The lifting apparatus has a support body comprising with first and second ends and an elongate opening in the support body. A movable support member has an upper portion with opening accommodating a threaded rod, and a lower portion attached to a rotatable cam that is positioned within and capable of traveling within the elongate opening of the support body. Rotation of the rod causes movement of the support member which shifts the center of gravity and causes the flange to tilt.
