A unitized hydraulic suspension system for a tandem front and back two-axle group comprises two pivoting arms, each for supporting one of the two axles, arranged on opposite sides of a common rigid hanger. Each arm is attached to one end of a respective cylinder the other end of which cylinder is attached to the common hanger. The unitized hydraulic suspension simplifies the use of hydraulic suspension in dual laning heavy haul applications by the provision of a slide assembly in which unitized hydraulic suspensions are slidably mounted so as to be extendible or retractable in relation to one another.

Unitized hydraulic suspension system

A removable gooseneck hitch assembly transitions between an afterward position for hitching to a low bed trailer deck and a forward position by a pivoting arm that moves the forward end of the gooseneck an arcuate path. The invention minimizes the opportunity for debris to interfere with the sliding track assemblies known in the prior art. The assembly provides three degrees of freedom for the gooseneck in low bed mode and restricts the degrees of freedom in vehicle towing mode. A locking member for securing a low bed trailer hitch is also disclosed.
