New Poe Lock Arrestor Arm is Largest U.S. Civil Works Component Produced by 3D Printer
In February 2023, cracks were found in one of the 60-year-old lever arms used to raise and lower a large boom on the Poe Lock’s arresting system. Temporary repairs were made so the lock could operate during the 2023 navigation season.
USACE considered several design options and ultimately selected 3D printing as the best option, awarding the contract for the lever arms to Lincoln Electric.
The Soo Locks mechanical ship arresting system protects the lock’s miter gates, a critical system component, from an emergency impact with a ship. Each lock has two arrestors – one located upstream of each miter gate.
