A trolley having a base 1 supported on wheels 2 with upright members 5, 6 upstanding from the base, includes a retractable sack holder 10. The sack holder has a support frame 13, 14, a lower portion of which is pivotally mounted for angular movement between retracted (figure 3) and extended positions of the sack holder, and a top frame 12 for holding an open mouth of a sack suspended below the top frame. The top frame is pivotally connected to a top portion of the support frame and the trolley includes a pair of runners 7 supported from the upright members. The runners extend generally parallel to the base, and a rear edge of the top frame may be provided with pairs of rollers (35, 36 figure 2) which are engaged with the runners to travel along them as the sack holder moves between the retracted and extended positions. The arrangement minimises the angular movement of the top frame which allows the space within the trolley to be utilised more fully. |
