what is the procedure for hookin up doubles?

I have an ideal on this but need to know exactly how to do this ,especially the dolly hook up , breaking the set is the easy part i know but still would be good info ....yes I've been a driver for awhile but not much experience with this ,also any info on hooking buckets ( gravel trains)
and maybe talk about the dangers of tipping over a gravel trains while dumping a load .....you can never know too much.....shoot straight , drive safe " thanks guys "

 

Gotcha sir , so the trick is to line it up by hand , dolly &rear twin first but not connected , then with the first twin already connected back up close as possible to lining up with the pintle ( that's the tricky part i would guess ) & then crunching it together , that's makes sense now ....i imagine those dolleys would be fustrating sometimes
....thank you : ALLOW ME ...think im making a career change ,getting into LTL frght , i know it's a faster pace work for these old bones but i need a more solid company to get old at , im tired of building trucking companies that seem to go south on me & fall apart

 

I never pulled doubles, although I was required to get the classification on my CDL (1 trailer was enough) but I think you make sure the heavier wagon is hooked to the tractor.

....i agree for sure , you don't want to get ,what those guys call the " whip effect" , makes good sense especially on adverse road road conditions .....Thank you semi retired ,good info !!!

 

I've seen those gravel trains ,running empty and sometimes that back bucket , starts to whip at 60mph , i asked a driver once how he feels about that & how he calms it down .....he said : he gives it more throddle to straighten it out ,not sure i would like that on snowy roads ,but i don't really those guys much in the winter , those guys make a decent wage from what they say ....never met one yet that wasn't excited about their job , not that it's a great joy but there's room to take pride in what they do for a living ......workin hard & playin hard

 

You should still know how to hook them up but the guys that do the hard work in LTL generally only pull one trailer at a time. The linehaul guys are the ones that pull doubles or trips

 

When you have the dolly sitting in front of the rear trailer, throw a marker on the ground (glove) where the eye of the dolly sits, in line with the dolly wheel.
Then you have a 'target' to aim for when backing up your lead trailer, without bumping into the dolly and risking damage.

I connect the air and pigtail from the dolly to the lead trailer, put on safety chain, close air tank drain valve - and then back lead and dolly under rear trailer, but that's just me.

Important thing is to establish a safe routine, and stick to it. I make it a point to empty my tiny brain of all thoughts before hooking and dropping, so I concentrate on the task and don't forget anything - like lowering trailer legs, or removing air lines.

They're really not that difficult to drive - I've made the odd evasive maneouver and never gotten in trouble. Be careful if pulling empty - they can get squirrely on wet/slick roads if you brake aggressively.

Good luck - I think you'll enjoy the LTL.

 

....i agree ,
Im shooting for LTL p&d ...but they may ask me to run line haul until i have earned my way into the day shift , i hate the 3rd shift but hey for 60cpm ill hang for awhile ....im good at peddling frght & don't mind the hussle of the metro
