Each arm is mounted on a fulcrum and carries a wheel on the end extending from the housing so that on each side of the dishrack there are a pair of wheels engaging a supporting guide track that forms a part of the dishwasher with the tracks being projected outwardly when projecting the dishrack outwardly for loading and unloading. Each housing encloses worm wheel sector gears on the arms and a corresponding single worm gear engaging the sector gears for adjusting the arms about their fulcrums and thereby adjusting the vertical position of the dishrack.
