Barnhart was hired to provide crane service to remove and replace six bulkheads at a dam in Nebraska. The team mobilized its 210-ton and 330-ton cranes to the site.
Each gate was 19.5' wide and 25' long and weighed 37,500 pounds. Barnhart’s 330-ton crane was used to remove the old gates, which were set onto cribbing and then loaded into a truck to be hauled off for scrap.
The new gates arrived by truck, were offloaded by the 210-ton crane, transferred to an on-site truck and trailer, and then picked up by the 330-ton crane to be set into their slots.
The operator set the bulkhead into slots at a 70-foot radius. The crew had to be careful not to disturb the bulkhead’s coating, which could easily be scratched or damaged. Despite these precautions, the crew finished ahead of schedule.
