A mounting assembly for holding and moving a propane cylinder between a first operational position and a second lower loading/unloading position with respect to a support structure of a forklift is provided. The mounting assembly includes a base member adapted for connection to the forklift support structure, a cradle for supporting the cylinder between the first and second positions, and first and second pivot arms having a first end pivotally connected to the base member and a second end pivotally connected to the cradle. In the first position, the cradle is in a generally horizontal orientation. In the second position, the cradle is in a generally vertical orientation. Angular movement of the first and second pivot arms causes rotation of the cradle between the generally horizontal and generally vertical orientations.
