ABSTRACT:
The lifting device comprises an upright mast section, a lifting motor, a lifting arm having one end slidably mounted in the mast section and extending outwardly therefrom, the lifting arm being pivotally connected to the motor, and a lifting fork pivotally connected to the opposite free end of the lifting arm; the lifting arm and the lifting fork, in their lowest position, extend horizontally outwardly from the mast section; the arm and the fork are hingedly mounted to and vertically-displaceable along the mast section in such a manner that, when the lifting arm is first vertically displaced from the said lowest position by the lifting motor, the lifting arm pivots about its end inside the mast section to an outward and downward inclined position while the lifting fork pivots about its end adjacent the mast section to an outward and upward inclined position; the lifting motor thereafter causes the lifting arm and the lifting fork to further travel upward along the mast section in their relative inclined position.
