<p>The trolley comprises a base (10) on which are mounted radius arms (20, 21) providing support to a trolley surface. The radius arms (20, 21) are connected to actuators (11, 12) operated by pedals (13b, 14b, 13a, 14a) respectively (or both simultaneously by pedal (15b or 15a) not shown) to raise or lower the trolley surface. The sets of pedals may be fitted on either side or both side of the trolley. The trolley comprises safety side rails (50, 51) which are stowable under their own weight to lie under the trolley surface.</p> |
