发明名称 Apparatus and method for channelizer drum reformer
摘要 An apparatus and method for reforming deformed drums. Deformed drums are placed over an apparatus that expand a series of arms as a user exerts a force generally downward and outward along a sliding axis of a central mast. The apparatus is secured to a rigid mount that allows sufficient forces to be applied to the deformed drum that allow the device to reshape to a usable form. The apparatus is portable enough such that it can easily be mounted to a movable platform, for example, a construction vehicle with a typical square receiver trailer hitch.
