A lifting apparatus for lifting a load such as a motorcycle. The apparatus includes a base and a load support which may be placed under the load to be lifted. The base and load support each include vertical columns, one column being positioned in the other column so that the columns telescope to raise and lower the load support. A lever operable cam is secured to the base at a pivot having a horizontal axis and the cam surface is in contact with a cam follower secured to the load support. The lever pivots the cam so as to raise and lower the load support. The cam surface configuration keeps the load support in either the raised or lower position until the lever is operated.
