Overhead Monorail cranes provide movements along two axes. Up and down movement via the hoist and forward and backward movement via the monorail beam.A trolley (pictured below) is a wheeled mechanism from which a hoist is suspended to provide horizontal motion of the hoist along a beam/bridge rail.
