E - Trailer Systems and Components Flashcards
The main advantage of using a deck trailer to carry cargo is:
Easy access for loading and unloading.
A highboy trailer has the deck located:
Above the tractor/trailer wheels and suspension components.
Two advantages of a lowboy deck trailer are:
Higher loads can be carried and the centre of gravity of the load is lower, increasing stability.
Trailers that protect the load from environmental conditions are called:
Van trailers.
Temperature-controlled trailers:
Keep the cargo at a constant temperature.
True or False: Tank type trailers are designed to carry liquid cargo only.
False; Tank type trailers can also carry granular/ dry type materials.
Trailers that can be lengthened or shortened to accommodate loads of varying length are called:
Extendable.
Vehicle ground pressure is a measure of?
The amount of force created by the combined weight of the vehicle and its load divided by the area of contact between the vehicle’s tires and the road surface.
What type of coupling device is used to connect a pony trailer to a body loaded truck?
A pintle hook.
How many points of articulation are there on a body loaded truck and pony trailer?
1
A tractor and single semi-trailer are connected using a (?) coupling and has (?) point of articulation.
Fifth wheel; one
The unit that takes some of the weight off of the tractor when oversized loads are being hauled is called a:
Jeep.
The unit that takes some of the weight off of the tractor when oversized loads are being hauled is called a:
Converter dolly.
B train combinations are more stable during operation than A trains because:
The following semi-trailer is connected to the lead trailer by a fifth wheel and kingpin connection that provides only one point of articulation.
The device that connects the following trailer to the lead trailer by two or more pintle hooks, couplers, and drawbars is called a:
C train dolly.
