Barnhart was hired to off-load, transport and set a 300-ton steam drum 300 feet in the air inside the boiler structure of a new coal fired power plant. After the vessel arrived by rail a gantry system was used to transferr it to a 14-line self-propelled Goldholfer trailer for transport to the boiler structure. The major lift of the boiler erection was completed using two of Barnhart’s 450 ton strand jacks. In order to allow for final positioning of the drum from the boiler roof, the strand jacks were mounted on hydraulic slide track. The physical constraints of the boiler structure prevented the drum from being lifted in the horizontal position. As such, the Barnhart Team raised at a pitch of up to 30° to allow for clearance during the primary lift. After it cleared the obstruction, the drum was leveled off, lifted to the targeted height and was then transferred horizontally fourteen feet into its final set position.
