Low-profile vacuum tank trailer for transporting flowable material

摘要

The present invention discloses a tank trailer for transporting flowable material. The tank trailer includes a low-profile tank having a rear section, a front section, and a transitional section. The transitional section connects the rear section and the front section such that flowable material can flow among the sections. The rear section has a rear circumference and a rear center of gravity. The front section has a front circumference and a front center of gravity. The front circumference is smaller than the rear circumference, and the rear center of gravity is lower than the front center of gravity. The sections have tops that are collinearly aligned. The front section and the transitional section are frameless underneath. The tank trailer also includes a trailer suspension operatively connected to the rear section.
