A) B-train lead trailer with aluminum frame
B) A-train lead trailer with pintle hook
C) yard shunt

Compensating Fifth Wheel

A fifth wheel designed to articulate fore and aft, and side to side. Used to limit trailer torque effect transfer; the Holland Kompensator would be an example.

Aluminum Frame

An aluminum frame refers to the structural framework of a vehicle or equipment made from aluminum, known for being lightweight yet strong.

Pintle Hook

The standard coupling mechanism used in truck full-trailers. The function of a pintle hook is to engage to the drawbar eye, which itself is bolted to the tongue or drawbar assembly of the trailer.
