How do you hook up to the trailer

when uncoupling a trailer remember to take off all ur lines...i had a very embarassing and expensive moment when i un coupled the trailer and forgot about the 2 hydraulic hoses that were still attached to the truck $400 later and 2 quick connect couplers later i learned a quick walk around before unhook a trailer is worth its weight in gold

and mud sucks when u got 56900lbs in the box couple of 4x4 pieces of wood fixed that though so no biggie

 

remember check the tandems!!!!! sometimes people like to play pranks and its not FUNNY! when its you explaining whthe trailer just wen thru the fence or as one I saw a fender on a new truck.

 

Its 21 for drivers to truck outside their home state. 18 to truck in home state.

so for canadians no trucking into USA until 21

and in canada drivers can truck anywhere in canada at age 18

 

I can only relate how I hook up trailers, not how its done in the books

 

The way you are describing this;
1. New plastic air lines (coil type) can get stretched out by hooking with a distance between tractor and trailer.
2. All the space between cat walk and trailer is potential for slip and fall.
3. Stretching the air lines will definitely get them greasy when you close the gap in hooking to the trailer.

Charging the air to the trailer before backing under means the trailer will roll...what would be holding the trailer in place to get a connection on the king pin?

I think you are confusing hooking to the trailer with doing the pre trip inspection. Doing the inspection without charging the brakes...how can you tell if there is an air leak anywhere between tractor and tandems?

NOPE

What difference would spring or drum brakes have on hooking to a trailer...schools are notorious for having instructors that really enjoy passing on the BS when "explaining" how something is done...along with the "horror stories" the instructor has somehow survived "back in the day" when he/she was driving! Just use some common sense about what you will accept as truth v BS!

 

Ontario is so out of date, its funny.

Old trailers did not have spring parking brakes, they had air holding the brakes on a dropped trailer, but once the air leaked down the parking brakes released, so to hook to them, you did have to hook up the air lines, press in the red button, to build air in the trailer tanks, then either pull the red button to apply parking trailer parking brakes or else pull the spike to apply the service brakes before backing under.

Ontario roadtest books still think we are in the 1960's LOL

 

I do not do it according to the book either.....

 

nt.........................................

 

ok, just for giggles here it is according to the book, and again, I do not know of anyone who does it like this, other than to get their licence.

Coupling:

Be sure fifth wheel jaws are fully opened and the fifth wheel is tilted back so that hook up can be made without damage. Make a visual inspection of the condition of the king pin and fith wheel. If the tractor is not equipped with a trailer hand valve or an emergency control valve, the trailer wheels must be blocked.

Back the tractor so the efifth wheel slot is in line with the trailer kingpin.

Stop the tractor just as the fifth wheel makes contact with the trailer.

Secure the tractor and check to see the trailer is secured against movement before coupling.

Connect the brake lines and light cord to the trailer before coupling.

Open ####s or actuate the control valve on the dash in the cab to charge the trailer air system.

Release the trailer hand control valve and listen for exausting air to determine whether the trailer brakes are operating.

Be sure the trailer brake lines are properly connected............................

Before backing gunder the trailer, check the height of the triler in relation to the fifth wheel. The trailer should be at a height where moderate resistance is met as the fifth wheel contacts the trailer plate.

Back slowly under the trailer. See that firm contact is made between the fifth wheel and the upper plate on the trailer. Continue backing until you hear the jaws lock.

...................................then it continues to tell you how to test the hook up.

So, Otherhalf, there you have it. Stright from the handbook . The Official Truck Handbook for Ontario truckers.

 

curious, did you ever hook up an old trailer that did not have spring brakes?

that would make a diference as to how you would hook up trailers, and Bikerboy explained it, as the reason why.
