiha nga ang yunit kanunay nga giserbisyuhan ug adunay igo nga grasa
  • 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.

Mahimo ba nimo ibalhin ang imong fifth wheel?

Dili tanan nga ikalima nga ligid mahimong ibalhin samtang gidugtong sa usa ka trailer. Kining ikalima nga ligid mahimong mapalihok, apan pinaagi lamang sa pagtangtang sa mga bolt ug pag-slide niini sa unahan o paatras.
