A bucket elevator, also called a grain leg, is a mechanism for hauling flowable bulk materials (most often grain or fertilizer) vertically. It consists of: i) Buckets to contain the material ii)A chain drive to carry the buckets and transmit the pull, iii)Means to drive the belt iv)Accessories for loading the buckets or picking up the material, for receiving the discharged material, for maintaining the belt tension and for enclosing and protecting the elevator.[1]A bucket elevator works by connecting many buckets via chains or a conveyor belt around a powered pulley system. The buckets are first filled with bulk material at the bottom of the elevator. Then the buckets ascend the elevator ramp, until they reach the very top where the material is discharged. The buckets are designed to stay upright to prevent spillage. The head is one of the major structural elements of the overall elevator. It supports the weight of buckets and belt, and also accommodates the drive and anti-runback back device
