Abstract
A frame for a heavy-duty vehicle trailer includes a pair of elongated, spaced-apart parallel main members, each one having a pair of spaced apart parallel vertical walls. At least one cross member extends between and attaches to the main members, and includes a pair of spaced apart parallel transversely-extending vertical walls. Each one of a first pair of hangers includes a pair of spaced-apart parallel vertical walls that generally align and attach to the main member vertical walls. Each hanger includes a hanger support having a pair of spaced apart parallel vertical webs integrally formed with a diagonally extending side member. The hanger support attaches to the inboard hanger wall and also to the cross member. The frame reduces weight and provides improved reaction of longitudinal and side loads, yet still efficiently reacts vertical and racking loads imparted on the frame during operation of the vehicle.
