Air Hoists Help Speed Propeller Repair At Todd's Seattle Yard

When a large oil tanker with a broken propeller entered Todd Shipyards in Seattle, Wash., for repairs recently, yard officials moved fast with an innovative plan to get the vessel operable again.

To speed up repairs, the tanker was kept afloat and ballast placed in the bow to raise the stern. Rafts were secured in the stern area from which the repair crew worked.

A critical phase of the project was the use of two 50-ton-capacity air hoists furnished by Neuhaus America Corporation to lift and hold the propeller in suspension.

The air hoists, which have a combined weight of 4,000 pounds, were shipped air freight by Neuhaus from its plant in Sparks, Md., near Baltimore. The hoists were in service 24 hours after Todd placed the order.

Each of the Neuhaus hoists is capable of lifting a 50-ton ship's propeller to a height of more than 3 feet in 90 seconds. With easy access to the damaged propeller and the flexibility to readily move or turn it, which the hoists provided, the repair crew completed the job in record time.
