Quote From Page 0 Of The CDL Manual:
Many motor carriers have installed electronic devices in their trucks to help accurately record hours of service information. If such a device meets the requirements of the safety regulations, it is called an Electronic On-Board Recorder (EOBR), and may be used in place of a paper logbook.
EOBRs are slowly becoming the industry standard. If you are hired on with any large carrier, chances are very high that you will be using an EOBR. Many small companies still use paper logbooks, but EOBRs will soon take over.
- While idling in the lowest gear possible, pull out the trailer air supply control to see if you come to a safe stop
- While idling in the lowest gear possible, pull out the yellow parking brake control to see if you come to a safe stop
- While stopped, pull out the trailer air supply control and pull gently on the trailer with the tractor
- While stopped, pull out the yellow parking brake control and pull gently on the trailer with the tractor
Quote From Page 79 Of The CDL Manual:
Test trailer emergency brakes: Charge the trailer air brake system and check that the trailer rolls freely. Then stop and pull out the trailer air supply control (also called "tractor protection valve control" or "trailer emergency valve") or place it in the "emergency" position. Pull gently on the trailer with the tractor to check that the trailer emergency brakes are on.
- The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
- A combination of securing devices which form an assembly that attaches cargo to, or restrains cargo on, a vehicle or trailer, and is attached to anchor point(s).
- The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
- The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
Quote From Page 1 Of The CDL Manual:
Working Load Limit (WLL):
The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
- Slide tandems forward 7 holes - 33,950 drive axles - 32,350 trailer tandems
- Slide tandems back 6 holes - 33,950 drive axles - 32,350 trailer tandems
- Slide tandems forward 6 holes - 33,750 drive axles - 32,550 trailer tandems
- Slide tandems back 7 holes - 33,750 drive axles - 32,550 trailer tandems
Quote From Page 0 Of The CDL Manual:
With 4 inch spacing you're moving 250 pounds per hole so you need to move 7 holes to shift a minimum of 1,700 pounds (250 x 7 = 1,750).
Quote From Page 13 Of The CDL Manual:
If the flattest side of the boulder is rounded or partially rounded, place the boulder in a crib made of hardwood fixed to deck of vehicle.
Boulder should rest on both deck and timber, with at least 3 well-separated points of contact that prevent rolling in any direction.
- They are used to supply air to the emergency brakes in the event of an air compressor failure
- They are used to supply air to the air compressor
- They are used to transport air from the tractor to the trailer on combination vehicles
- They are used to hold compressed air for the air brake system
Quote From Page 62 Of The CDL Manual:
Air storage tanks are used to hold compressed air. The number and size of air tanks vary among vehicles. The tanks will hold enough air to allow the brakes to be used several times even if the compressor stops working.
In an air brake system, emergency brakes naturally want to activate. It is the air pressure which holds the emergency brakes back and keeps them from activating. Therefor, air is not required for emergency brakes to function. Rather, if air is depleted from the air tanks, the emergency brakes will automatically engage.
- Attach tiedowns to the cargo.
- Use some kind of blocking.
- Put something heavy on top of the cargo.
- Set the cargo on friction mats.
Quote From Page 2 Of The CDL Manual:
What should you use in low-friction situations?
When there is low friction between the cargo and the deck (for example, with snow, ice, sand, gravel, and oil):
- Use tiedowns attached to the cargo.
- Use a means to improve the friction such as friction mats or tiedown that pass over the cargo.
- Use blocking and tiedowns.
- Where you can see the rear tires on the vehicle ahead of you
- Where you can see the rear license plate of the vehicle ahead of you
- As close as possible so no vehicles will cut in front of you
- At least 5 car lengths back
Quote From Page 128 Of The CDL Manual:
If stopping behind another vehicle, stop where you can see the rear tires on the vehicle ahead of you (safe gap).
Examiners do check your "safe gap" when stopped behind other vehicles. Be certain you can see the rear tires of the vehicle in front of you.
