Dorman Long supplied a 4 x DL-S418 strand jack system to industrial crane services based in Mississippi US for erection and modification of container cranes. To handle the increased workload along the eastern coast of USA due to the upgrade of the Panama Canal, these container cranes were built to handle larger container ships. There was a mix of lifting and lowering operations involved before these container cranes were loaded out on a barge and moved to Puerto Rico where they were re-erected using DLT strand jacks.
