Abstract
A transporter for lifting and transporting a paper reel having a central core. The transporter has an upright frame at the base of which are provided a pair of ground engaging wheels. A generally cylindrical mandrel, arranged to be received by the core of a reel to be lifted, projects from the front of the frame. The mandrel comprises a deflector member which is arranged to be deflected outwardly relative to the mandrel axis as the transporter frame is tilted backwards to cause the mandrel to take the weight of a paper reel. The deflector member is thus forced against the inside of the reel core, causing the mandrel to self-lock within the core.
