The 44EXP is an ultra-lightweight trailer designed to maximize potential payloads in conformance with California statutory lengths and axle group loadings.
To provide for the maximum allowable axle weights, the 44EXP make use of an Expando Trunnion suspension system, which employs eight tires per axle line in a tandem trunnion configuration. This gives the operator the ability to telescope from a standard 8-foot 6-inch overall width to a 10-foot maximum tire width. This capability coupled with the axle spacing provides for maximum available loadings in states recognizing trunnion axles, according to Fontaine.
Fontaine said it is the only company that combines the advantages of the trunnion expando configuration with an air-ride system. Fontaine’s patented air ride trunnion protects the trailer frame and cargo from shock loads imparted from normal dynamic loadings, said the company.
