The K-34 trailer was used by the U.S. Army Signal Corps to house electronic equipment, during and after World War II.

Specifications
The fifth wheel-type trailer van was of the single-axle type, but had a dolly (trailer) so that it could be moved by other smaller vehicles. The trailer's net weight was 8,600 lb, tires were 7.50-20 8-ply, the width was 95 1/8", length was 230 7/8", and height was 121 5/8".

Usage
The K-34 trailer was originally intended to house the PE-84 generator for the SCR-268 radar but was soon used for other systems, like the AN/MPN-1 radar.
