ABSTRACT:
A preferred embodiment of a lifting device includes a mounting column having a first major portion extending in a first direction, and a second major portion fixedly coupled to the first major portion and extending in a second direction. The lifting device also comprises a lifting arm rotatably mounted on the second major portion of the mounting column and having a first hole formed therein for receiving a pin, a bracket fixedly coupled to the second portion of the mounting column and having a second hole formed therein for receiving the pin so that the pin restrains the lifting arm from substantial rotation about the second major portion of the mounting column, and a retaining member secured to the second major portion of the mounting column so that the bracket and the retaining member restrain the lifting arm from substantial movement in the second direction.
