Properly attach air lines, electrical line and other associated hoses (if applicable). Charge air system and if equipped with a “no-slack ram”, do a tug test to ensure the ram is energized. Perform a visual inspection to ensure all locking mechanisms are properly secured. Place landing leg (if applicable) in transport position and remove chocks. Ensure hitching devices are secure and re-check safety latch. The most important task in the coupling procedure is to physically and visually check all connections. Failure to do so may be the cause of a serious incident. Coupling mechanisms Double trailer combination types A train – example of a unit connected by a type A converter dolly. B train In a B train, the converter is part of the lead trailer. The fifth wheel assembly sits on the rear axle of the lead trailer. It is either permanently fixed in position or slides out with the rear axle. No converter dolly is required, as the second unit connects directly to the extended frame of the lead unit. When adding a second trailer to the rear of a lead trailer, a converter mechanism is needed. Each converter must have its own fifth wheel attachment. There are three different types of converters. A train This converter has an A shaped drawbar that joins into a single pintle hitch point on the lead trailer. Due to its A shape, it is often called an A-dolly. When two trailers are joined together using the A-dolly, the whole unit is called an A train. These converters provide two points of articulation (joints that allow side to side or lateral movement). One of these points is at the pintle and the other is at the fifth wheel. B train – example of a unit connected by a type B converter dolly. C train A C train is like the A train, in that it uses an independent converter. The difference between the two is that the C train has two drawbars and two pintle hitches in the double drawbar converter. CHAPTER FOUR Operating Class 1 Vehicles 45
Two bars mean there is only one articulation point. The result is that the trailer moves less from side-to-side. To improve performance even more, double drawbar converters have a self-steering axle. When driving a C train, check that the air pressure on the self-steering axle is within the manufacturer’s standards. If the air pressure falls too low, the wheels will steer too much and the unit becomes unstable. This can lead to skid steering, which can damage the converter and hitch. Examples of long combination vehicles Rocky Mountain Double Triple Turnpike Double C train – example of a unit connected by a type C converter dolly. Link-up arrangement When linking two or more trailers to a towing unit, always hook the heaviest trailer directly to the tractor. The lightest trailer should be the furthest away from the towing unit. This rule applies no matter how long each trailer is. If the trailers are not joined according to weight, the unit will be unstable. The rear trailer will sway and control of the unit could be lost. Operating long combination vehicles When a permit is issued according to Section 62 of the Traffic Safety Act authorizing the movement of Long Combination Vehicles (LCVs), a list of general provisions must be followed. Some of these provisions are listed below. Note: For a complete, current list of all provisions, carriers who wish to operate LCVs should contact the Transport Engineering Branch at (403) 340-5189. For toll-free service from anywhere in Alberta, call 310-0000. 46 A Commercial Driver’s Guide to Operation, Safety and Licensing
