    摘要： A lifting trolley having a main frame supported on ground engaging wheels, a handle pivotally connected to the main frame and a lifting sub-frame which is vertically movable with respect to the main frame is disclosed. The sub-frame has a pair of spaced apart arms, each of which include retractable engagement means in the form of pivoting catch members that are adapted to secure a load, such as a stack of crates, to the sub-frame. Linkage means, such as a pulley and cable assembly between the handle and sub-frame, enabling pivotal movement of the handle to cause vertical movement of the sub-frame with respect to the main frame is also disclosed. The trolley includes releasable catch means, such as a first catch assembly between the handle and the main frame and a second catch assembly between the sub-frame and the main frame that is adapted to lock the sub-frame to the main frame, so that only upon release of the catch means and the pivotal movement of the handle may the sub-frame be raised or lowered to a desired height.
