ABSTRACT:
A dual frame trailer for the carrying of cable reels is specifically advantageous in that it may carry large weights on a simple structure and may be manually loaded. The trailer structure comprises: (a) an axle between a set of wheels; (b) a main frame comprising: (1) a wishbone or yoke shaped structure comprising two rails parallel at their rear extremities and converging and joined at their forward extremities and normally being in an approximately horizontal plane; (2) stationary upright members depending upwardly from each of said rear extremities, each having (3) a reel bar mounting means attached at each upper end of the stationary upright support member, each support member further characterized as having an aperture for the accommodation of a pin at a point lower than reel bar support, and (4) braces each extending from the upper part of the reel bar support to said rail to form a triangle with said support and the main frame being pivotally attached at each rear extremity to opposite ends of the axle, and (c) a rocker frame comprising a pair of identically shaped frames lying in parallel vertical planes opposing one another and connected by means of bracing rails and each identically shaped frame pivotally attached at one angle to said axle in opposing relationship to one another at each end of said axle and each pair of identically shaped frames having reel bar support means at opposing ends of each identical frame, the upper most rail of each of the identical frames having an aperture for the accommodation of a pin for connecting to the main frame when the aperture is in alignment with a corresponding aperture in each of the support members of the main frame.
