2IH uses 2 platforms that are driven upwards and downwards. Dummy platform is placed over the top of 1st platform while 2nd platform is below the 1st platform. Tiling can be done or turf can be installed on the dummy platform similar to 1IH. Pit depth required for 2IH is nearly double of that of 1IH. Cars can be parked on 1st and 2nd platforms when they are driven upwards to the ground level. When driven back to their original position, a car can be parked on dummy platform.
