Abstract: The invention contemplates portable apparatus for use in hot-bending of tubular pipe, comprising a rigid triangular frame of connected legs wherein a forming-die platform is located near one corner of the frame, along with a back-up shoe support at the corner, so that pipe-support and bending may commence from said one corner, progressing in the direction of one of the adjacent sides of the frame. The bending forces are provided by a winch mounted on the same platform and utilizing block and tackle that has anchoring reference to one or both of the remaining corners of the frame. In a preferred embodiment, the frame legs which define the platform corner are truncated into halves, whereby the platform and its adjacent leg halves comprise one of two removably securable subassemblies.
