Abstract
A trolley having a base section with ground engaging parts adapted to move between a collapsed condition into a deployed condition to provide a stable base for the trolley, the ground engaging parts are interconnected for synchronised movement and an upper section that connectively extends above the base section including a coupling intermediate the upper section and base section such that the upper section and base section have synchronised movement and an actuator operatively connected thereto, wherein the motion of the actuator causes the ground engaging parts to move between the collapsed and deployed condition.
