The project involved the removal of old salt conveyors at a Cargill salt plant in Hersey, Michigan. The conveyors carried bags of salt overhead from the salt plant to an igloo type storage structure. The bags were then lowered down from an opening in the roof of the igloo to the floor of the igloo. Once inside the igloo the salt bags were loaded onto pallets, strapped down and stacked for eventual loading onto flatbed trailers for delivery to customers.<\/p>\n
NADC’s portion of the project involved removing the salt conveyor and salt conveyor enclosure from the slat plant to the igloo. After completing an engineered lift plan seven picks were made including the salt conveyor\/conveyor enclosure (2 picks), conveyor support legs (2 picks), steel house structure on top of the igloo (2 picks) and a small section of conveyor inside the opening to the salt plant (1 pick). Once the picks were complete the conveyors and other steel structures were cut up with a shear for recycling. The concrete piers under the conveyor’s legs were hammered down to grade with a concrete hammer on a NADC Bobcat. All the items to be picked were pre-cut by men in manlifts using torches. Once the crane was connected to each section the balance of the steel was cut to allow the crane to lower the pieces to the ground for further processing. The job was completed in six days.<\/p>\n
