Abstract: A detachable trailer for transporting heavy equipment and the like includes a forward tongue adapted for hitching to a towing vehicle and a support assembly for supporting the tongue on the ground at an elevation desired for hitching. The support assembly includes a screw type stand which is supported from a tongue-mounted bracket for pivotal movement between a lowered or support position wherein the stand base can be lowered into engagement with the ground and a raised or stowed position for over-the-road travel. A locking pin carried by the stand is releasably biased into engagement with angularly space apertures in the bracket to releasably retain the stand in the support and stowed positions.
