TRAILERS

Trailers don't share their weight with another vehicle.

There are several ways to classify trailers, by weight, size, or the number of axles, I.e.: Tandem; Tridem; etc.

Another way is by the type of cargo area, I.e.: high boy; tanker; van; etc.

And of course there is no end to the combinations of those two methods, i.e.: Tandem Tanker; Tridem Van; Etc.;

Here are just a few examples:

(Gravel trailer.)

DUMP or GRAVEL
A true trailer, the front axle is permanently attached.

(Gravel (transfer) trailer.)

TRANSFER
The box from this trailer can be transfered into the box on the truck.

(Empty logging trailer.)

POLE
Equipped with a logging bunk.
The axle unit can be moved back or forth on the pole, or reach, to accommodate various lengths of cargo, poles, beams, logs, etc.

(Gravel box on a pony.)

SEMI TRAILERS

Semi trailers share their weight with a towing vehicle.

OLDER SUPER

Before the advent of; B trains, or Tridem trailers, the `Super' was; an A, or C, Train with a floating axle in the middle of the lead trailer.

(Tag axle in the center of a trailer.)

The purpose of the center axle was to support the center of the frame so the trailer could carry extra weight.
It was normally carried in the up position and lowered just before arriving at a weigh scale. Once past the scale it was usually raised again, to save wear and tear on the tires.
Consequently many trailers broke in the middle.
