Abstract

The invention provides a light-weight mechanism that restricts rotation of a multi- wheel assembly by a ratchet and, when desired, lifts one of the ground-contacting wheels for manoeuvrability. An arm mountable on the handcart pivots from a disengaged position into an engaged position where the arm engages with the multi- wheel. A ratchet finger on the arm then restricts rotation of the multi- wheel (e.g. so that the multi- wheel can rotate backwards but not forwards, or vice versa). Further movement of the arm also lifts one of the ground-contacting wheels.
