ABSTRACT:
A hand trolley for lifting and moving an object comprises a support frame for the object and a wheel assembly coupled to the support frame by means of a link arm 33 on each side of the trolley. Each link arm is connected at one end to the axle 31 of the wheel assembly and pivotally connected at the other end to the support frame. In a carry position of the trolley, at which the object is supported on the wheel assembly, the link arms 33 are located in a locked position so as to lock together the wheel assembly and the support frame when an operator pulls the trolley rearwardly over an obstacle.
