    a trolley movable on said track between said first and second stations, said trolley comprising a wheel frame including wheels to facilitate movement of said trolley;

    a load support mounted on said track at said first station by an over center linkage pivotally joined at a first pivot point to said load support and at a second pivot point to said track, said first and second pivot points shifting fore and aft relative to one another in response to first and second activating means;

    said linkage being movable over center to shift said load support between first and second vertical positions relative to said track, said load support projecting above said trolley in said first vertical position and below said trolley in said second vertical positions;

    said first activating means configured for shifting said load support into said first vertical position and said second activating means configured for shifting said load support into said second vertical position;

    said first activating means operating on said load support at said first station;

    said second activating means operating on said load support at said first station whereby said trolley can be moved from said second station to said first station below a load placed on said load support at said first station with said load support in said first vertical position; and

    said second activating means activatable to lower said load support into said second vertical position and thereby transfer a load supported on said load support onto said trolley, said trolley can be moved from said first station to said second station to thereby convey said load to said second station and said first activating means can then shift said load support back into said first vertical position.
