This one is with the trailer brakes set
This one is the trailer brakes released, notice the extra piece of metal grabbing onto the dolly eyelet.
Cool. Thank you Bobcat!

Doubles , Triples, and Pintlehook Dollies 101 ... I love this thread, so much. I never interacted when my ole' guy did this. Babies took precedence. Not that I'd ever go for this, but ... it's SOOOOOO educational, and I'm grateful. TYSM!
Can you guys, please (once again, clearer for the lack of my comprehension) explain what exactly that extra metal protrusion is for? Is it spring (or pneumatically) loaded, for safety of the rear trailer/dolly? Oh... wait, no air, so... duh.
Sorry if asked & answered; I really try to glean all I can from this thread, and I'm totally grateful, G'Town, and all !

OTR:
Over The Road
OTR driving normally means you'll be hauling freight to various customers throughout your company's hauling region. It often entails being gone from home for two to three weeks at a time.
Doubles:
Refers to pulling two trailers at the same time, otherwise known as "pups" or "pup trailers" because they're only about 28 feet long. However there are some states that allow doubles that are each 48 feet in length.
It’s air loaded lol when u supply air to your trailers it pushes against the dolly pintle to hold it in place.
Cool. Thank you Bobcat!

They really don't give the proper classroom training for doubles when you get the endorsement. Companies know this and provide extra training. Just like just about everything in life a little hands on experience is what matters most.

Thanks, G-Town for starting this thread, and Anne for being the catalyst. I am trying to get on with XPO in a local LTL gig, and likely will need to able to run doubles as part of it out of the 'zone' here. Have the endorsement, just never needed it at any of my prior outfits. The converters look an awful lot like a short bed inter-modal dolly, sans spring brakes. Is there any suspension on the dolly, or is it just an A-frame with wheels and a 5th wheel? Pre-trip on the dolly - tires, lines, missing bolts, etc - any other guidance on that? Also - thanks for list of tools and schtuff to have - always carry a tool kit that will allow me to keep rolling through minor stuff and that was good advice.
Thanks!!!
LTL:
Less Than Truckload
Refers to carriers that make a lot of smaller pickups and deliveries for multiple customers as opposed to hauling one big load of freight for one customer. This type of hauling is normally done by companies with terminals scattered throughout the country where freight is sorted before being moved on to its destination.
LTL carriers include:
- FedEx Freight
- Con-way
- YRC Freight
- UPS
- Old Dominion
- Estes
- Yellow-Roadway
- ABF Freight
- R+L Carrier

Our dollies have brakes and a spring suspension. They are pretty easy to pretrip since they are so short and everything is right there.
I check the lines to both lead and rear trailer, tires, brakes and suspension before taking off with it. Some people pretrip once everything is hooked up which is good for air leaks and light problems but sometimes you can catch something early and save some work.

Thanks, Bobcat. If you charge the air line to the dolly, even without the tail connected, you will detect air leaks in the lead and dolly connections, right? doing the pretrip on teh dolly wihtout anything on top is so much faster and more effective than when it's got a load, I found that with i/m chassis inspections. Thanks for the information.
