Answer» The correct answer is (d) Overhead hopper For explanation I would say: Basically, an overhead hopper is used in jolt mould method of ramming, in which after filling the sufficient amount of sand to the mould, an overhead hopper is raised to a certain height and then it is allowed to free fall on to a solid bed plate, which results into the ramming and packing of sand layers in the mould. |
